Hi Ralf,
I don't know the answer on your question, however...
If you're looking for some way of running long task in a background (for
not blocking main loop) then you might want to consider using Qt Concurrent.
Here's what I'm doing for my long tasks through Qt Concurrent:
// Initializes watching for async operation results
// Watcher might be a member of the current class (in UI it should be Model
class)
QFutureWatcher watcher = new QFutureWatcher();
watcher.finished.connect(this, "onFinished()");
// Forces method execution of rmethod run() in the background
future = QtConcurrent.run(this, this.getClass().getMethod("run"));
if (future != null) watcher.setFuture(future);
// According to watcher initialization, this method will be called when
execution will be done
// Results of execution might be retrieved by calling watcher.result()
private void onFinished() {
}
Qt Concurrent has some known advantages compared to raw threads.
Sorry if I'm off topic.
