RE: [gtk-list] GtkEntry specific accelerators

[Eden Li <tile primenet com>]

You attach a call back func to the "key_press_event" on the entry widget you
want to make this happen to.  i.e.

#include <gdk/gdkkeysyms.h>

...
        entry = gtk_entry_new ();
        gtk_signal_connect (GTK_OBJECT (entry), "key_press_event",
                GTK_SIGNAL_FUNC (plus_handler), NULL);
...

gint
plus_handler (GtkWidget *w, GtkEventKey *ev, gpointer p)
{
        guint keyval = ev->keyval;

        /* look in /usr/include/gdk/gdkkeysyms.h for other
         * key values */
        if (keyval == GDK_plus)
        {
                ...

                /* stop the event, we've already handled it */
                gtk_signal_emit_stop_by_name (GTK_OBJECT (w),
                        "key_press_event");
                return 1;
        }

        /* let gtk handle it */
        return 0;
}

According to Sean Christopher Rhea:

| If I want to catch a specific key only when the focus is in a specific
