示例1: clearComponentCache

void tst_qdeclarativeengine::clearComponentCache()
{
    QDeclarativeEngine engine;

    // Create original qml file
    {
        QFile file("temp.qml");
        QVERIFY(file.open(QIODevice::WriteOnly));
        file.write("import QtQuick 1.0\nQtObject {\nproperty int test: 10\n}\n");
        file.close();
    }

    // Test "test" property
    {
        QDeclarativeComponent component(&engine, "temp.qml");
        QObject *obj = component.create();
        QVERIFY(obj != 0);
        QCOMPARE(obj->property("test").toInt(), 10);
        delete obj;
    }

    // Modify qml file
    {
        QFile file("temp.qml");
        QVERIFY(file.open(QIODevice::WriteOnly));
        file.write("import QtQuick 1.0\nQtObject {\nproperty int test: 11\n}\n");
        file.close();
    }

    // Test cache hit
    {
        QDeclarativeComponent component(&engine, "temp.qml");
        QObject *obj = component.create();
        QVERIFY(obj != 0);
        QCOMPARE(obj->property("test").toInt(), 10);
        delete obj;
    }

    // Clear cache
    engine.clearComponentCache();

    // Test cache refresh
    {
        QDeclarativeComponent component(&engine, "temp.qml");
        QObject *obj = component.create();
        QVERIFY(obj != 0);
        QCOMPARE(obj->property("test").toInt(), 11);
        delete obj;
    }

示例2: reloadQML

void QmlBeam::reloadQML(QUrl mainFile)
{
    // The mainFile parameter is ignored, instead a property is used to cover non-default asset names.
    Q_UNUSED(mainFile);

    // Get the context of the first scene root to keep the contextProperties.
    QDeclarativeContext* context = QDeclarativeEngine::contextForObject(mRoot);

    // Clear the QML cache.
    QDeclarativeEngine* appEngine = context->engine();
    appEngine->clearComponentCache();

    // Reload all QML.
    QmlDocument* qml = QmlDocument::create(mMainFile);
    AbstractPane *root = qml->createRootObject < AbstractPane > (context);
//    qml->setParent(root);
    Application::instance()->setScene(root);
