Description

A gtk.IconFactory manages a group of gtk.IconSets that manage a set of variants (for different sizes and states) of a specific icon. Icons in an icon factory are named by a stock ID, which is a simple string identifying the icon e.g "gtk-ok". Each gtk.Style has a list of gtk.IconFactorys derived from the current theme; those icon factories are consulted first when searching for an icon. If the theme doesn't set a particular icon, the search continues for the icon in a list of default icon factories, maintained by the add_default()() and remove_default()() methods. Applications with icons should add a default icon factory with their icons, which will allow themes to override the icons for the application.

To display an icon, always use gtk.Style.lookup_icon_set() on the widget that will display the icon, or the convenience function gtk.Widget.render_icon(). These functions take the theme into account when looking up the icon to use for a given stock ID.

Constructor

    gtk.IconFactory()

Returns :

a new gtk.IconFactory object

Creates a new gtk.IconFactory.

Methods

gtk.IconFactory.add

    def add(stock_id, icon_set)

`stock_id` :	an icon name
`icon_set` :	an icon set

The add() method adds the specified icon_set to the icon factory, under the name stock_id. the stock_id string should include the name of your application, e.g. "myapp-whatever-icon". Normally applications create a gtk.IconFactory, then add it to the list of default factories with the add_default(). Then they pass the stock_id to widgets such as gtk.Image to display the icon. Themes can provide an icon with the same name (such as "myapp-whatever-icon") to override your application's default icons. If an icon already existed in the icon factory for stock_id, it is unreferenced and replaced with the new icon_set.

gtk.IconFactory.lookup

    def lookup(stock_id)

`stock_id` :	an icon name
Returns :	the icon set named `stock_id`.

The lookup() method looks up stock_id in the icon factory, returning an icon set if found, otherwise None. For display to the user, you should use gtk.Style.lookup_icon_set() on the gtk.Style for the widget that will display the icon, instead of using this function directly, so that themes are taken into account.

gtk.IconFactory.add_default

    def add_default()

The add_default() method adds the icon factory to the list of icon factories searched by gtk.Style.lookup_icon_set(). This means that, for example, gtk.Image.set_from_stock() will be able to find icons in the icon factory. There will normally be an icon factory added for each library or application that comes with icons. The default icon factories can be overridden by themes.

gtk.IconFactory.remove_default

    def remove_default()

The remove_default() method removes an icon factory from the list of default icon factories. Not normally used though you might use it for a library that can be unloaded or shut down.

Functions

gtk.icon_factory_lookup_default

    def gtk.icon_factory_lookup_default(stock_id)

`stock_id` :	the stock ID to lookup
Returns :	the icon set matching `stock_id` or `None` if no icon set matches

The gtk.icon_factory_lookup_default() function returns the gtk.IconSet that has the name specified by stock_id. If the icon set cannot be found the function returns None.
