I tried several ways to use grey-out buttons but there is a bug or something that is preventing me. The only way I found is multi-threading or simply leaving the main thread to wait for the backend to finish its job until it becomes available to the user. Multi-threading can allow the user to click the same button several times in a very short time creating as several concurrent threads attempting to do the same thing. I tried to prevent this by counting the number of thread objects created but there is a bug that is preventing the created object to decrement the variable when their destructor is called. So, I am sort of, stuck. :(
The only way that does not allow multiple similar threads is to allow the GUI to become momentarily unresponsive.
