DatePickerButtonElement DatePickerButtonElement is a compound button that creates a pop-up DatePicker where the user can select a date which is then displayed on the button. The DatePickerButtonElement button itself contains a child button which is used to render the divider line and arrow. DatePickerButtonElement proxies its SkinState style to the arrow button so the arrow button will change states along with the DatePickerButtonElement itself. See the default skin for the arrow button DropdownArrowButtonSkinElement for additional styles. Inheritance:     DatePickerButtonElement ➞ DropdownBaseElement ➞ ButtonElement ➞ SkinnableElement ➞ CanvasElement ➞ StyleableBase ➞ StyleDefinition ➞ EventDispatcher ➞ Object Styles Show Inherited Style Defined By AllowDeselect     :    boolean DatePickerButtonElement When false, the DatePicker day ToggleButtons cannot be de-selected by the user and the "selectedOver" and "selectedDown" states are not used.   DateFormatLabelFunction     :    Function DatePickerButtonElement A function that accepts a date and returns a string to be displayed as the date label. Signature: function (date) { return "" } The default label function returns returns international date format "YYYY-MM-DD".   PopupDatePickerDistance     :    Number DatePickerButtonElement Vertical distance in pixels to place the DatePicker pop up from the button. Defaults to -1 to collapse default 1 pixel borders.   PopupDatePickerStyle     :    StyleDefinition DatePickerButtonElement The StyleDefinition or [StyleDefinition] array to apply to the pop up DatePicker element.   Style Defined By AllowDeselect     :    boolean DatePickerButtonElement When false, the DatePicker day ToggleButtons cannot be de-selected by the user and the "selectedOver" and "selectedDown" states are not used.   Alpha     :    Number CanvasElement Alpha value to use when rendering this component. Allowable values are between 0 and 1 with 0 being transparent and 1 being opaque. This causes the element to perform composite rendering when a value between 1 and 0 is used.   ArrowButtonClass     :    CanvasElement DropdownBaseElement The CanvasElement or subclass constructor to be used for the arrow icon. Defaults to Button. Note that Dropdown proxies its SkinState style to the arrow button so the arrow will change states with the Dropdown.   ArrowButtonStyle     :    StyleDefinition DropdownBaseElement The StyleDefinition or [StyleDefinition] array to apply to the arrow icon class.   BackgroundFill     :    FillBase CanvasElement Fill to use when filling the background. May be any FillBase subclass instance, "color" string, or null for transparent.   BackgroundShape     :    ShapeBase CanvasElement Shape to be used when rendering the elements background. May be any ShapeBase subclass instance.   BorderColor     :    String CanvasElement Hex color value to be used when drawing the border. Format like "#FF0000" (red)   BorderThickness     :    Number CanvasElement Thickness in pixels to be used when drawing the border.   BorderType     :    String CanvasElement Determines the border type the CanvasElement should render. Allowable values are "solid", "inset", "outset" or "none" / null. Note that borders are internal and drawn on the inside of the elements bounding area.   Bottom     :    Number CanvasElement The distance the element should be positioned from the lower bounds of the parent container. This only works if the element is a child of an AnchorContainer.   ClipContent     :    boolean CanvasElement Determines if out of bounds rendering is allowed. If true the element will clip all rendering and children's rendering to the elements bounding box. This style is inheritable for container elements.   CompositeLayer     :    boolean CanvasElement When true, this element renders itself and all children to a single layer and is treated by its parent as a single element when rendering. This is necessary and automatically enabled for styles like alpha where the component and all its children must be pre-rendered, and then re-rendered with the appropriate effect. This is very expensive but can also be very beneficial when used appropriately. For example, if you have an application with a scrolling or constantly changing background thereby always causing a full screen redraw, its beneficial to make the layer on top of the background a composite layer. This effectively buffers the layer. Only the delta changes will be drawn to the composite. Otherwise the entire display chain would have to be re-drawn when the background moves. This is memory intensive as it effectively duplicates the rendering area. Composite elements/children changing will update their region of their composite parent, then that region of the composite parent needs to be copied up to the grandparent, resulting in an additional buffer copy.   Cursor     :    CursorDefinition CanvasElement Specifies the cursor to be displayed when the mouse is over the element. A custom CursorDefinition may be used or a browser type String ("text", "none", etc) may be used.   DateFormatLabelFunction     :    Function DatePickerButtonElement A function that accepts a date and returns a string to be displayed as the date label. Signature: function (date) { return "" } The default label function returns returns international date format "YYYY-MM-DD".   DisabledSkinClass     :    CanvasElement ButtonElement The CanvasElement constructor to be used for the button skin when the button is in the "disabled" state. This will override SkinClass when equal or higher priority than SkinClass.   DisabledSkinStyle     :    StyleDefinition ButtonElement The StyleDefinition or [StyleDefinition] array to apply to the "disabled" state skin element.   DisabledTextColor     :    String ButtonElement Hex color value to be used for the button label when the button is in the "disabled" state. Format like "#FF0000" (red). This will override TextColor when equal or higher priority than TextColor.   DownSkinClass     :    CanvasElement ButtonElement The CanvasElement constructor to be used for the button skin when the button is in the "down" state. This will override SkinClass when equal or higher priority than SkinClass.   DownSkinStyle     :    StyleDefinition ButtonElement The StyleDefinition or [StyleDefinition] array to apply to the "down" state skin element.   DownTextColor     :    String ButtonElement Hex color value to be used for the button label when the button is in the "down" state. Format like "#FF0000" (red). This will override TextColor when equal or higher priority than TextColor.   Draggable     :    boolean CanvasElement When true allows the element to be dragged by the user. This does not work for containers that do not allow absolute positioning such as a ListContainer.   Enabled     :    boolean CanvasElement When false disables user interaction with the element.   FocusColor     :    String [Inheritable] CanvasElement Hex color value to be used when drawing the elements focus indicator. Format "#FF0000" (Red). The focus indicator is only rendered when the element gains focus due to a tab stop.   FocusThickness     :    Number [Inheritable] CanvasElement Size in pixels that the focus ring should be rendered. Note that the focus ring is rendered outside the elements bounding area.   