Re: gtk_widget_set_events and gtk_widget_add_events

Hi,

gtk_widget_add_events() lets previously activated events on, whereas
gtk_widget_set_events() erase them. For example, when you write :

  gtk_widget_set_events(widget, GDK_KEY_PRESS_MASK);
  gtk_widget_set_events(widget, GDK_KEY_RELEASE_MASK);

... only GDK_KEY_RELEASE_MASK is activated, whereas :

  gtk_widget_add_events(widget, GDK_KEY_PRESS_MASK);
  gtk_widget_add_events(widget, GDK_KEY_RELEASE_MASK);

... both are activated.

Regards,
  Fabien Bouleau
