You have misunderstood how signals work. Unless you are using a queued connection \
emitting a signal simply invokes a list of callbacks (ie. the slots).

If your GUI is freezing then your slots are taking too long to run without giving the \
event loop a chance. Call QCoreApplication.processEvents() in your slot.
