builderObjects -- A list of UI object names that should be extracted from
|
|
uiFile and exposed for this class to use. If this list
|
|
is empty, all objects will be exposed.
|
|
|
|
Only the following kinds of objects need to be exported:
|
|
|
|
(1) Top-level objects (like GtkDialogs) that are directly
|
|
used in Python.
|
|
|
|
(2) Top-level objects that are not directly used in
|
|
Python, but are used by another object somewhere down
|
|
in the hierarchy. This includes things like a custom
|
|
GtkImage used by a button that is part of an exported
|
|
dialog, and a GtkListStore that is the model of a
|
|
Gtk*View that is part of an exported object.
|
|
mainWidgetName -- The name of the top-level widget this object
|
|
object implements. This will be the widget searched
|
|
for in uiFile by the window property.
|
|
focusWidgetName -- The name of the widget to focus when the object is entered,
|
|
or None.
|
|
uiFile -- The location of an XML file that describes the layout
|
|
of widgets shown by this object. UI files are
|
|
searched for relative to the same directory as this
|
|
object's module.
|
|
translationDomain-- The gettext translation domain for the given GUIObject
|
|
subclass. By default the "anaconda" translation domain
|
|
is used, but external applications, such as Initial Setup,
|
|
that use GUI elements (Hubs & Spokes) from Anaconda
|
|
can override the translation domain with their own,
|
|
so that their subclasses are properly translated.
|
|
helpFile -- The location of the yelp-compatible help file for the
|
|
given GUI object. The default value of "" indicates
|
|
that the object has not specific help file assigned
|
|
and the default help file should be used.
