详细描述

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 .

范例：

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

设置 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 QItemDelegate s to set and retrieve the data (using Qt's 元对象系统 ). You set the user property with the USER keyword:

Q_PROPERTY(QColor color READ color WRITE setColor USER true)
