Hi Ilknur,
self.newkey is the name of the method that creates the Toplevel window, if you
name the window self.newkey, too,
you override the method. Now when in your self.Button_Press() method the call
to self.newkey() occurs,
you actually try to "call" the newly created Toplevel window which leads to the
error message you saw.
however, still I could not reach my aim. As you will see below, I could not
assign self.userkey which is gotten from the user on toplevel window, to the
userdefinedkey[] array. the aim is, at first click of a key should result with
a toplevel window that gets the key parameter from the user. the other press of
the same key should result by calling a different function with the parameter
taken. there are more than one such a key on my GUI. I hope, I can explain my
aim and problems:) thanks from now...
The problem here seems similar, if I understand you correctly. Each call to
self.newkey() overrides a bunch of
variable names.
I think a better approach would be to write a separate class for your dialog
window; if I understand the use
of your dialog window correctly, it is probably the best (and easiest) to use
an askstring() dialog from the
tkSimpleDialog module, e.g.:
(...)
# do not forget to make the list a class attribute first
self.userdefinedkeys = ['', '']
# define the buttons like this:
self.key1 = Button(self.mycontainer, text="Key1", command=lambda index=0 :
self.button_press(index))
(...)
def button_press(self, index):
if self.userdefinedkeys[index]:
# alternative callback here
print self.userdefinedkeys[index]
else:
self.userdefinedkeys[index] = tkSimpleDialog.askstring("Enter new
key", "Key name:")
I hope this helps
Michael
