Adds a child. The @type parameter can be used to differentiate the kind of child. #GtkContainer implements this to add add a child widget to the container, #GtkNotebook uses the @type to distinguish between page labels (of type "page-label") and normal children.
Constructs a child of a buildable that has been specified as “constructor” in the UI definition. #GtkUIManager implements this to reference to a widget created in a <ui> tag which is outside of the normal GtkBuilder UI definition hierarchy. A reference to the constructed object is returned and becomes owned by the caller.
Called for each custom tag handled by the buildable when the builder finishes parsing (see @custom_tag_start)
Called for the end tag of each custom element that is handled by the buildable (see @custom_tag_start).
Implement this if the buildable needs to parse content below <child>. To handle an element, the implementation must fill in the @parser and @user_data and return true. #GtkWidget implements this to parse keyboard accelerators specified in <accelerator> elements. #GtkContainer implements it to map properties defined via <packing> elements to child properties. Note that @user_data must be freed in @custom_tag_end or @custom_finished.
the parent class
Returns an internal child of a buildable. #GtkDialog implements this to give access to its @vbox, making it possible to add children to the vbox in a UI definition. Implement this if the buildable has internal children that may need to be accessed from a UI definition.
The getter corresponding to @set_name. Implement this if you implement @set_name.
Called when a builder finishes the parsing of a UI definition. It is normally not necessary to implement this, unless you need to perform special cleanup actions. #GtkWindow sets the #GtkWidget:visible property here.
Sets a property of a buildable object. It is normally not necessary to implement this, gobject.object.ObjectWrap.setProperty is used by default. #GtkWindow implements this to delay showing itself (i.e. setting the #GtkWidget:visible property) until the whole interface is created.
Stores the name attribute given in the GtkBuilder UI definition. #GtkWidget stores the name as object data. Implement this method if your object has some notion of “name” and it makes sense to map the XML name attribute to it.
The #GtkBuildableIface interface contains method that are necessary to allow #GtkBuilder to construct an object from a #GtkBuilder UI definition.