Height     :    Number CanvasElement The Height the element should be rendered relative to its parent container. This only works if the element is a child of a Container element.   HorizontalCenter     :    Number CanvasElement The distance in pixels from the horizontal center of the parent the element should be positioned. Negative numbers indicate left of center, positive right of center. This only works if the element is a child of an AnchorContainer.   IncludeInLayout     :    boolean CanvasElement When false, the element is no longer considered in the parent container's layout. Typically this is used in conjunction with Visible, however sometimes you may want to hide an element, but still have it consume container space.   IncludeInMeasure     :    boolean CanvasElement When false, the element is no longer considered in the parent container's measurement. This is useful if you do not want containers to respect this child's measured size and/or do not care if content is clipped, such as when using MinSize, MaxSize, and percent sizing together. This also prevents the element's _doMeasure() function from running and forces a 0x0 measured size. However, this will not prevent the "measurecomplete" event after this element finishes its measure phase.   Left     :    Number CanvasElement The distance the element should be positioned from the left most bounds of the parent container. This only works if the element is a child of an AnchorContainer.   MaxHeight     :    Number CanvasElement The maximum height in pixels the element should consume. This only works if the element is a child of a Container element.   MaxWidth     :    Number CanvasElement The maximum width in pixels the element should consume. This only works if the element is a child of a Container element.   MinHeight     :    Number CanvasElement The minimum height in pixels the element should consume. This only works if the element is a child of a Container element.   MinWidth     :    Number CanvasElement The minimum width in pixels the element should consume. This only works if the element is a child of a Container element.   MouseEnabled     :    boolean CanvasElement When false disables mouse events for the element.   OpenCloseTweenDuration     :    Number DropdownBaseElement Duration in milliseconds the open and close animation should run.   OpenCloseTweenEasingFunction     :    Function DropdownBaseElement Easing function used on the open and close animations. Defaults to Tween.easeInOutSine().   OverSkinClass     :    CanvasElement ButtonElement The CanvasElement constructor to be used for the button skin when the button is in the "over" state. This will override SkinClass when equal or higher priority than SkinClass.   OverSkinStyle     :    StyleDefinition ButtonElement The StyleDefinition or [StyleDefinition] array to apply to the "over" state skin element.   OverTextColor     :    String ButtonElement Hex color value to be used for the button label when the button is in the "over" state. Format like "#FF0000" (red). This will override TextColor when equal or higher priority than TextColor.   Padding     :    Number CanvasElement Size in pixels that inner content should be spaced from the outer bounds of the element. Padding effects all sides of the element. Padding may be negative under certain circumstances like expanding an inner child to allow border collapsing with its parent.   PaddingBottom     :    Number CanvasElement Size in pixels that inner content should be spaced from the lower bounds of the element. This will override the Padding style.   PaddingLeft     :    Number CanvasElement Size in pixels that inner content should be spaced from the left most bounds of the element. This will override the Padding style.   PaddingRight     :    Number CanvasElement Size in pixels that inner content should be spaced from the right most bounds of the element. This will override the Padding style.   PaddingTop     :    Number CanvasElement Size in pixels that inner content should be spaced from the upper bounds of the element. This will override the Padding style.   PasswordMaskCharacter     :    String [Inheritable] CanvasElement Character to use when masking a password field   PercentHeight     :    Number CanvasElement The percentage of available height the element should consume relative to its parent container. This only works if the element is a child of a Container element. Note that percentage height is calculated based on the available space left over *after* static sized elements considered. Percentages are allowed to add to more than 100 and will consume all of the available space. For containers like ListContainers, when percents add to more than 100 the elements will share the available space per the ratio of percent vs total percent used so it is perfectly reasonable to set 3 elements all to 100 and allow them to split the real-estate by 3.   PercentWidth     :    Number CanvasElement The percentage of available width the element should consume relative to its parent container. This only works if the element is a child of a Container element. Note that percentage width is calculated based on the available space left over *after* static sized elements considered. Percentages are allowed to add to more than 100 and will consume all of the available space. For containers like ListContainers, when percents add to more than 100 the elements will share the available space per the ratio of percent vs total percent used so it is perfectly reasonable to set 3 elements all to 100 and allow them to split the real-estate by 3.   PopupDatePickerDistance     :    Number DatePickerButtonElement Vertical distance in pixels to place the DatePicker pop up from the button. Defaults to -1 to collapse default 1 pixel borders.   PopupDatePickerStyle     :    StyleDefinition DatePickerButtonElement The StyleDefinition or [StyleDefinition] array to apply to the pop up DatePicker element.   Right     :    Number CanvasElement The distance the element should be positioned from the right most bounds of the parent container. This only works if the element is a child of an AnchorContainer.   RotateCenterX     :    Number CanvasElement The X position of the parent container the element should be rotated around. This only works if the element is a child of an AnchorContainer.   RotateCenterY     :    Number CanvasElement The Y position of the parent container the element should be rotated around. This only works if the element is a child of an AnchorContainer.   RotateDegrees     :    Number CanvasElement The number of degrees the element should be rotated (clockwise). When no RotateCenterX or RotateCenterY is set, the element is rotated via its center point and rotated objects are still positioned relative to their parent's coordinate plane after the transform has occurred.   ShadowColor     :    String CanvasElement Hex color value to be used when drawing the drop shadow. This may be set to null and no shadow will be rendered. Format like "#FF0000" (red)   ShadowOffsetX     :    Number CanvasElement X offset that the drop shadow will be rendered.   ShadowOffsetY     :    Number CanvasElement Y offset that the drop shadow will be rendered.   ShadowSize     :    Number CanvasElement Size in pixels that the drop shadow should be rendered. Note that the drop shadow may be rendered outside the elements bounding area. This will cause the element to be composite rendered.   