[Glade-users] Remove and create new gtk objects

[Duarte Duque]

Dear List Members,
I am trying to remove dynamically some objects from an gtk based program
and replace them with new objects. The problem occurs when I try to set
some events to the new objects that will be created.

There is what I am doing:
/***************************************************/

GtkWidget* create_window (void)
{
    GtkWidget *window1;
    GtkWidget *alarm;
    gint z;
    …
    alarm = gtk_drawing_area_new();
    gtk_widget_ref(alarm);
    gtk_object_set_data_full(GTK_OBJECT(window1), “alarm”, alarm,
(GtkDestroyNotify)gtk_widget_unref);
    gtk_widget_show(alarm);
    gtk_fixed_put(GTK_FIXED(fixed1), alarm, 20, 40);
    gtk_widget_set_uposition(alarm, 20, 40);
    gtk_widget_set_usize(alarm, 10, 10);
    z = 1;
    gtk_object_set_user_data(GTK_OBJECT(alarm),(void *)z);
    gtk_widget_set_events (alarm, GDK_BUTTON_PRESS_MASK |
GDK_ENTER_NOTIFY_MASK | GDK_LEAVE_NOTIFY_MASK);
    gtk_widget_set_extension_events (alarm, GDK_EXTENSION_EVENTS_CURSOR);
    signal_disconnect_alarm[0] = gtk_signal_connect(GTK_OBJECT (alarm),
“realize”, …
    signal_disconnect_alarm[1] = gtk_signal_connect(GTK_OBJECT (alarm),
“button_press_event”, …
    signal_disconnect_alarm[2] = gtk_signal_connect(GTK_OBJECT (alarm),
“enter_notify_event”, …
    signal_disconnect_alarm[1] = gtk_signal_connect(GTK_OBJECT (alarm),
“leave_notify_event”, …
    …
    return window1;
}
/***************************************************/

I can draw the new objects in the window, but the button_press_event, the
enter_notify_event and the leave_notify_event don’t work.

The stdout prints this errors messages when I try to create new objects:
Gtk_CRITICAL **: file gtkwidget.c: line 3824(gtk_widget_set_events):
assertion ‘GTK_WIDGET_REALIZED (widget)’ failed

Any ideas?

Best Regards,
Duarte Duque
