示例1: QDBusAbstractAdaptor
NelisquareDbus::NelisquareDbus(QApplication *parent, QDeclarativeView *view) :
QDBusAbstractAdaptor(parent), m_view(view)
{
QDBusConnection bus = QDBusConnection::sessionBus();
bus.registerService("com.nelisquare");
bus.registerObject("/com/nelisquare", parent);
QObject *rootObject = qobject_cast<QObject*>(view->rootObject());
rootObject->connect(this,SIGNAL(processUINotification(QVariant)),SLOT(processUINotification(QVariant)));
rootObject->connect(this,SIGNAL(processURI(QVariant)),SLOT(processURI(QVariant)));
}示例2: test
void test()
{
QObject *o;
int a, b, c;
auto f = [&a]() {}; // OK
o->connect(o, &QObject::destroyed, [a]() {}); // OK
o->connect(o, &QObject::destroyed, [&a]() {}); // Warning
QObject::connect(o, &QObject::destroyed, [&a]() { }); // Warning
QObject::connect(o, &QObject::destroyed, [&]() { a; b; }); // Warning
QObject::connect(o, &QObject::destroyed, [=]() { a; b; }); // OK
A *a1;
QObject::connect(o, &QObject::destroyed, [a1]() { a1->v; }); // OK
QObject::connect(o, &QObject::destroyed, [&a1]() { a1->v; }); // Warning
}示例3: setHtml
void setHtml(QTextEdit * edit, const QString & html) {
QtConcurrent::run([=]{
// runs in a worker thread
auto doc = new QTextDocument;
