Widget.sendFocusChange

Sends the focus change event to widget

This function is not meant to be used by applications. The only time it should be used is when it is necessary for a #GtkWidget to assign focus to a widget that is semantically owned by the first widget even though it’s not a direct child - for instance, a search entry in a floating window similar to the quick search in #GtkTreeView.

An example of its usage is:

GdkEvent *fevent = gdk_event_new (GDK_FOCUS_CHANGE);

fevent->focus_change.type = GDK_FOCUS_CHANGE;
fevent->focus_change.in = TRUE;
fevent->focus_change.window = _gtk_widget_get_window (widget);
if (fevent->focus_change.window != NULL)
  g_object_ref (fevent->focus_change.window);

gtk_widget_send_focus_change (widget, fevent);

gdk_event_free (event);
