示例1: reload
void Reloader::reload()
{
qDebug() << "reloading";
//The engines has a internal cache that prevents reloading.
QQmlEngine *engine = m_viewer->engine();
engine->trimComponentCache();
engine->clearComponentCache();
m_viewer->setSource(m_mainFile);
}示例2: clearComponentCache
void tst_qqmlengine::clearComponentCache()
{
QQmlEngine engine;
// Create original qml file
{
QFile file("temp.qml");
QVERIFY(file.open(QIODevice::WriteOnly));
file.write("import QtQuick 2.0\nQtObject {\nproperty int test: 10\n}\n");
file.close();
}
// Test "test" property
{
QQmlComponent 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 2.0\nQtObject {\nproperty int test: 11\n}\n");
file.close();
}
// Test cache hit
{
QQmlComponent 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
{
