Dear Experts,

I have used the ActionList component for my MainMenu. So my MainMenu is working
great without any code. Event the property Hint is automaticly filled in of each menu-item.
I have also a statusbar. What do I have to do that when i select a menu-item that the
hint of the menu-item will be showned in my statusbar.

Greetings Pk

    protected

      procedure AdvancedDrawItem(ACanvas: TCanvas; ARect: TRect; State: TOwnerDrawState; TopLevel: Boolean); override;

    public

      property StatusBar: TStatusBar read FStatusBar write FStatusBar;

  end;

What exactly are you looking for? I assumed from your original question that you wanted the selected menu item's hint to be shown on your status bar.

I am also unsure as do what you mean on how it can be done easier? It's a pretty simple solution(as simple as I could tell) because there is no event for when your item is selected directly.

Maybe you could help me help you?

I think this is a way to start:

private
  procedure MyHint(Sender: TObject);
end;
 

implementation

 {....}

procedure TForm1.FormCreate(Sender: TObject);
begin
  Application.OnHint := MyHint;
  ShowHint           := True;
  Button1.Hint       := 'normal yellow hint|Text in Statusbar';
  Button2.Hint       := 'only yellow hint|';
  Button3.Hint       := '|text only in statusbar';
  Edit1.Hint         := 'same text';
end;

procedure TForm1.MyHint(Sender: TObject);
begin
  StatusBar1.SimpleText := Application.Hint;
end;

But how to tell the system to use the proprty hint of every menu-item

I guess you could use the message WM_MENUSELECT to catch the event as in: http://delphi.about.com/od/vclusing/a/menuitemhints.htm

But I still think my way is cleaner.
