I have a problem with gdk_window_add_filter(NULL, &func, NULL) which is supposed to catch all events globally. I have done a little program in Gtk2 to test this and it only reacts on modifier keys and mouse clicks. And even with this, I am not able to see the keycode, I only see the word "seen" in my terminal, which indicates that my callback was called. I would like to see other keypresses because I am trying to implement a special keys controller for xmms (special cd-player-like keys on my laptop which generate events in xev)...
Here is the source :
--8<------------------------------------------------------------- #include <stdio.h> #include <gtk/gtk.h>
GdkFilterReturn kbd_filter (GdkXEvent *gdk_xevent, GdkEvent *event, gpointer data)
{
GdkEventType type;
GdkEventKey *key;
printf("seen\n");
type = event->type; if (type == GDK_KEY_RELEASE) {
key = (GdkEventKey *) event;
printf("keycode : %ld\n", key->hardware_keycode);
}return GDK_FILTER_CONTINUE; }
int main(int argc, char *argv[])
{
gtk_init(&argc, &argv);gdk_window_add_filter(NULL, &kbd_filter, NULL); gtk_main(); } --8<-------------------------------------------------------------
I compile it with "gcc -o rmp3 rmp3.c `pkg-config gtk+-2.0 --cflags` `pkg-config gtk+-2.0 --libs` (on a Mandrake 9.1) and run it with ./rmp3.
Please help ! I am searching for 2 days, I searched the mailing list archive, the net with Google, looked into source code using this function but nothing gave me an answer.
Thank you in advance.
Alexandre Jousset.
