You should ask why I forget to add GDK_SCROLL_MASK
gtk_widget_set_events (GTK_WIDGET (layout),
GDK_EXPOSURE_MASK
| GDK_LEAVE_NOTIFY_MASK
| GDK_BUTTON_PRESS_MASK
| GDK_BUTTON_RELEASE_MASK
| GDK_POINTER_MOTION_MASK
| GDK_POINTER_MOTION_HINT_MASK
| GDK_SCROLL_MASK
);
then you have to
g_signal_connect(G_OBJECT(layout), "scroll-event\0",
G_CALLBACK(layout_callback), NULL);
gboolean
layout_callback(GtkWidget *widget, GdkEvent *event, gpointer user_data)
{
/* do your thing */
return(FALSE);
}
