Create your own hints

If you don't quite like the way how Delphi's default hints look like, you can use THintWindow component to create your own customized hint window. Here's an example:

var
  h : THintWindow;
  r : TRect;
begin
  with r do
  begin
    //
    // set the position and size
    // of the hint window
    //
    left   :=  10;
    top    :=  50;
    right  := 200;
    bottom := 100;
  end;
  h := THintWindow.Create( Self );
  with h do
  begin
    //
    // set the background color
    //
    Color := clRed;

    ActivateHint( r, 'hi there!' );

    //
    // perform your tasks here
    // before closing the hint window
    //
    MessageBox( 0,
      'Press any key to close the '
      + 'hint window',
      'THintWindow',
      MB_OK );
      
    ReleaseHandle;
    Free;
  end;
end;
