void destroy ( GtkWidget* widget )
Destroys a widget.
When a widget is destroyed all references it holds on other objects will be released:
- if the widget is inside a container, it will be removed from its parent
- if the widget is a container, all its children will be destroyed, recursively
- if the widget is a top level, it will be removed from the list of top level widgets that GTK+ maintains internally
It’s expected that all references held on the widget will also
be released; you should connect to the
if you hold a reference to
widget and you wish to remove it when
this function is called. It is not necessary to do so if you are
GtkContainer, as you’ll be able to use the
GtkContainerClass.remove() virtual function for that.
It’s important to notice that
gtk_widget_destroy() will only cause
widget to be finalized if no additional references, acquired
using g_object_ref(), are held on it. In case additional references
are in place, the
widget will be in an “inert” state after calling
widget will still point to valid memory, allowing you
to release the references you hold, but you may not query the widget’s
You should typically call this function on top level widgets, and rarely on child widgets.
