browser is a widget that enables the user to edit a344# given set of properties. Each property is represented by a label345# specifying the property's name, and an editing widget (e.g. a line346# edit or a combobox) holding its value. A property can have zero or347# more subproperties.348#349# QtGroupBoxPropertyBrowser provides group boxes for all nested350# properties, i.e. subproperties are enclosed by a group box with351# the parent property's name as its title. For example:352#353# \image qtgroupboxpropertybrowser.png354#355# Use the QtAbstractPropertyBrowser API to add, insert and remove356# properties from an instance of the QtGroupBoxPropertyBrowser357# class. The properties themselves are created and managed by358# implementations of the QtAbstractPropertyManager class.359#360# \sa QtTreePropertyBrowser, QtAbstractPropertyBrowser361###362###363# Creates a property browser with the given \a parent.364###365class QtGroupBoxPropertyBrowser(QtAbstractPropertyBrowser):366 def __init__(self, parent=None):367 super(QtGroupBoxPropertyBrowser, self).__init__(parent)368 self.d_ptr = QtGroupBoxPropertyBrowserPrivate()369 self.d_ptr.q_ptr = self370 self.d_ptr.init(self)371 ###372 # Destroys this property browser.373 #374 # Note that the properties that were inserted into this browser are375 # \e not destroyed since they may still be used in other376 # browsers.
