TcxCustomShellListView.OnExecuteItem Event

Occurs before the default associated program is launched for the file shell item activated by pressing the Enter key or by double-clicking the mouse.

Declaration

property OnExecuteItem: TcxShellExecuteItemEvent read; write;

Remarks

The APIDL parameter identifies the shell item being activated by pressing the Enter key or by double-clicking the mouse. To convert the APIDL parameter value to a readable string, use the GetPIDLName function.

Set the AHandled parameter to True, to prevent launching the default associated program for the activated file shell item.

The following code example demonstrates how to prohibit launching the default associated program for .BMP files.

procedure TForm1.cxShellListView1ExecuteItem(Sender: TObject;
  APIDL: PItemIDList; var AHandled: Boolean);
begin
  AHandled := Pos('.bmp', GetPIDLDisplayName(APIDL, True)) = Length(GetPIDLDisplayName(APIDL, True)) - 3;
end;

Note

The OnExecuteItem event is fired only when the AutoExecute property is set to True.
