Qt C++属性类型提供给 QML调用

#include <QGuiApplication> #include <QQmlApplicationEngine> #include <QQmlContext> #include "student.h" int main(int argc, char *argv[]) { QGuiApplication app(argc, argv); QQmlApplicationEngine engine; Student student; engine.rootContext()->setContextProperty("student", &student); engine.load(QUrl(QStringLiteral("qrc:/main.qml"))); if (engine.rootObjects().isEmpty()) return -1; return app.exec(); }
