Something else is broken :-( maybe you're trying to warp the focus to a
widget that's not been built properly yet?
This works for me:
--
#include
int
main (int argc, char *argv[])
{
GtkWidget *window;
GtkWidget *vbox;
GtkWidget *button1;
GtkWidget *button2;
gtk_init (&argc, &argv);
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
gtk_window_set_policy (GTK_WINDOW (window), FALSE, TRUE, FALSE);
vbox = gtk_vbox_new (FALSE, 0);
gtk_container_add (GTK_CONTAINER (window), vbox);
button1 = gtk_button_new_with_label ("foo");
gtk_box_pack_start (GTK_BOX (vbox), button1, TRUE, TRUE, 0);
button2 = gtk_button_new_with_label ("bar");
gtk_box_pack_start (GTK_BOX (vbox), button2, TRUE, TRUE, 0);
gtk_signal_connect_object (GTK_OBJECT (button1), "clicked",
GTK_SIGNAL_FUNC (gtk_widget_grab_focus),
GTK_OBJECT (button2));
gtk_signal_connect_object (GTK_OBJECT (button2), "clicked",
GTK_SIGNAL_FUNC (gtk_widget_grab_focus),
GTK_OBJECT (button1));
gtk_widget_show_all (window);
gtk_main ();
return 0;
}

I've got Segmentation Fault :_(
My function to change active widget looks like:
void
przejdz (char *element, GtkWidget * mw)
{
// Change active widget to widget with name element
GtkWidget *w;
if ((w = lookup_widget (mw, element)) == NULL)
return;
gtk_widget_grab_focus (w);
return;
}
and for example:
przejdz("entry3",main_window);
make 1 or 2 seconds without reaction (coursor doesn't) change it's position
(program freezes) and after this time window closes with Segmentation Fault
message.

There are a bunch of freeze/thaw functions in gtk+-1.2, but they don't work very well and have all been removed for gtk2 (I think). gtk2 is much more sensible about painting the screen and you don't need this trick.

RE: 2 (simple?) questions
Krzysztof, you want to use something with *freeze*, do things in memory and then *thaw* your widget/application. I have used such things like gtk_text_freeze[thaw] or with clists... A complete list of these functions should be in the gtkwidget.h (the reply posted earlier). For the second one I have no idea. Regards, Martin >> >> > 1.

If you are not familiar with these files you can also take a look in the gtk+-2.0-reference manual at .
