This is fine for methods that set things on the GUI, but methods that return a value could be an issue.

#Qt update gui from worker thread serial#

GUI API but has also support for networking, audio, serial port, thread.

invokeMethod is async when it's used across threads. Hughes, one of the Qt core developers, recommend that use worker objects by. As I was poking around I also found some other useful features like auto-connect and foreach. It's good ole QMetaObject::invokeMethod It does exactly what I need, invoke a method in the other thread. So that way I wouldn't have to duplicate all the work. Executing workers destructor in the same thread We made LogService to be the QThread object because we needed to implement the custom run() function. Changed() which will update the count label on the dialog box. The start() will call the threads run() method where a value. The second class would have all the signals, as well as the connect's in its constructor. In this tutorial, we will learn communication between threads and GUI control. Otherwise I'd be duplicating signal code. In my program, theres a dialog that visualizes the progress of some work. Well, no I don't need a second class, but the second class is necessary if multiple classes (working in multiple threads) need access to the GUI. Hi everybody Im having a problem with GUI and QThread.
