g_object_ref and g_object_unref in widget implementations

[Bastiaan Veelo <bastiaan sarc nl>]

Hi,

I am writing my own widget, and while looking at the widgets in GTK I 
notice the following.

If a widget draws on its parent GdkWindow, you generally see

> widget->window = gtk_widget_get_parent_window (widget);
> g_object_ref (widget->window);

But widget->window is not g_object_unref-ed anywhere in the widget 
implementation. Why shouldn't it?


Thanks,
Bastiaan.
