I am writing a large Python/Tkinter/Pmw program. It has become so big that I
would like to move some of the widget handlers to a module for import. The
following small program illustrates:
# --- begin code ---
# checkbutton frame using python & Tkinter
from Tkinter import *
import string
class CheckButton_1(Frame):
def __init__(self,msg):
Frame.__init__(self,master)
self.grid(
)
self.createWidgets()
def createWidgets(self):
self.var = IntVar()
c = Checkbutton(
master,
text='Check if yes',
variable=self.var,
command=self.handlerCheckButton,
)
c.grid(
)
def handlerCheckButton(self):
self.doNotSend=self.var.get()
if self.doNotSend:
print "\nChecked"
else:
print "\nNot checked"
if __name__ == "__main__":
master=Tk()
master.title("Checkbutton test")
msg='If checked, do NOT send me a copy of this email'
check=CheckButton_1(msg)
check.mainloop()
# --- end code ---
If the method 'handlerCheckButton(self)' is moved to a module, them imported,
the button may come up but once the Checkbutton is checked, the code crashes
with an error.
Is there no way to put handlers in a module and import them? Is 'self' getting
in the way?
