That code (although I didn't test it),
seems fine, and should work if you are using a recent gtk version.
If not, that will only work if accessibility is enabled.
Anyway, FWIW, we plan to deprecate those methods at some moment of
the future:

If you want to track when the focus change, you can also add a
global event, and filter state-change:focus events.

I tried to make my first steps in ATK, but I can't understand
what I'm doing wrong.
Here is my Vala code:
using GLib;
using Atk;
using Gtk;
void _my_focus_tracker (Atk.Object object) {
stdout.printf ("Tracked!\n");
}
int main (string[] args) {
Gtk.init (ref args);
Util.add_focus_tracker (_my_focus_tracker);
Gtk.Window window1 = new Gtk.Window ();
window1.show ();
Gtk.Window window2 = new Gtk.Window ();
window2.show ();
Gtk.main ();
return 0;
}
add_docus_tracker doesn't call _my_focus_tracker when focus get
changed.
I know that most of you may not know Vala, so here is part of
the C generated/equated code:
void _my_focus_tracker (AtkObject* object) {
FILE* _tmp0_;
g_return_if_fail (object != NULL);
_tmp0_ = stdout;
fprintf (_tmp0_, "Tracked!\n");
}
gint _vala_main (gchar** args, int args_length1) {
gint result = 0;
GtkWindow* _tmp0_;
GtkWindow* _tmp1_;
GtkWindow* window1;
GtkWindow* _tmp2_;
GtkWindow* _tmp3_;
GtkWindow* window2;
gtk_init (&args_length1, &args);
atk_add_focus_tracker
(_my_focus_tracker_atk_event_listener);
_tmp0_ = (GtkWindow*) gtk_window_new (GTK_WINDOW_TOPLEVEL);
_tmp1_ = g_object_ref_sink (_tmp0_);
window1 = _tmp1_;
gtk_widget_show ((GtkWidget*) window1);
_tmp2_ = (GtkWindow*) gtk_window_new (GTK_WINDOW_TOPLEVEL);
_tmp3_ = g_object_ref_sink (_tmp2_);
window2 = _tmp3_;
gtk_widget_show ((GtkWidget*) window2);
gtk_main ();
result = 0;
_g_object_unref0 (window2);
_g_object_unref0 (window1);
return result;
}
int main (int argc, char ** argv) {
g_type_init ();
return _vala_main (argv, argc);
}
For some reason, even when GLib main loop is running, no focus
change detection between the two windows.
Have I miss something? I think I haven't initialize something or
forgot to active watcher...
Hope for your reply
Tal
