                      QNamespaceContainer

Known Subclasses:: wdysini.IniFileContainer, localization.LocalizationContainer

Base class to assemble methods and logic in its own class.

Slot methods (on_method_event()) are automatically connected to widgets of the parent. If the methods takes an argument you *must* apply a @pyqtSignature() decorator!

connect(), disconnect(), emit() and attribute access are forwarded to the parent class (like Zope2 implicit acquisition wrapper) but you *must* use self.context instead self as argument.

>>> class MyStuff(QNamespaceContainer):
...     def initialize(self): 
...         self.connect(self.context, SIGNAL("foo()"), bar)
...
...     @pyqtSignature("int")
...     def on_button_clicked(self, boolean):

Now add the container to your class >>> class MainWindow(QtCore.QObject): ... def __init__(self, parent=None): ... QtCore.QObject.__init__(self, parent=None) ... self.qcMystuff = MyStuff(parent)

Warning: If you are creating new QObject based instances you should bind them to self.context and *not* to self. This is especially true for QWidget based objects.

init(self, parent)
(Constructor)

Constructor

Calls initialize() and auto connects slot methods with parent's widgets.

Parameters:

parent (a QObject based instance) - the Qt parent object

Overrides: sip.wrapper.__init__

connect(self, *args)

Shortcut for self.parent().connect(*args)

Overrides: PyQt4.QtCore.QObject.connect

disconnect(self, *args)

Shortcut for self.parent().disconnect(*args)

Overrides: PyQt4.QtCore.QObject.disconnect

emit(self, *args)

Shortcut for self.parent().emit(*args)

Overrides: PyQt4.QtCore.QObject.emit

getattr(self, name, default=_marker)
(Qualification operator)

Get attributes form parent.

Works similar to Zope 2's Implicit Acquisition wrapper.

initialize(self)

Initialize method

Must be implement in the subclass

context

Shortcut for self.parent()

Get Method:: unreachable.context(self) - Shortcut for self.parent()

Set Method:

None

- helper for pickle

Delete Method:

None

- helper for pickle
