The QStandardItemEditorCreator class provides the possibility to register widgets without having to subclass QItemEditorCreatorBase.
This convenience template class makes it possible to register widgets without having to subclass QItemEditorCreatorBase.
Example:
QItemEditorFactory *editorFactory = new QItemEditorFactory; QItemEditorCreatorBase *creator = new QStandardItemEditorCreator<MyFancyDateTimeEdit>(); editorFactory->registerEditor(QVariant::DateType, creator);
Setting the editorFactory
created above in an item delegate via QItemDelegate::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 QItemDelegates 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)
See also QItemEditorCreatorBase, QItemEditorCreator, QItemEditorFactory, QItemDelegate, and Color Editor Factory Example.
Constructs an editor creator object.
