Hints: color and timing; more than one line

 
Hints -- the little windows that are shown when moving the mouse cursor over a component or a menu item -- can be customized. You can change their color, their timing, and even show more than one line of text.

• Color and timing of Hints
• More lines in a Hint

In the OnCreate event handler of the main form of your application, write this code:

procedure TForm1.FormCreate(Sender: TObject);
begin
  Application.HintColor := clAqua;   // color of your choice
  Application.HintPause := 250;      // 250 mSec before hint is shown
  Application.HintHidePause := 3000; // hint disappears after 3 secs
end;

If you want to display more than one line in the Hint of a component, for example Button1:

- In the Object Inspector, don't put anything in Button1's Hint property.
- Don't forget to set its ShowHint property to TRUE.

In the FormCreate event handler of the form that contains Button1, add this code:

Button1.Hint := 'First line'  + #13 + 'Second line' + #13 + 'Third line';         
  
 // ...add more lines as desired...
