QItemEditorCreator Class
template <typename T> class QItemEditorCreator通过 QItemEditorCreator 类，无需子类化QItemEditorCreatorBase 即可创建项目编辑器创建器库。更多

详细说明
QItemEditorCreator 是一个方便的模板类。它使用模板类为QItemEditorFactory 创建编辑器。这样，就无需子类化QItemEditorCreatorBase 。
QItemEditorCreator<MyEditor> *itemCreator = new QItemEditorCreator<MyEditor>("myProperty"); QItemEditorFactory *factory = new QItemEditorFactory;
构造函数接收包含编辑数据的属性名称。然后，当QStyledItemDelegate 设置和检索编辑数据时，可以通过名称访问该属性。只有当编辑器未定义用户属性（使用Q_PROPERTY 宏中的 USER 关键字）时，才可使用该类。如果 widget 有用户属性，则应使用QStandardItemEditorCreator 代替。
另请参阅 QItemEditorCreatorBase,QStandardItemEditorCreator, 和QItemEditorFactory 。
成员函数文档
[explicit] QItemEditorCreator::QItemEditorCreator(const QByteArray &valuePropertyName)
使用valuePropertyName 作为用于编辑的属性名称，构造编辑器创建者对象。QStyledItemDelegate 在设置和获取编辑器数据时会使用该属性名。
请注意，只有在编辑器部件未定义用户属性时，才会使用valuePropertyName 。
[override virtual] QWidget *QItemEditorCreator::createWidget(QWidget *parent) const
重实现：QItemEditorCreatorBase::createWidget(QWidget *parent) const.
[override virtual] QByteArray QItemEditorCreator::valuePropertyName() const
重实现：QItemEditorCreatorBase::valuePropertyName() const.
