I thought I should add that I cannot derive my render thread from QThread. As a possible solution, will creating an intermediate QObject to connect the render thread to emit signals to the UI provide the needed synchronization?
1 - Derive an object from QObject
2 - Connect derived QObject signal to the GUI's updateImage slot.
3 - Make derived QObject receive the callback from my render thread and emit the signal and synchronization will be handled automatically?
Thanks again,
