Member Function Documentation

void MExtensionArea::addWidget	(	QGraphicsWidget *	widget,
		MDataStore &	store
	)			[protected, virtual, slot]

addWidget performs setup of an extension widget and it's datastore when the widget is being added to the extension area. The ownership of the widget remains on the caller of this slot. This slot can be overridden in specialized extension areas to provide additional setup.

Parameters:

	widget	Widget to be added onto the MExtensionArea.
	store	This MDataStore object can be used to store permanent extension area data related to this particular application extension instance. When the same application extension instance is reinstantiated, this API will be called with the data that was stored to the permanent storage the last time around. This can be used to store for instance layout data of an application extension instance or any other extension area specific data.

Definition at line 117 of file mextensionarea.cpp.

{
    Q_D(MExtensionArea);

    d->addWidget(widget, store);
}

void MExtensionArea::removeWidget

(

QGraphicsWidget *

widget

)

[protected, virtual, slot]

removeWidget performs cleanup related to a widget that is being removed. The widget itself should not be deleted in this method, it will be deleted by the caller.

Parameters:

widget

The widget to be removed from the system.

Definition at line 124 of file mextensionarea.cpp.

{
    Q_D(MExtensionArea);

    d->removeWidget(widget);
}
