详细描述

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)

参见 QItemEditorCreatorBase, QItemEditorCreator, QItemEditorFactory, QItemDelegate, and Color Editor Factory Example.
