QStandardItemEditorCreator 類提供注冊 Widget 的可能性,不必子類化 QItemEditorCreatorBase . 更多...
| 頭: | #include <QStandardItemEditorCreator> |
| qmake: | QT += widgets |
| Since: | Qt 4.2 |
| 繼承: | QItemEditorCreatorBase |
該類在 Qt 4.2 引入。
| QStandardItemEditorCreator () |
| virtual QWidget * | createWidget (QWidget * parent ) const override |
| virtual QByteArray | valuePropertyName () const override |
This convenience template class makes it possible to register widgets without having to subclass QItemEditorCreatorBase .
範例:
QItemEditorFactory *editorFactory = new QItemEditorFactory; QItemEditorCreatorBase *creator = new QStandardItemEditorCreator<MyFancyDateTimeEdit>(); editorFactory->registerEditor(QVariant::DateType, creator);
設置
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 QStyledItemDelegate s to set and retrieve the data (using Qt's 元對象係統 ). You set the user property with the USER keyword:
Q_PROPERTY(QColor color READ color WRITE setColor USER true)