SkinClass     :    CanvasElement ButtonElement The CanvasElement constructor type to apply to all skin states. Specific states such as UpSkinClass will override SkinClass when they are equal priority.   SkinState     :    String CanvasElement This is an internal style used to toggle an element's current skin for different states such as normal, mouse-over, mouse-down, etc. Its also commonly used by skin classes to identify their skin state.   TabStop     :    int CanvasElement Determines if an element can be focused using tab stops. -1 indicates the element cannot take focus, 0 is default and the element will be focused in the order it appears in the display chain. Numbers higher than 0 indicate a specific order to be used (not yet implemented).   Text     :    String ButtonElement Text string to be displayed as the button label.   TextCaretColor     :    String [Inheritable] CanvasElement Hex color value to be used when drawing blinking text caret. "#FF0000" (red)   TextColor     :    String [Inheritable] CanvasElement Hex color value to be used when drawing text. Format like "#FF0000" (red)   TextDecoration     :    String [Inheritable] CanvasElement Determines the text decoration used. Available values are "none" or "underline".   TextFillType     :    String [Inheritable] CanvasElement Determines the fill type when rendering text. Available values are "fill" and "stroke". Stroke draws a border around characters, while fill completely fills them.   TextFont     :    String [Inheritable] CanvasElement Determines the font family to use when rendering text such as "Arial".   TextHighlightedColor     :    String [Inheritable] CanvasElement Hex color value to be used when drawing highlighted text. Format like "#FF0000" (red)   TextHorizontalAlign     :    String ButtonElement Determines alignment when rendering text. Available values are "left", "center", and "right".   TextLinePaddingBottom     :    Number [Inheritable] CanvasElement Padding to apply to the bottom of each line of text. This also impacts the size of the highlight background. This is useful when using strange fonts that exceed their typical vertical bounds.   TextLinePaddingTop     :    Number [Inheritable] CanvasElement Padding to apply to the top of each line of text. This also impacts the size of the highlight background. This is useful when using strange fonts that exceed their typical vertical bounds.   TextLineSpacing     :    Number [Inheritable] CanvasElement Vertical line spacing in pixels.   TextSize     :    int [Inheritable] CanvasElement Determines the size in pixels to render text.   TextStyle     :    String [Inheritable] CanvasElement Determines the style to render text. Available values are "normal", "bold", "italic", and "bold italic".   TextVerticalAlign     :    String ButtonElement Determines the baseline when rendering text. Available values are "top", "middle", or "bottom".   Top     :    Number CanvasElement The distance the element should be positioned from the upper bounds of the parent container. This only works if the element is a child of an AnchorContainer.   UpSkinClass     :    CanvasElement ButtonElement The CanvasElement constructor to be used for the button skin when the button is in the "up" state. This will override SkinClass when equal or higher priority than SkinClass.   UpSkinStyle     :    StyleDefinition ButtonElement The StyleDefinition or [StyleDefinition] array to apply to the "up" state skin element.   UpTextColor     :    String ButtonElement Hex color value to be used for the button label when the button is in the "up" state. Format like "#FF0000" (red). This will override TextColor when equal or higher priority than TextColor.   VerticalCenter     :    Number CanvasElement The distance in pixels from the vertical center of the parent the element should be positioned. Negative numbers indicate left of center, positive right of center. This only works if the element is a child of an AnchorContainer.   Visible     :    boolean CanvasElement When false the element will not be rendered.   Width     :    Number CanvasElement The Width the element should be rendered relative to its parent container. This only works if the element is a child of a Container element.   X     :    Number CanvasElement The X position the element should be rendered relative to its parent container.

Dispatched when an element has completed its layout phase. This is used when it is necessary to wait for an element to finish its layout pass so things such as its PercentWidth calculation is complete. This is very expensive and should only be used when absolutely necessary. Its usually only needed when elements are not directly related via parent/child. For example, DropdownElement uses this to adjust the height of the dropdown popup since we do not know how much height it will need until after it has finished layout.   localechanged     :    DispatcherEvent [Broadcast] CanvasElement Dispatched when CanvasManager's locale selection changes.   measurecomplete     :    DispatcherEvent CanvasElement Typically an internal event. Dispatched when an element has completed its measure phase. This is used when it is necessary to wait for an element to finish its measure pass so that its content size or _measuredSize calculation is complete. This is very expensive and should only be used when absolutely necessary. Its usually only needed when elements are not directly related via parent/child. For example, ViewportElement uses this to invoke a layout pass when its content child changes _measuredSize. The Viewport uses an intermediate CanvasElement as a clipping container for the content child, which does not measure children, so an event is needed to notify the Viewport.   mousedown     :    ElementMouseEvent CanvasElement Dispatched when the mouse is pressed over this element.   mousemove     :    ElementMouseEvent CanvasElement Dispatched when the mouse moves over this element.   mousemoveex     :    ElementMouseEvent [Broadcast] CanvasElement Dispatched when the mouse moves anywhere, even outside of the browser window. Mouse coordinates are relative to CanvasManager.   mouseup     :    ElementMouseEvent CanvasElement Dispatched when the mouse is released. Note that the mouse may not still be over the element.   opened     :    DispatcherEvent DropdownBaseElement Dispatched when the pop up is opened as a result of user input.   removed     :    AddedRemovedEvent CanvasElement Dispatched when this element is removed from the display hierarchy and is no longer a descendant of CanvasManager.   resize     :    DispatcherEvent CanvasElement Dispatched when the element's size changes.   rollout     :    ElementEvent CanvasElement Dispatched when the mouse moves outside of this element.   rollover     :    ElementEvent CanvasElement Dispatched when the mouse moves over this element.   stylechanged     :    StyleChangedEvent StyleDefinition Dispatched when a style is added, cleared, or changed.   wheel     :    ElementMouseWheelEvent CanvasElement Dispatched when the mouse wheel is rolled while over this element.   Public Functions Show Inherited Function Defined By DatePickerButtonElement() [Constructor] DatePickerButtonElement Creates new DatePickerButtonElement instance.   getSelectedDate() DatePickerButtonElement Gets the selected date of the DatePickerButton.   