    if ( bitmap.depth() != 1 || mask.depth() != 1 ||
	 bitmap.size() != mask.size() ) {
#if defined(QT_CHECK_NULL)
	qWarning( "QCursor: Cannot create bitmap cursor; invalid bitmap(s)" );
#endif
	QCursor *c = &cursorTable[arrowCursorIdx];
	c->data->ref();
	data = c->data;
	return;
    }
    data = new QCursorData;
    Q_CHECK_PTR( data );
    data->bm  = new QBitmap( bitmap );
    data->bmm = new QBitmap( mask );

    update(); // Xcursor's backward compatibility hack needs the cursor to be created
              // right after the bitmaps are created and filled with data
