I wrote a script that can draw polylines (it over on github) from ScalableVectorGraphics(.svg) by moving the Mouse accordingly.
When you are handing the control over your mouse to a script, a killswitch is certainly necessary, so I found an example for a Keyboard listener somwhere on the Internet:
def on_press(key):
try:
sys.exit()
print('alphanumeric key {0} pressed'.format(key.char))
print('adsfadfsa')
except AttributeError:
print('special key {0} pressed'.format(
key))
def main():
listener = keyboard.Listener( #TODO fix sys.exit()
on_press=on_press)
listener.start()
if __name__ == '__main__':
main()
It seems to be working: If i add a a print statement before the sys.exit() it is instantly executed properly. But with sys.exit() it keeps moving my mouse and the python interpreter is still on Taskmanager. I don't know why it keeps executing.
Thank you in advance for your suggestions. MrSmoer
Solution was: os._exit(1)
