我正在使用Qt编写GUI应用程序。
主线程负责GUI并创建QThread以便与对象一起执行一些工作。
class Worker
{
void start() {
QTimer* timer = new Timer();
connect(timer,SIGNAL(timeout()),this,SLOT(do()));
}
void do() {
//do some stuff
emit finished();
}
}
class GUI
{
//do some GUI work then call startWorker();
void startWorker() {
QThread* thread = new Thread();
Worker* worker = new Worker();
worker->moveToThread(thread);
connect(thread, SIGNAL(started()), worker, SLOT(start()));
connect(worker, SIGNAL(finished()), workerthread, SLOT(quit()));
connect(worker, SIGNAL(finished()), worker, SLOT(deleteLater()));
}
}
现在我有几个问题:
The timer in my worker class does not work. Maybe it is because the new thread has no event loop, but I have no idea how to create such one. I tried
connect(workerthread, SIGNAL(started()), workerthread, SLOT(exec()));
but it does not work either.
When I try to wait on the new thread, the signal is never sent
class GUI { void exit() { thread->wait(); } }
我认为这也是因为没有事件循环,因此没有信号被发出。
有人有解决这些问题的想法吗?
