Widget.initTemplate

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.WidgetClass.setTemplate].

It is important to call this function in the instance initializer of a [gtk.widget.Widget] 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 [gobject.object.ObjectWrap.new_] on a widget with composite templates,

it’s important to build the composite widgets before the construct properties are set. Properties passed to [gobject.object.ObjectWrap.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.
