Method

GtkWindowset_default

[−]

Declaration [src] 

void
gtk_window_set_default (
  GtkWindow* window,
  GtkWidget* default_widget
)
[−]

Description [src]

The default widget is the widget that’s activated when the user presses Enter in a dialog (for example). This function sets or unsets the default widget for a GtkWindow. When setting (rather than unsetting) the default widget it’s generally easier to call gtk_widget_grab_default() on the widget. Before making a widget the default widget, you must call gtk_widget_set_can_default() on the widget you’d like to make the default.
