initTemplate

open fun 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 method@Gtk.WidgetClass.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.
