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.
Sends the focus change @event to @widget

An example of its usage is:

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); ]|
