DN_DRAWDLGITEM

ID of the dialog item that is about to be drawn.

Pointer to the FarDialogItem structure for the item to be drawn.

If the dialog callback function returns FALSE, the item will not be drawn.

Control	Description
All	All dialog items

A dialog item of the DI_USERCONTROL type, but not any other dialog item, can be prepared in advance in a virtual buffer. FAR Manager does not copy the contents of this buffer to its internal structures, so as a response to the DN_DRAWDLGITEM event it is sufficient to change only the state of the virtual buffer:

case DN_DRAWDLGITEM:
  CHAR_INFO *VBuf=((struct FarDialogItem*)Param2)->Param.VBuf;
  for (I=0; I < 256; I++)
  {
    VBuf[I].Char.AsciiChar = DecodeTable[I];
    VBuf[I].Attributes = Color;
  }
  return TRUE;
