I am trying to structure a Tkinter application with classes instead of
just with simple functions, but I'm not sure how to call methods from my
main class.
My main class is packetstreamApp(). Within that class I call various
methods, including drawGUI() and authorizeDump(). My problem comes when
I try to call authorizeDump from the Tkinter menu. Here is the code that
calls authorizeDump():
self.packetmenu.add_command(label="Start Network Monitor",
command=packetstreamApp.authorizeDump())
Here is the code for authorizeDump():
def authorizeDump(self):
##do stuff here
And here is the error message that comes when I try to call authorizeDump():
Traceback (most recent call last):
File "/Users/kevin/Programming/packetstream/packetstream-classes.py",
line 257, in <module>
app = packetstreamApp()
File "/Users/kevin/Programming/packetstream/packetstream-classes.py",
line 19, in __init__
self.drawGUI()
File "/Users/kevin/Programming/packetstream/packetstream-classes.py",
line 49, in drawGUI
self.packetmenu.add_command(label="Start Network Monitor",
command=packetstreamApp.authorizeDump())
TypeError: unbound method authorizeDump() must be called with
packetstreamApp instance as first argument (got nothing instead)
I don't know how to interpret this error message, and so can't implement
a fix. Can anyone shed light on what I'm doing wrong?
Thanks.
