Python: Allow keypress signals from gtk.window to stop a loop

Question

So, essentially, I want something that can do this:

def onKeyPress(widget, event):
    if event.state & gtk.gdk.CONTROL_MASK and keyname == "a":
        Stop the loop somehow.

def doLoop(widget):
    while True:
        print "You're in"
        print "a loop"


mywindow = gtk.Window()
mywindow.connect("key_press_event", onKeyPress)
foo = gtk.Foo()
foo.connect("bar", doLoop)
mywindow.add(foo)

I don't know how to accomplish this, but I have tried using threading or different .py files, but I am kind of a beginner, so I want to know if there's an easier way.

Try having a boolean called KeyPressed that can be accessed from both the doLoop and onKeyPress functions. Then you can do this:

def onKeyPress(widget, event):
    if event.state & gtk.gdk.CONTROL_MASK and keyname == "a":
        KeyPressed = False

def doLoop(widget):
    while KeyPressed:
        print "You're in"
        print "a loop"


mywindow = gtk.Window()
mywindow.connect("key_press_event", onKeyPress)
foo = gtk.Foo()
foo.connect("bar", doLoop)
mywindow.add(foo)

KeyPressed would have to be set to True from the beginning.

Can you tell why? I don't have gtk so I can't debug. Is KeyPressed being set to False? – austin-schick Mar 31 '14 at 15:37
Well, the loop is too busy, well, doing itself to allow the code to respond to mywindow. – user3299890 Mar 31 '14 at 17:18
