Below is a snippet from /usr/include/gtk-3.0/gtk/gtkwidget.h lines 968 to 981 .
GDK_AVAILABLE_IN_ALL
void gtk_widget_set_events (GtkWidget *widget,
gint events);
GDK_AVAILABLE_IN_ALL
void gtk_widget_add_events (GtkWidget *widget,
gint events);
GDK_AVAILABLE_IN_ALL
void gtk_widget_set_device_events (GtkWidget *widget,
GdkDevice *device,
GdkEventMask events);
GDK_AVAILABLE_IN_ALL
void gtk_widget_add_device_events (GtkWidget *widget,
GdkDevice *device,
GdkEventMask events);
As you can see, the functions gtk_widget_set_events and
gtk_widget_add_events use gint while the functions
gtk_widget_set_device_events and gtk_widget_add_device_events use
GdkEventMask.
As gir2pas does not have any information about the underlying type of
events, it can not use Pascal set type for events in the two upper
functions, but can do that for the two others.
This can only be solved by requesting a change on GTK sources.
