Send Var to Main thread

[Alexanov]

Hi
How can I send Variable or data from worker Thread (or other Thread implementation ) to Gui (Main Thread)?
I do vice versa (Gui Thread to other thread ) with signal/slot.

@Alexanov
Thats exactly the way to do it:

signals:
   void sendData(QVariant value);

...
slots:
   void getData(QVariant value);


//connect the 2

connect(ObjectInThread1, &myThreadedClass1::sendData, ObjectInThread2, &mainThreadClass::getData, Qt::QueuedConnection);

the with5th paramter is optional, but either leave it open aka Qt::AutoConnection or write Qt::QueuedConnection

@Alexanov There is no difference whether from main thread to other thread or from other thread to main thread.
