Add ability to block call button until call has finished

See original GitHub issue

It’s currently possible to press the call button several times in a row, which will launch multiple runs one after the other - see my toy example below. For computationally intensive tasks it would be nice to be able to ‘block’ any more pressing of the call button if the main function is currently being run.

from magicgui import magicgui
import time

@magicgui(call_button="Run")
def run_timer():
    print('Asleep')
    time.sleep(2)
    print('Awake')

run_timer.show()

since this issue has already been solved for synchronous code, and an async solution is out of scope for the near-term (and there is a workaround), I’m going to close this. but feel free to open if new issues arise

Sorry no, I meant you can use the same call button (we should make it public), but set it to disabled, and then connect to the threadworker finished signal to trigger a callback that re-enables the button.

Let me try to create an example later today.
