RE: Atk focus change capture fail. Why?

Yes. I'm talking about my process(X) that can read ATK windows of all processes A,B,C,...N
Generally, cross processing ATK with no GtkPlug. Is this possible?

I guess it's possible, since ATK based tools don't have to be plugged to other applications.
E.G. Orca reader can read ATK windows of other processes.
When I tried to listen to global listener, only in-process windows are hooked.

Hope I've bean more clear now.

What do you mean of "how to get focus changes of all windows, not just in the same process"?

Do you mean that you have two applications (ie: gedit and gcalculator) and you want to know when one of the windows get the focus?

I found the problem I had:
The windows I showed up are blank windows. If I added them some widgets they work fine.
Also, I can't find in Google how to get focus change of all windows, not just in the same process.
Is this possible?

Thanks

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
