button resize

[Michal Tomcanyi <michal tomcanyi matfyz cz>]

Hello all,

I have a button with packed image in it and want to resize image when
the button is resized. The problem is I don't know which signal/event to
catch. 

I tried a simple example, where button is packed directly in a toplevel
window and being resized together with the window. When I attached
"configure-event" callback, it was never called. ( The event mask was
set to GDK_ALL_EVENTS_MASK for window as well as for the button).

Signals "size-allocate" and "size-request" are called together with
"clicked" signal, which I don't want.

Is there any clean solution for this? Thank you for any ideas
Michal

------- The code ----------

include <gtk/gtk.h>

gboolean button_catch(GtkButton *button, GdkEventConfigure *e, 
                        gpointer data) {

   if (data)
       g_print("Caught: %s\n",(gchar *)data);
       else g_print("Caught\n");

   return(FALSE); /* call default handlers      */
}


int main(int argc, char *argv[]) {
        GtkWidget *window, *button;

        gtk_init(&argc, &argv);
        window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
        gtk_widget_add_events(window,GDK_ALL_EVENTS_MASK);
        g_signal_connect(G_OBJECT(window), "destroy",
                G_CALLBACK(gtk_main_quit), NULL);
        gtk_window_set_default_size(GTK_WINDOW(window), 300, 300);
        button = gtk_button_new();
        gtk_widget_add_events(button,GDK_ALL_EVENTS_MASK);
        g_signal_connect(G_OBJECT(button),"configure-event",
                 G_CALLBACK(button_catch),"configure-event");
        gtk_container_add(GTK_CONTAINER(window),button);
        gtk_widget_show_all(window);
        gtk_main();
        return 0;
}
