Hi, gtk_widget_grab_focus() works for me, what problem were
you having
with it?
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.

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 gtk/gtk.h
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;
}

Re: 2 (simple?) questions
Hi! I have 2 questions. Perhaps someone knows solutions? 1. Is it possible to freeze display (and do something only in memory) and unfreeze after program do what I want? I want to freeze main_window and in this time I wanna show/hide widgets and add elements for lists etc. It takes much more time (and looks not nice) when everytking is visible. 2. How can I change active widget? Tab key only can change coursor position to the next widget. I want to change active widget from source level. (It depends what user of program will do). I know that it is not possible for some widgets (ie.labels, etc). For both of these questions you sould look in gtk+-2.0/gtk/gtkwidget.h in your include directory. There you should find answers. If you are not familiar with these files you can also take a look in the gtk+-2.0-reference manual at www.gtk.org.
