[wxpython-users] The best way to handle enable/disable mutually-exclusive groups of widgets

[Raffaello Barella]

Never used pyPubSub, so far.
My solution is to have a method in care of enabling or disabling  all
controls involved.
Inside the method a tuple contains the IDs of the controls, and a list of
their default enabling values in the same order. e.g.
def ResetControls(self):
controls =3D  button1, checkbox 1, combo1, button2, radiobutton1
enables =3D [False, False, True, True, False]
# Then the different situation are exposed:
if (condition):
     enables[2] =3D enables[4] =3D False
elif (condition):
    enables[0] =3D enables[5] =3D True
#and so on

#At the end of the method a simple "for" loop:
for j in range(len(enables)):
     controls[j].Enable(enables[j])
