为了使该类型对 QML 可见,我们在 Q_PROPERTY 行之后添加 QML_ELEMENT 宏。这告诉 Qt 该类型应该对 QML 可用。如果要提供与 C++ 类不同的名称,可以使用 QML_NAMED_ELEMENT 宏。 待办事项 待办事项 最后不要忘记调用 make install 。否则,您的插件文件将不会被复制到 qml 文件夹,并且 qml 引擎将无法找到该模块。
1)在Qmake中添加声明: CONFIG += qmltypes QML_IMPORT_NAME = YourModuleNameInQML QML_IMPORT_MAJOR_VERSION = 1 2)在自定义的C++类中声明(每个要在QML中调用的类都要声明): class QMLElementA: public QObject { Q_OBJECT QML_NAMED_ELEMENT(QMLElementA) } class QMLElementB: public QObject { Q_O...
NOTE: When classes have the same name but are located in different namespaces using QML_ELEMENT on both of them will cause a conflict. Make sure to use QML_NAMED_ELEMENT() for one of them instead. 如果有多个相同名称的类(处于不同命名空间),则使用QML_NAMED_ELEMENT() 宏来区分不同命名空间的...

You should explicitly register the enclosing types of any enums you want to use in QML, using QML_ELEMENT or QML_NAMED_ELEMENT, rather than rely on their enums to be injected into other types. class OtherType : public QObject { Q_OBJECT QML_ELEMENT public: enum SomeEnum { A, B, C...
在最初的实现中,我们获得了6.0的QmlElement元素装饰器,它取代了C++中的QML_ELEMENT,这是自然的,我们将继续暴露越来越多的装饰器来改进项目的QML支持。 Starting from 6.3 you can also use QmlAnonymous, QmlAttached, QmlExtended, QmlForeign, QmlNamedElement and QmlUncreatable. New examples under examples/dec...
