GTK2: hint not showing for disabled control

[zoltanleo]

Hi all.

I found a slightly strange behavior of the hint property for a disabled control. For win32/Сocoa widgetsets hint is displayed, for gtk2 it is not displayed.

Code: Pascal  [Select][+][-]

1. procedure TForm1.FormCreate(Sender: TObject);
2. begin
3.   with btnEnabled do
4.   begin
5.     ShowHint:= True;
6.     Enabled:= True;
7.     Hint:= 'This is an enabled control';
8.   end;
9.  
10.   with btnDisabled do
11.   begin
12.     ShowHint:= True;
13.     Enabled:= False;
14.     Hint:= 'This is disabled control';
15.   end;
16. end;

What behavior is considered a bug?
