class CGXBitmapButton: public CGXControl

The CGXBitmapButton class implements a bitmap button that can be used in grid cells.

To display bitmaps in cells, you need to register a CGXBitmapButton object for each different bitmap button. When the object is created you should pass the resource ids of the bitmap to the CGXBitmapButton constructor. CGXBitmapButton can be used as a pushbutton. You can specify bitmaps for normal state, pressed state and focus-state.

When the user clicks the bitmap, the control's OnClickedButton method is called. The default behavior of OnClickedButton is to call CGXGridCore::OnClickedButtonRowCol.

To process this event, you can either subclass CGXBitmapButton and override the control’s OnClickedButton method, or simply override OnClickedButtonRowCol in your CGXGridCore-derived class.

The following steps are necessary to display bitmaps in cells:

1. You need to add a string resource:

Example:

// Your .RC - file:

STRINGTABLE DISCARDABLE
BEGIN
      IDS_CTRL_BITMAP        "Welcome bitmap"
END

2. In OnInitialUpdate, you should pass a new instance of the object together with the string resource id to RegisterControl.

void CGridSampleView::OnInitialUpdate( )
{
   ...

   RegisterControl(IDS_CTRL_BITMAP,
      new CGXBitmapButton(this, IDB_WELCOME));
}

3. Now, you can apply the bitmap to any cell in the grid with CGXStyle::SetControl.

// Display the welcome bitmap
SetStyleRange(CGXRange( 3, 2 ), CGXStyle( )
   .SetControl( IDS_CTRL_BITMAP ));
