[Qt-interest] How to do it... in a QThread?

[Jason H]

If A B C and D are GUI objects (QLabel) you can't. 
If they are one of Qt's implicitly shared classes, then no problem.
If A B C and D are data for use in GUI objects (QLabel), then use the implicitly shared classes as return types (QString).


Also look into using QRunnable.

Subject: [Qt-interest] How to do it... in a QThread?


Dear,

I'm struggling on a problem. 

Let's suppose we have a Qt GUI Application with just a simple QButton.

When the application is started the main constructor perform some operations and set A,B,C and D variables values;

When I press the QButton I want to start a parallel process (Thread) to do some operations using A, B, C and D. I will use a QMutex to keep everything safe.

How can I make A, B, C and D visible to Thread? What I mean is: How can I manipulate the content of A, B, C and D, perform something and update the values?

Best regards,
Luiz.
