Quickly sets both horizontalGap and verticalGap to the same value. The gap getter always returns the value of horizontalGap, but the value of verticalGap may be different.

If the total row width is less than the bounds, the items in the row can be aligned horizontally.

The horizontal space, in pixels, between tiles.

Quickly sets all padding properties to the same value. The padding getter always returns the value of paddingTop, but the other padding values may be different.

The space, in pixels, below the items.

The space, in pixels, to the left of the items.

The space, in pixels, to the right of the items.

The space, in pixels, above of items.

If the total combined height of the rows is larger than the height of the view port, the layout will be split into pages where each page is filled with the maximum number of rows that may be displayed without cutting off any items.

If the item's width is less than the tile bounds, the position of the item can be aligned horizontally.

If an item's height is less than the tile bounds, the position of the item can be aligned vertically.

The height, in pixels, of a "typical" item that is used to virtually fill in blanks for the layout. This value is usually set by a component that is using the layout, such as a List or a ScrollContainer. In most cases, unless you are creating a new custom component that supports layouts, you should never need to set this value.

Determines if the tiles must be square or if their width and height may have different values.

Determines if virtual layout can be used. Some components don't support virtual layouts. In those cases, the virtual layout options will be ignored.

If the total column height is less than the bounds, the items in the column can be aligned vertically.

The vertical space, in pixels, between tiles.

Constructor.

Using the item dimensions, calculates a scroll position that will ensure that the item at a given index will be visible within the specified bounds.

Parameters

Determines which indices are visible with the specified view port bounds and scroll position. Indices that aren't returned are typically not displayed and can be replaced virtually.

Parameters

Positions (and possibly resizes) the supplied items within the optional bounds argument. If no bounds are specified, the layout algorithm will assume that the bounds start a 0,0 and have unbounded dimensions. Returns the actual bounds of the content, which may be different than the specified bounds.

Note: The items are not absolutely restricted to appear only within the bounds. The bounds can affect positioning, but the algorithm may very well ignore them completely.

If a layout implementation needs to access accurate width and height values from items that are of type IFeathersControl, it must call validate() manually. For performance reasons, the container that is the parent of the items will not call validate() before passing the items to a layout implementation. Meeting this requirement may be as simple as looping through the items at the beginning of layout() and validating all items that are Feathers UI controls:

         const itemCount:int = items.length;
         for(var i:int = 0; i < itemCount; i++)
         {
             var item:IFeathersControl = items[i] as IFeathersControl;
             if(item)
             {
                 item.validate();
             }
         }

Parameters

Using the typical item bounds and suggested bounds, returns a set of calculated dimensions for the view port.

Parameters

If the total item width is smaller than the width of the bounds, the items will be aligned to the center.

If the total item width is smaller than the width of the bounds, the items will be aligned to the left.

If the total item width is smaller than the width of the bounds, the items will be aligned to the right.

The items will be positioned in pages horizontally from left to right.

The items will not be paged. In other words, they will be positioned in a continuous set of rows without gaps.

The items will be positioned in pages vertically from top to bottom.

If an item width is smaller than the width of a tile, the item will be aligned to the center of the tile.

The item will be resized to fit the width of the tile.

If an item width is smaller than the width of a tile, the item will be aligned to the left edge of the tile.

If an item width is smaller than the width of a tile, the item will be aligned to the right edge of the tile.

If an item height is smaller than the height of a tile, the item will be aligned to the bottom edge of the tile.

The item will be resized to fit the height of the tile.

If an item height is smaller than the height of a tile, the item will be aligned to the middle of the tile.

If an item height is smaller than the height of a tile, the item will be aligned to the top edge of the tile.

If the total item height is smaller than the height of the bounds, the items will be aligned to the bottom.

If the total item height is smaller than the height of the bounds, the items will be aligned to the middle.

If the total item height is smaller than the height of the bounds, the items will be aligned to the top.
