Detailed Description

The QItemEditorFactory class provides widgets for editing item data in views and delegates.

\inmodule QtWidgets

When editing data in an item view, editors are created and displayed by a delegate. QStyledItemDelegate, which is the delegate by default installed on Qt's item views, uses a QItemEditorFactory to create editors for it. A default unique instance provided by QItemEditorFactory is used by all item delegates. If you set a new default factory with setDefaultFactory(), the new factory will be used by existing and new delegates.

A factory keeps a collection of QItemEditorCreatorBase instances, which are specialized editors that produce editors for one particular QVariant data type (All Qt models store their data in \l{QVariant}s).

registerEditor()

void QItemEditorFactory::registerEditor	(	int	userType,
		QItemEditorCreatorBase *	creator )

Registers an item editor creator specified by creator for the given userType of data.

{Note:} The factory takes ownership of the item editor creator and will destroy it if a new creator for the same type is registered later.
