Tab or Alt-Tab? If Alt+Tab, is there any way I can configure an LIRC
key to be an Alt+Tab?

I tried this in my app with still no cursor key (via LIRC)
functionality in my GtkCList.
So I went a step further and hooked up callbacks to the focus_in_event
and key_press_event signals to see if my GtkCList was getting focus
and if my LIRC "keystrokes" were making it to the GtkCList, and they
all are. Here is the signal registration and my callback for the
key_press_event:
gtk_signal_connect(GTK_OBJECT (programList), "key_press_event",
GTK_SIGNAL_FUNC (on_programList_key_press_event),
NULL);
gboolean
on_programList_key_press_event (GtkWidget *widget,
GdkEventKey *event,
gpointer user_data) {
fprintf(stderr, "key_press (%x) for widget %s\n", event->keyval,
gtk_widget_get_name(widget));
return TRUE;
}
And when I run my application on directfb I get the following output
from pressing the up and down (respectively) keys on my remote:
# /usr/src/openpvr/chooser/src/chooser

Gdk-DirectFB-Message: gdk_pango_context_get assumes a screen resolution of 72 dpi
focus_in for widget GtkCList
key_press (ff52) for widget GtkCList
key_press (ff54) for widget GtkCList
So it seems that the GtkCList (programList) is getting the keypress
events and they are the right ones (from
/usr/include/gtk-2.0/gdk/gdkkeysyms.h):
#define GDK_Up 0xFF52
#define GDK_Down 0xFF54
so I am at a loss as to why my GtkCList is not reacting to the keys
when I remove the signal handler for key_press_event.
Any more ideas? Any further tests I can do?
