11/21/2023 0 Comments Qt signals slots threads example![]() This is a very simple example that demonstrates two types of workers. You have two classes and the thread subclass really isn’t necessary when using You could getĪround this limitation by putting the functionality in a separate class but now It also ties theįunctionality to a thread making code reuse low in this case. Idea but I don’t think it’s the cleanest approach. The other documented approach is subclassing QThread. ![]() That said, I don’t like how Qt’s documentation explains this. I like using a QObject worker and I think this is the best (and easiest)Īpproach. Subclass QThread and reimplement the run function. ![]() The two other approaches are defined by Qt’s QThreadĭocumentation. Use a non-Qt solution when Qt already provides portable threading. You can use an already built portable thread library but why I don’t like this approach because you’re basically writing a portable ![]() The first is using system threads, either pthread or Windows There are three main ways I’ve seen people handle basic threading in their QtĪpplications. Still basic / direct / low level threading (I’ll just call thisīasic) is often seen as difficult with Qt. Threads can be difficult and Qt provides a lot of ways to make threads easy to Over the years using Qt I’ve seen a lot of difficulty using threads with Qt.
