How do I get the trackbar value?
by Trevor Dickson in Programming Languages

I feel a little silly asking this, seems pretty simple but I can't find the solution anywhere.

In the code below I've created a loop which keeps running till 'q' is pressed. I'm using trackbars to set 2 variables. However I want to create some sort of pause to set these trackbars before running through this loop.
