Ok, I read that on GTK, middle mouse button is responsible for jump to position. So I am trying to simulate it:
procedure TForm1.TrackBar1Click(Sender: TObject); begin PostMessage(TrackBar1.Handle, LM_MBUTTONDOWN, 0, 0); //TrackBar1.Perform(LM_MBUTTONDOWN,0,0); end; But it doesn't work. Here is some python solution but I don't understand it: https://mail.gnome.org/archives/gtk-list/2011-November/msg00032.html -- _______________________________________________ Lazarus mailing list [email protected] http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
