gtk.glade.XML Signal Prototypes

gobject.GObject Signal Prototypes

Description

This object represents an `instantiation' of an XML interface description. When one of these objects is created, the XML file is read, and the interface is created. The gtk.glade.XML object then provides an interface for accessing the widgets in the interface by the names assigned to them inside the XML description.

The gtk.glade.XML object can also be used to connect handlers to the named signals in the description. Libglade also provides an interface by which it can look up the signal handler names in the program's symbol table and automatically connect as many handlers up as it can that way.

Constructor

    gtk.glade.XML(fname, root=None, domain="", typedict={})

fname :

the XML file name

root :

the widget node in fname to start building from (or None)

domain :

the translation domain for the XML file (or "" for default)

typedict :

A dictionary used to lookup types (or {} for default)

Returns :

a new gtk.glade.XML object

Creates a new gtk.glade.XML object (and the corresponding widgets) from the XML file specified by fname. Optionally it will only build the interface from the widget node specified by root (if it is not None). This feature is useful if you only want to build say a toolbar or menu from the XML file, but not the window it is embedded in. Note also that the XML parse tree is cached to speed up creating another gtk.glade.XML object for the same file.

Methods

gtk.glade.XML.signal_connect

    def signal_connect(handler_name, func)

handler_name :

the signal handler name

func :

the signal handler function

In the glade interface descriptions, signal handlers are specified for widgets by name. The signal_connect() method allows you to connect a callback specified by func to all signals in the gtk.glade.XML file with the signal handler name specified by handler_name.

gtk.glade.XML.signal_autoconnect

    def signal_autoconnect(dict)

dict :

a mapping or an instance

The signal_autoconnect() method is a variation of the gtk.glade.XML.signal_connect method. It uses Python's introspective features to look at the keys (if dict is a mapping) or attributes (if dict is an instance) and tries to match them with the signal handler names given in the interface description. The callbacks referenced by each matched key or attribute are connected to their matching signals. The argument is called dict due to compatibility reasons since originally only the mapping interface was supported. The instance variant was introduced in PyGTK 2.0.

gtk.glade.XML.get_widget

    def get_widget(name)

name :

the name of the widget

Returns :

the widget matching the name or None

The get_widget() method returns a reference to the gtk.Widget specified by name in the interface description. None is returned, if name doesn't specify a widget in the interface.

gtk.glade.XML.get_widget_prefix

    def get_widget_prefix(name)

name :

the prefix the widget names or "" for all widgets

Returns :

A list of widgets that match name as the start of their name or None

The get_widget_prefix() method returns a list of interface gtk.Widget objects that have names prefixed by name. None is returned if no interface widget names match the prefix name.

gtk.glade.XML.relative_file

    def relative_file(filename)

filename :

a relative file pathname

Returns :

the absolute file pathname

The relative_file() method resolves the relative pathname specified by filename, using the directory of the XML file as a base. If filename contains an absolute pathname, then the original file name is returned.

Functions

gtk.glade.xml_new_from_buffer

    def gtk.image_new_from_buffer(buffer, size, root="", domain="", typedict={})

buffer :

the string containing the XML buffer

size :

size of the string

root :

the widget node in fname to start building from (or "")

domain :

the translation domain for the XML file (or "" for default)

typedict :

A dictionary used to lookup types (or {} for default)

Returns :

a new gtk.glade.XML object.

The gtk.glade.xml_new_from_buffer() function creates a new gtk.glade.XML object (and the corresponding widgets) from the string specified by buffer. Optionally it will only build the interface from the widget node specified by root (if it is not ""). This feature is useful if you only want to build say a toolbar or menu from the XML document, but not the window it is embedded in.

gtk.glade.get_widget_name

    def gtk.glade.get_widget_name(widget)

widget :

a gtk.Widget

Returns :

the name of the widget

The gtk.glade.get_widget_name() function returns the name of the gtk.Widget specified by widget that was generated by a gtk.glade.XML object.

gtk.glade.get_widget_tree

    def gtk.glade.get_widget_tree(widget)

widget :

a gtk.Widget

Returns :

the gtk.glade.XML object that built widget

This gtk.glade.get_widget_tree() function is used to get the gtk.glade.XML object that built the gtk.Widget specified by widget.

gtk.glade.set_custom_handler

    def gtk.glade.set_custom_handler(handler, user_data)

handler :

the custom widget handler.

user_data :

user data passed to the custom handler.

This gtk.glade.set_custom_handler() function allows you to override the default behaviour when a Custom widget is found in an interface.

gtk.glade.bindtextdomain

    def gtk.glade.bindtextdomain(domainname, dirname)

domainname :

the name of the application.

dirname :

the directory where to find locales.

Returns :

the value of dirname

This gtk.glade.bindtextdomain() function allows you to use internationalisation with glade.

gtk.glade.textdomain

    def gtk.glade.textdomain(domainname)

domainname :

the name of the application.

Returns :

the value of domainname

This gtk.glade.textdomain() function allows you to use internationalisation with glade.

gtk.glade.set_custom_widget_callbacks

    def gtk.glade.set_custom_widget_callbacks(dict)

dict :

a dictionary of function names.

This gtk.glade.set_custom_widget_callbacks() function takes a dictionary of function names->functions, for an example see PyGTK FAQ 22.7 for an example.
