Method

GtkWidgetdispose_template

since: 4.8

Declaration [src]

void
gtk_widget_dispose_template (
  GtkWidget* widget,
  GType widget_type
)

Description [src]

Clears the template children for the widget.

This function is the opposite of gtk_widget_init_template(), and it is used to clear all the template children from a widget instance. If you bound a template child to a field in the instance structure, or in the instance private data structure, the field will be set to NULL after this function returns.

You should call this function inside the GObjectClass.dispose() implementation of any widget that called gtk_widget_init_template(). Typically, you will want to call this function last, right before chaining up to the parent type’s dispose implementation, e.g.

static void
some_widget_dispose (GObject *gobject)
{
  SomeWidget *self = SOME_WIDGET (gobject);

  // Clear the template data for SomeWidget
  gtk_widget_dispose_template (GTK_WIDGET (self), SOME_TYPE_WIDGET);

  G_OBJECT_CLASS (some_widget_parent_class)->dispose (gobject);
}

Available since: 4.8

Parameters

widget_type

Type: GType

The type of the widget to finalize the template for.
