/**
|
|
* GtkBuildableIface:
|
|
* @g_iface: the parent class
|
|
* @set_name: 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.
|
|
* @get_name: The getter corresponding to @set_name. Implement this
|
|
* if you implement @set_name.
|
|
* @add_child: 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.
|
|
* @set_buildable_property: Sets a property of a buildable object.
|
|
* It is normally not necessary to implement this, g_object_set_property()
|
|
* is used by default. #GtkWindow implements this to delay showing itself
|
|
* (i.e. setting the #GtkWidget:visible property) until the whole interface
|
|
* is created.
|
|
* @construct_child: 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.
|
|
* @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 structure 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.
|
|
* @custom_tag_end: Called for the end tag of each custom element that is
|
|
* handled by the buildable (see @custom_tag_start).
|
|
* @custom_finished: Called for each custom tag handled by the buildable
|
|
* when the builder finishes parsing (see @custom_tag_start)
|
|
* @parser_finished: 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.
|
|
* @get_internal_child: 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 GtkBuildableIface interface contains method that are
|
|
* necessary to allow #GtkBuilder to construct an object from
|
|
* a GtkBuilder UI definition.
