if you don't need the thread, and you might not
you're gonna wait until is done or cancel it any way :)
the very basics would be like this
1. import time
2.
3. def anyFunction():
4. progBar = nuke.ProgressTask("Progress job") // create the progress
5.
6. for i in xrange(0, 100):
7. if progBar.isCancelled(): // handle cancel button
8. break;
9. print "doing some stuff" // what is being processed
10. progBar.setProgress(i) // set the progress percentage
11. time.sleep(0.2) // only there so you can see the
progress not needed
// in actual code
12.
13. anyFunction()
so the range can be the number of files to copy, number of read nodes etc
cheers!!
