Method

Gtk.Widget.init_template

Declaration [src]

void
gtk_widget_init_template (
  GtkWidget* widget
)

Description [src]

Creates and initializes child widgets defined in templates.

This function must be called in the instance initializer for any class which assigned itself a template using gtk_widget_class_set_template().

It is important to call this function in the instance initializer of a GtkWidget subclass and not in GObject.constructed()or `GObject.`constructor() for two reasons:

  • derived widgets will assume that the composite widgets defined by its parent classes have been created in their relative instance initializers
  • when calling g_object_new() on a widget with composite templates, it’s important to build the composite widgets before the construct properties are set. Properties passed to g_object_new() should take precedence over properties set in the private template XML

A good rule of thumb is to call this function as the first thing in an instance initialization function.
