This *calls* self.com(a) and assigns its *results* (which happens to be
None) to the command option in your button. So your button does nothing.
To do what you want, use:
self.a = Button(self.frame,text="button")
self.a.pack()
Checkbutton(self.frame,text="hello",variable=self.var,command=self.com).pack()
in __init__, then:
def com(self):
if self.var.get()==1:
self.a.config(state=ENABLED)
else:
self.a.config(state=DISABLED)
