I think it does work, but the color on the GtkHScale does not really change, only after changing the value at the slider, as before. I added (hint from the gtk mailing list) this: gtk_widget_queue_draw(GTK_WIDGET(scales[0])); while (gtk_events_pending()=gtk_true) do gtk_main_iteration (); to process all pending draw event afterwards, but no luck. :( Must be a bug or some plan I do not get. Has anyone ever managed to change a GtkHScales color on the fly? I can do it at startup from the ressource file, but changing afterwards is not possible. But it does work when i minimize the window and restore it! And it is colorizing the whole bar, not only the places where the slider steps ... Any further hints? ___ fpc-pascal maillist - [EMAIL PROTECTED] http://lists.freepascal.org/mailman/listinfo/fpc-pascal

A testing program written in C to be sure it's not a fault of the pascal binding teached me that. Now I'll try a forced resize and hope to get no flickering.

I'm really, really sad to write this: It was the theme engine. Although apparently unistalled a library and activated definition im my .gtkrc were still there. This was very stupid, sorry.