returns     :    Date Currently selected date or null if none selected.   setSelectedDate(date) DatePickerButtonElement Sets the selected date of the DatePickerButton.   date     :    Date Date to set as the selected date or null for no selection.   Function Defined By DatePickerButtonElement() [Constructor] DatePickerButtonElement Creates new DatePickerButtonElement instance.   addCaptureListener(type, callback) CanvasElement Registers an event listener function to be called during capture phase.   type     :    String String representing the event type.   callback     :    Function Function to be called when the event occurs.   addEventListener(type, callback) EventDispatcher Registers an event lister function to be called when an event occurs.   type     :    String String representing the event type.   callback     :    Function Function to be called when the event occurs.   addStyleDefinition(styleDefinition) CanvasElement Adds a style definition to the end element's definition list. Styles in this definition will override styles in previously added definitions (lower index). Instance styles, set using setStyle() will override all definition styles. Adding style definitions to elements already attached to the display chain is expensive, for better performance add definitions before attaching the element via addElement()   styleDefinition     :    StyleDefinition The StyleDefinition to add and associate with the element.   returns     :    StyleDefinition The style definition just added.   addStyleDefinitionAt(styleDefinition, index) CanvasElement Inserts a style definition to this elements definition list at the specified index. Definitions with higher indexes (added later) are higher priority. Instance styles, set using setStyle() will override all definition styles. Adding style definitions to elements already attached to the display chain is expensive, for better performance add definitions before attaching the element via addElement()   styleDefinition     :    StyleDefinition StyleDefinition to be added to this elements definition list.   index     :    int The index to insert the style definition within the elements definition list.   returns     :    StyleDefinition Returns StyleDefinition just added when successfull, null if the StyleDefinition could not be added due to the index being out of range or other error.   clearStyle(styleName) StyleDefinition Clears style data from this object. This is the same passing undefined to setStyle().   styleName     :    String String representing the style to clear.   clearStyleDefinitions() CanvasElement Removes all style definitions from the element. This is more efficient than removing definitions one at a time.   close(animate) DropdownBaseElement Closes the pop up.   animate     :    boolean When true animates the disappearance of the pop-up.   dispatchEvent(event) EventDispatcher Dispatches an event to be processed by registered event listeners. The Event's target is the EventDispatcher which called dispatchEvent. The Event will be cloned prior to passing to callback functions to ensure the callback cannot modify the Event data or properties. You can check if the event was canceled by calling the Event's getIsCanceled after dispatching it. Re-dispatching the same event will re-set its canceled state to false.   event     :    DispatcherEvent The DispatcherEvent class or subclass to be dispatched.   getManager() CanvasElement Gets the CanvasManager currently associated with this element.   returns     :    CanvasManager The CanvasManager currently associated with this element.   getMetrics(relativeToElement) CanvasElement Gets a DrawMetrics object containing the elements bounding box information x, y, width, height, relative to the supplied element regardless of this element's transformation, depth, or position in the display hierarchy. For example, you can call this get the elements width and height, or to get this element's bounding box relative to the canvas or any other element.   relativeToElement     :    CanvasElement The element to translate this elements bounding box too. If relativeToElement equals null or this, will return metrics relative to this element: {x:0, y:0, width:thisWidth, height:thisHeight}.   returns     :    DrawMetrics DrawMetrics of this element relative to the supplied element.   getMouseIsDown() CanvasElement Gets the state of the mouse for this element.   returns     :    boolean Returns true if the mouse is currently pressed, false otherwise.   getName() CanvasElement Gets the name associated with this element.   returns     :    String The name associated with this element.   getNumStyleDefinitions() CanvasElement Gets the number of style definitions associated with this element.   returns     :    int The number of style definitions.   getParent() CanvasElement Gets this element's parent element.   returns     :    CanvasElement This element's parent element.   getSelectedDate() DatePickerButtonElement Gets the selected date of the DatePickerButton.   returns     :    Date Currently selected date or null if none selected.   getStyle(styleName) [Override] CanvasElement Gets the style value for this element. When retrieving a style, CanvasElements look through their associated style chain, at each step if undefined is returned, they look at the next step until a non-undefined value is found. 1) Instance - Styles set directly to the element via setStyle() 2) StyleDefinitions - Styles associated via its assigned StyleDefinitions 3) StyleProxy - If proxy element is assigned, move to proxy element and repeat steps 1-3 4) Inheritable - If style is inheritable, move up to parent element and repeat steps 1-4 5) Default styles   styleName     :    String String representing the style value to be returned.   returns     :    Any Returns the associated style value if found, otherwise undefined.   getStyleData(styleName) StyleableBase Gets the style data for the supplied style name, this includes additional info than getStyle() such as the style priority. You should not modify the returned StyleData.   styleName     :    String String representing style to return the associated StyleData.   returns     :    StyleData Returns the associated StyleData   getStyleDefinitionAt(index) CanvasElement Gets the style definition at the supplied zero base index.   index     :    int Index of the style definition to return;   returns     :    StyleDefinition The style defenition at the supplied index, or null if index is out of range.   getStyleDefinitionIndex(styleDefinition) CanvasElement Returns the index of the supplied style definition or -1 if the style definition has not been added.   styleDefinition     :    StyleDefinition StyleDefinition to return associated index.   returns     :    int Index of the StyleDefinition supplied via the styleDefinition parameter, or -1 if does not exist.   hasCaptureListener(type, callback) CanvasElement Checks if an event capture listener has been registered with this CanvasElement   type     :    String String representing the event type.   callback     :    Function Function callback to be called when the event occurs. This may be null to check if the CanvasElement has any capture events registered for the provided type.   returns     :    boolean Returns true if the CanvasElement has the provided capture callback registered for the provided type, or any capture callback for the provided type if the callback parameter is null. Otherwise, returns false.   