Trackbar - do not call function until LMB released

Hello,

My app with the trackbar lags everytime I make a change to the value as there is a lot of processing being done. Is there anyway I can have the program not run the function until the left mouse button is released ? The setMouseCallback function only gets invoked when the mouse click is in the display window itself so I was not able to try that out.

A link or guide to any C++ / OpenCV method would be nice..

Thanks

I found out about the GetKeyState function in C++ so I am going to investigate that
