Detailed Description

This convenience template class makes it possible to register widgets without having to subclass QItemEditorCreatorBase.


 QItemEditorFactory *editorFactory = new QItemEditorFactory;
 QItemEditorCreatorBase *creator = new QStandardItemEditorCreator<MyFancyDateTimeEdit>();
 editorFactory->registerEditor(QVariant::DateType, creator);

Setting the editorFactory created above in an item delegate via QStyledItemDelegate::setItemEditorFactory() makes sure that all values of type QVariant::DateTime will be edited in MyFancyDateTimeEdit.

The editor must provide a user property that will contain the editing data. The property is used by QStyledItemDelegates to set and retrieve the data (using Qt's meta-object system). You set the user property with the USER keyword:

 Q_PROPERTY(QColor color READ color WRITE setColor USER true)