hasEventListener(type, callback) EventDispatcher Checks if an event listener has been registered with this EventDispatcher   type     :    String String representing the event type.   callback     :    Function Function callback to be called when the event occurs. This may be null to check if the EventDispatcher has any events registered for the provided type.   returns     :    boolean Returns true if the EventDispatcher has the provided callback registered for the provided type, or any callback for the provided type if the callback parameter is null. Otherwise, returns false.   open(animate) DropdownBaseElement Opens the pop up.   animate     :    boolean When true animates the appearance of the pop-up.   removeCaptureListener(type, callback) CanvasElement Removes a capture event listener.   type     :    String String representing the event type.   callback     :    Function Function callback to be removed.   returns     :    boolean Returns true if the callback was successfully removed, otherwise false such as if the function callback was not previously registered.   removeEventListener(type, callback) EventDispatcher Removes a callback from the EventDispatcher   type     :    String String representing the event type.   callback     :    Function Function callback to be removed.   returns     :    boolean Returns true if the callback was successfully removed, otherwise false such as if the function callback was not previously registered.   removeStyleDefinition(styleDefinition) CanvasElement Removes the supplied style definition from the element's style chain.   styleDefinition     :    StyleDefinition The StyleDefinition to remove from the element.   returns     :    StyleDefinition The style definition just removed, or null if the supplied style definition is not associated with this element.   removeStyleDefinitionAt(index) CanvasElement Removes the style definition from the elements definition list at the supplied index.   index     :    int Index to be removed.   returns     :    StyleDefinition Returns the StyleDefinition just removed if successfull, null if the definition could not be removed due it it not being in this elements definition list, or index out of range.   rotatePoint(point, reverse) CanvasElement Rotates a point point on this element's parent relative to this element's rotation transformation. This is used to transform a point from the parent's coordinate plane to a child's coordinate plane or vice versa. Typically you should use translatePointFrom() or translatePointTo() rather than rotatePoint().   point     :    Object Point object {x:0, y:0};   reverse     :    boolean When true, rotates a point on the parent's plane, to the childs plane. When false, rotates a point on the childs plane, to the parents plane.   setName(name) CanvasElement Sets an arbitrary name to this element. The system does not use this value, it is for use by implementors if a way to differentiate elements is needed.   name     :    String A String to use as the element's name.   setSelectedDate(date) DatePickerButtonElement Sets the selected date of the DatePickerButton.   date     :    Date Date to set as the selected date or null for no selection.   setStyle(styleName, value) StyleDefinition Sets the stored style value for this object.   styleName     :    String String representing the style to set.   value     :    Any The value to store. This may be null or undefined. Note that a null style is different from an absent (undefined) style. A null style will terminate a style chain lookup and return null value. An undefined style will cause the system to look further up the style chain for a value. Passing undefined is the same as calling clearStyle().   setStyleDefinitions(styleDefinitions) CanvasElement Replaces the elements current style definition list. This is more effecient than removing or adding style definitions one at a time.   styleDefinitions     :    StyleDefinition May be a StyleDefinition, or an Array of StyleDefinition, including nested Arrays. Note that nested arrays will be flattened into a single array.   translateMetricsFrom(metrics, relativeFromElement) CanvasElement Translates a DrawMetrics from another element's to this element regardless of this element's transformation, depth, or position in the display hierarchy.   metrics     :    DrawMetrics Metrics to transform from the relative to this element.   relativeFromElement     :    CanvasElement The element to translate the supplied metrics too. If relativeToElement equals null or this, will return metrics the same as the supplied metrics.   returns     :    DrawMetrics Translated DrawMetrics relative to the supplied element.   translateMetricsTo(metrics, relativeToElement) CanvasElement Translates a DrawMetrics from this element's to another element regardless of this element's transformation, depth, or position in the display hierarchy.   metrics     :    DrawMetrics Metrics to transform to from this element to the supplied relative element.   relativeToElement     :    CanvasElement The element to translate the supplied metrics too. If relativeToElement equals null or this, will return metrics the same as the supplied metrics.   returns     :    DrawMetrics Translated DrawMetrics relative to the supplied element.   translatePointFrom(point, relativeFromElement) CanvasElement Translates a point from an element to this element regardless of this element's transformation, depth, or position in the display hierarchy. For example, you can call this to translate a point on the canvas to the relative point on this element.   point     :    Object Point - object containing {x:0, y:0}.   relativeFromElement     :    CanvasElement The element that the supplied point is relative too.   translatePointTo(point, relativeToElement) CanvasElement Translates a point from this element to another element regardless of this element's transformation, depth, or position in the display hierarchy. For example, you can call this to translate a point on this element to a point on the canvas.   point     :    Object Point - object containing {x:0, y:0}.   relativeToElement     :    CanvasElement The element to translate this element's point too.   Internal Members Show Inherited Member Defined By _currentSkinState     :    String SkinnableElement Read only - String representing the current state.   _height     :    Number CanvasElement Read only - This element's actual height in pixels. This is not updated immediately, only after our parent has finished its layout phase will this be valid.   _isFocused     :    boolean CanvasElement Read only - true if this element currently has focus, otherwise false.   _itemData     :    Object CanvasElement Read only - Collection item associated with this DataRenderer   _listData     :    DataListData CanvasElement Read only - List data provided by parent DataList when acting as a DataRenderer   _listSelected     :    Any CanvasElement Read only - DataRenderer selected state.   _measuredHeight     :    Number CanvasElement Read only - This element's measured height in pixels. This is not updated immediately, only after this element has finished its measure phase will this be valid.   _measuredWidth     :    Number CanvasElement Read only - This element's measured width in pixels.

