I have a very simple app with just a window. I'm testing some code which grabs input from a remote and inserts events as keystrokes. Here's some sample code:


keyVal = getRemoteData();
GdkEvent *event = gdk_event_new(GDK_KEY_PRESS);
GdkEventKey *tmpKey = (GdkEventKey*)event;
tmpKey->window = gdk_get_default_root_window();
tmpKey->send_event = 1;
tmpKey->time = CUR_TIME;
tmpKey->keyval = keyVal;
tmpKey->state = 0;
tmpKey->length = 0;
tmpKey->string = "";
tmpKey->hardware_keycode = 0;
tmpKey->group = 0;
fprintf(stderr, "Put keypress\n");


I've added code to gdk_event_peek and my event gets placed on the queue. However, it never gets removed. I have code which peeks at the queue everytime and the first entry is always the entry I get back.

Any idea why my queue isn't emptying? I have attached a "key-press-event" signal to the window, added GDK_KEY_PRESS_MASK events to the window, and grabbed focus.

Any help would be greatly appreciated.

Hello and welcome to the Gtk+ forums.

What value are you returning from your "key-press-event" callback? I think you need to return TRUE to remove current event from the cue (but I'm not sure, since I've never done anything similar to what you're doing).
