DN_DRAWDLGITEM

Events | Dialog API
The DN_DRAWDLGITEM event is sent to the dialog callback function before a dialog item is drawn.

Param1

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

Param2

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

Return

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

Controls

ControlDescription
All All dialog items

Remarks

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;