This is set by elements that pop up other elements. Such as DropdownBase sets this on the pop up element.   _parent     :    CanvasElement CanvasElement Read only - This elements parent element.   _renderVisible     :    boolean CanvasElement Read only - False if any element in the parent chain is not visible. This is not updated immediately, only after redraw regions have been updated. Useful for things like "enterframe" listeners to prevent processing when not necessary.   _rotateCenterX     :    Number CanvasElement Read only - The X position relative to the element's parent this element is rotated around.

Updates date label and re-dispatches "changed" event.   elementEvent     :    ElementEvent ElementEvent to process.   _onDatePickerLayoutComplete(event) DatePickerButtonElement Event handler for pop up DatePicker "layoutcomplete". Updates the pop up size when content size is known and determines position of the pop up depending on available space.   event     :    DispatcherEvent DispatcherEvent to process.   _updateText() DatePickerButtonElement Updates the date label text via the styled DateFormatLabelFunction   Function Defined By _addChild(element) CanvasElement Adds a child element to the end of this element's child list.   element     :    CanvasElement CanvasElement to be added as a child of this element.   returns     :    CanvasElement Returns the element just added.   _addChildAt(element, index) CanvasElement Inserts a child element to this elements child list at the specified index.   element     :    CanvasElement CanvasElement to be added as a child of this element.   index     :    int The index position to insert the child in the elements child list.   returns     :    CanvasElement Returns the element just added when successfull, null if the element could not be added due to the index being out of range.   _addPopup() DropdownBaseElement Adds the pop up container to manager and registers event listeners.   returns     :    bool Returns true if the pop up was added, false if the pop up already exists.   _addStyleDefinitionAt(styleDefinition, index, isDefault) CanvasElement Inserts a style definition to this elements style definition or default definition lists. Adding style definitions to elements already attached to the display chain is expensive, for better performance add definitions before attaching the element via addElement(). Default definitions are used when styling sub components with sub styles.   styleDefinition     :    StyleDefinition StyleDefinition to be added to this elements definition list.   index     :    int The index to insert the style definition within the elements definition list.   isDefault     :    bool When true, inserts the definition into the element's default definition list.   returns     :    StyleDefinition Returns StyleDefinition just added when successfull, null if the StyleDefinition could not be added due to the index being out of range or other error.   _applySubStylesToElement(styleName, elementToApply) [Override] CanvasElement Convienence function for setting sub styles of sub components. Applies appropriate sub styling from this element to the supplied elements definition and default definition style lists. You should call this on sub components from within the _doStylesUpdated() function when the associated sub style changes.   styleName     :    String String representing the sub style to apply.   elementToApply     :    CanvasElement The sub component element to apply sub styles.   _changeState(state) SkinnableElement Called when the element changes skin state. Do not call this function directly. You may override this if you need to make additional changes to your component when the skin state changes (such as updating a label color).   state     :    String The skin state that this element is changing too.   returns     :    boolean Returns true if the element state has actually changed, false if it is the same state. Subclasses can check what this base function returns before making additional changes for better performance.   _createLabel() ButtonElement Creates the Button's label instance when Text style is not null or empty.   returns     :    LabelElement New LabelElement instance   _createPopup() DropdownBaseElement Stub for creating the pop up element to be added to the pop up container. Override this and return a new CanvasElement instance to be used as the pop up.   returns     :    CanvasElement New pop up instance.   _doLayout(paddingMetrics) CanvasElement Lifecycle method for custom component development. Never call this function directly. The system calls this function in response to changes that effect layout or elements being added to the display hierarchy. Override this function to layout its children. You should call layout functions such as _setActualPosition() and _setActualSize() on child elements from within this function. Sometimes you may need to add/remove additional elements during layout such as when a Datagrid or Viewport adds/removes scroll bars. Keep in mind that adding/removing elements automatically re-invalidates layout, so its best to bail out and wait for the next layout pass for best performance under this scenario.   paddingMetrics     :    DrawMetrics Contains metrics to use after considering the element's padding. Simply a convienence as padding typically effects layout (but not always) depending on the component. Use any supporting functions such as _getBorderMetrics() that are needed to layout the element.   _doMeasure(padWidth, padHeight) CanvasElement Lifecycle method for custom component development. Never call this function directly. The system calls this function in response to changes that effect measurement or elements being added to the display hierarchy. Override this function to calculate the measured size of the element based on its styling, children, etc. You should set the elements measured size by calling _setMeasuredSize() from within this function.   padWidth     :    Number Simply a convienence as padding typically effects measurement (but not always) depending on the component. Use any supporting functions such as _getBorderThickness that are needed to measure the element.   padHeight     :    Number Simply a convienence as padding typically effects measurement (but not always) depending on the component. Use any supporting functions such as _getBorderThickness that are needed to measure the element.   _doRender() CanvasElement Lifecycle method for custom component development. Never call this function directly. The system calls this function in response to changes that effect rendering or elements being added to the display hierarchy. Override this function to render the element. Keep in mind that any child elements are rendered on top of this element. This function is typically not needed unless rendering a very primitive object such as a custom skin or a display object that cannot be handled via a BackgroundShape class and/or _fillBackground() function. Most advanced objects should use skins and other means to render themselves. CanvasElement draws its background and border via supplied shape and gradient settings.   _doStylesUpdated(stylesMap) CanvasElement Lifecycle method for custom component development. Never call this function directly. The system calls this function in response to style changes or elements being added to the display hierarchy. Override this function to handle style changes to the element. Style changes may impact other styles, event listeners, layout, measurement, rendering, etc. You should call appropriate _invalidate() method per style. Note that style handling should not be dependent on the *current* state of a style. This function should be able to run repeatedly with the same values. An example of when this may happen is if an element is temporarily removed from the display hierarchy then added back. Whenever an element is added all of its styles are invalidated. This is necessary as when an element is *not* part of the display chain style changes are not tracked. So when an element is added there is no way to know which styles may have changed hence all of them are invalidated.   stylesMap     :    Object An Object map containing all the style names that have been updated. Map contains entries {styleName:true}. Elements should typically check this map before assuming a style has changed for performance reasons. You should always call the base method. If you wish to override the style handling behavior of a specific style, you can simply delete it from the map before passing it to the base function.   _drawBackgroundShape(ctx, borderMetrics) CanvasElement Used to draw the path to the Canvas2DContext that is to be used to render the focus ring, fill the background, and draw the border. You should never need to explicitly call this. The system calls this during render phase. Typically you should use the BackgroundShape style for this, but may override it under more complex scenarios.   ctx     :    Canvas2DContext Canvas2DContext to draw the background shape path.   borderMetrics     :    DrawMetrics The DrawMetrics containing x,y,width,height used to draw the background. These metrics should be the same as the ones used to stroke a solid border.   _drawBorder(ctx, borderMetrics) CanvasElement Used to render the elements border according to the element's style settings. You should never need to explicitly call this. The system calls this during the render phase. You may override if you need to do a more complex border. The border is rendered last, on top of the focus ring and background fill.   ctx     :    Canvas2DContext Canvas2DContext to render the border.   borderMetrics     :    DrawMetrics The DrawMetrics containing x,y,width,height used to draw the background. These metrics should be the same as the ones used to stroke a solid border.   _drawFocusRing(ctx, borderMetrics) CanvasElement Used to draw the focus ring when a tab-able element gains focus due to a tab stop per the elements styles.

Focus ring is drawn *outside* the elements bounding box. Focus ring is rendered before the background and border.   ctx     :    Canvas2DContext Canvas2DContext to render the focus ring.   borderMetrics     :    DrawMetrics The DrawMetrics containing x,y,width,height used to draw the background. These metrics should be the same as the ones used to stroke a solid border.   _fillBackground(ctx, borderMetrics) CanvasElement Used to fill the elements background shape according to the element's BackgroundShape and BackgroundFill styles. You should never need to explicitly call this. The system calls this during the render phase. You may override if you need to do a more complex background fill. The background fill is rendered after the focus ring and before the border.   ctx     :    Canvas2DContext Canvas2DContext to fill the background shape.   borderMetrics     :    DrawMetrics The DrawMetrics containing x,y,width,height used to draw the background. These metrics should be the same as the ones used to stroke a solid border.   _getBorderMetrics() CanvasElement Helper function that returns a DrawMetrics object whose bounding area is inside this elements border.   returns     :    DrawMetrics Returns DrawMetrics that define a bounding area inside this elements border.   _getBorderThickness() CanvasElement Helper function that returns the elements border thickness per its applied styles.   returns     :    Number The elements border thickness.   _getChildAt(index) CanvasElement Gets the child element at the supplied index.   index     :    int Index of child element to return;   returns     :    CanvasElement The element at the supplied index, or null if index is out of range.   _getChildIndex(element) CanvasElement Returns the index of the supplied child element.   element     :    CanvasElement Child element to return the index.   returns     :    int Returns the child index or -1 if the element is not a child of this element.   _getClassStyle(styleName) StyleableBase Gets the default style value for the supplied style name specified on this classes StyleDefault map.

This is just a helper to gather and format the styles for the canvas context.   returns     :    String String to be applied to the canvas contex's font. "bold 14px Arial".   _getGraphicsCtx() CanvasElement Returns the canvas context used when rendering this element. This should typically only be called from within the element's _doRender() phase, and only if you intend to actually draw. Calling this will impact the canvas redraw regions.   returns     :    Canvas2DContext Canvas context used when rendering this element.   _getInstanceStyle(styleName) StyleableBase Gets the assigned style value for the supplied style name specified.   styleName     :    String String representing the style to return.   returns     :    Any Returns the associated style value or undefined if none specified.   _getNumChildren() CanvasElement Gets this elements number of children.   returns     :    int The number of child elements.   _getNumStyleDefinitions(isDefault) CanvasElement Gets the number of style definitions or default definitions associated with this element.   isDefault     :    bool When true, returns the number of default definitions.   returns     :    int The number of style definitions.   _getOpenedTweenValue() DropdownBaseElement Returns value to be used for the pop up's fully open position.

Override this if you need to pass additional styles to custom skins. You should include all the styles provided in the default SkinnableElement style map.   returns     :    Object Return a style proxy map to be applied to this element to all skins. Formatted as: MyProxyMap = Object.create(null); MyProxyMap.StyleName1 = true; MyProxyMap.StyleName2 = true;   _getStyleDefinitionAt(index, isDefault) CanvasElement Gets the style definition or default definition at the supplied zero base index.   index     :    int Index of the style definition to return;   isDefault     :    bool When true, returns the default definition at the supplied index.   returns     :    StyleDefinition The style defenition at the supplied index, or null if index is out of range.   _getStyledOrMeasuredHeight() CanvasElement Helper function that returns this elements styled height, or measured height if no style is set.

