Get your Thread class to emit a signal. Create a slot on your guiwindow class. 
Connect the signal to the slot using a Qt::QueuedConnection. Do the necessary 
disabling/enabling in the slot which will of course have full access to the 
needed members.

In principal this would allow you access but it would be a bad idea and a 
waste of time. It is a bad idea because you wold be exposing internal data 
breaking encapsulation. And it would be a waste of time as Qt does not allow 
you to modify the GUI form any thread other than the main thread. Please read 
the documentation on multithreading with Qt:

Good luck,
