TCustomGrid.GetImageForCheckBox procedure

Declaration

procedure GetImageForCheckBox(const aCol: Integer; const aRow: Integer; 
 CheckBoxView: TCheckBoxState; 
 var ImageList: TCustomImageList; 
 var ImageIndex: TImageIndex; 
 var Bitmap: TBitmap); virtual

Description

GetImageForCheckBox signals the OnUserCheckboxBitmap event handler (when assigned) to get a bitmap used for the check box state. If a valid TBitmap instance is not assigned in the event handler, the OnUserCheckBoxImage event handler is signalled (when assigned) to get the TImageList, TBitmap, and ImageIndex used for the purpose.

GetImageForCheckBox is used in the implementation of the DrawGridCheckboxBitmaps and DrawCellText methods in TCustomGrid.
