onlyonekgx的挺好!
不过以下代码你也可以参考一下,不光是显示toolbar的button!!
private
{ Private declarations }
procedure ShowHint(Sender: TObject);
procedure TMainForm.FormCreate(Sender: TObject);
begin
Application.OnHint := ShowHint;
end;
procedure TMainForm.ShowHint(Sender: TObject);
begin
StatusBar.SimpleText := Application.Hint;
end;