Needed by subclasses for positioning the pop up element.   returns     :    boolean True if the open/close tween is running, otherwise false.   _invalidateLayout() CanvasElement Invalidates the elements child layout and causes the system to invoke doLayout() on the next layout phase. The system calls this automatically for all existing components, this is only necessary for custom component development. This should only be called when a change is made to the element that will impact its layout. Such as property changes or from within the elements doStylesUpdated() when a style change impacts the element's layout (such as Padding). On rare occasions you may need to re-invalidate layout from within the doLayout() function. An example is when a DataList adds a new DataRenderer it re-invalidates layout to allow the renderer to measure before continuing layout. Do not override this function.   _invalidateMeasure() CanvasElement Invalidates the element's measured sizes and causes the system to invoke doMeasure() on the next measure phase. The system calls this automatically for all existing components, this is only necessary for custom component development. This should only be called when a change is made to the element that will impact its measurement. Such as property changes or from within the elements doStylesUpdated() when a style change impacts the elements measurement (such as Padding). On rare occasions you may need to re-invalidate measurement from within the doMeasure() function (such as wrapping text). This will cause a 2nd measurement pass for that element which is valid (but expensive). Do not override this function.   _invalidateRender() CanvasElement Invalidates the elements child render and causes the system to invoke doRender() on the next render phase. The system calls this automatically for all existing components, this is only necessary for custom component development. This should only be called when a change is made to the element that will impact its rendering. Such as property changes or from within the elements doStylesUpdated() when a style change impacts the element's rendering (such as BackgroundFill). Do not override this function.   _invalidateStyle(styleName) CanvasElement Invalidates the supplied style and causes the system to invoke the _doStylesChanged() function. This should never concievably be called and is exclusively handled by the system. This is the starting point for the element lifecycle. If you're program is dependent on _doStylesChanged() when no styles have actually changed, you might have a design issue. Do not override this function.   styleName     :    String String representing the style to be invalidated.   _layoutDatePickerPopup() DatePickerButtonElement Sizes and positions the DatePicker pop up.   _onButtonClick(elementMouseEvent) ButtonElement Event handler for "click" event.

Updates the Button skin state. Overriding this is more efficient than adding an additional "rollover" event listener.   elementEvent     :    ElementEvent The ElementEvent to process.   _onCanvasElementAdded(addedRemovedEvent) CanvasElement Invoked when the element is added to the canvas. Every CanvasElement already adds its own "added" event listener so overriding this is identical but more efficient than adding your own "added" event listener. You should *always* call the base class function.   addedRemovedEvent     :    AddedRemovedEvent The AddedRemovedEvent to process.   _onCanvasElementRemoved(addedRemovedEvent) CanvasElement Invoked when the element is removed to the canvas. Every CanvasElement already adds its own "removed" event listener so overriding this is identical but more efficient than adding your own "removed" event listener.

Default definitions are used when styling sub components with sub styles.   index     :    int Index to be removed.   isDefault     :    bool When true, removes the definition from the element's default definition list.   returns     :    StyleDefinition Returns the StyleDefinition just removed if successfull, null if the definition could not be removed due it it not being in this elements definition list, or index out of range.   _setActualPosition(x, y) CanvasElement Sets the elements position within its parent. Note that if the element is transformed or rotated, this sets the elements position within its transformed plane. If you wish to position a transformed element relative to its parents coordinate plane, use _setRelativePosition(). This should typically only be called from within the parents layout phase.   x     :    int The X position to move the element.   y     :    int The Y position to move the element.   _setActualRotation(degrees, centerX, centerY) CanvasElement Sets this elements rotation degrees and rotation point relative to its parent.

Override this function to make any changes to the DataRenderer per the selection state. Update any styles, states, add/remove children, call any necessary _invalidate() functions, etc.   selectedData     :    Any Selected data, differs per container.   _setRelativePosition(x, y, relativeToElement) CanvasElement Sets the elements position relative to a supplied element regardless of this element's transformation, depth, or position in the display hierarchy or relation to the supplied relativeToElement. This should typically only be called during the parent element's layout phase. Setting relativeToElement to null has an identical effect to calling _setActualPosition(). This is used by some containers to position the element relative to a parent's coordinate plane rather than the child's transformed plane.   x     :    Number The relative X position to move this element's position.   y     :    Number The relative Y position to move this element's position.   relativeToElement     :    CanvasElement The CanvasElement to move this element relative too.   _setStyleDefinitions(styleDefinitions, isDefault, styleNamesChangedMap) CanvasElement Replaces the elements current style definition or default definition lists. This is more effecient than removing or adding style definitions one at a time. Default definitions are used when styling sub components with sub styles.   styleDefinitions     :    StyleDefinition May be a StyleDefinition, or an Array of StyleDefinition   isDefault     :    bool When true, replaces the default definition list.   styleNamesChangedMap     :    Object Optional - A empty map object - Object.create(null) to populate style changes due to swapping definitions while this element is attached to the display chain. When specified (not null), does not automatically invoke style changed events.   _setStyleProxy(styleProxy) CanvasElement Sets the element which is to proxy styles to this element. See getStyle() and StyleProxy. This should be set prior to added this element to the display hierarchy via addElement() or _addChild().   styleProxy     :    StyleProxy The StyleProxy element wrapper to use to proxy styles from the proxy element to this element.   _updateSkinClass(state) SkinnableElement Updates the skin class for the skin of the provided state. Subclasses should call this within their _doStylesUpdated() when skin style class changes.   state     :    String The state for which to update the skin class.   _updateSkinStyleDefinitions(state) SkinnableElement Updates the StyleDefinition for the skin of the provided state. Subclasses should call this within their _doStylesUpdated() when skin style definitions change.   state     :    String The state for which to update the StyleDefinition.   _updateState() ButtonElement Called in response to mouse events, and when the Button is added to the display hierarchy (if mouse is enabled). Updates the Button skin state.   _updateText() DatePickerButtonElement Updates the date label text via the styled DateFormatLabelFunction   _updateTextColor() ButtonElement Updates the text color in response to state changes.   _updateTweenPosition(value) DropdownBaseElement Stub for updating the popup when the tween value changes. Override this to adjust the popup during the open/close tween.   value     :    Number Current tween value.
