TControlCursor (Delphi)

Description

This example shows how to add custom cursors to an application. The following code makes this cursor available to the application through the constant crMyCursor, and sets it as the global cursor to the application.

Code

var
  bmpMask : TBitmap;
  bmpColor : TBitmap;
  iconInfo : TIconInfo;
const
  crMyCursor = 5;

procedure TForm1.Button2Click(Sender: TObject);
begin
  bmpMask := TBitmap.Create;
  bmpColor := TBitmap.Create;

  bmpMask.LoadFromFile('SquareMask.bmp');
  bmpColor.LoadFromFile('Square.bmp');

  with iconInfo do
  begin
    fIcon := false;
    xHotspot := 15;
    yHotspot := 15;
    hbmMask := bmpMask.Handle;
    hbmColor := bmpColor.Handle;
  end;

  Screen.Cursors[crMyCursor] := CreateIconIndirect(iconInfo);
  
  Screen.Cursor := crMyCursor;

  bmpMask.Free;
  bmpColor.Free;
end;

procedure TForm1.FormDestroy(Sender: TObject);
begin
  DestroyIcon(Screen.Cursors[crMyCursor]);
end;
