'NoneType' object has no attribute 'bind'

[Alex]

hi there, I keep getting the message in the Topic field above.

Here's my code:

self.click2=Button(root,text="Click Me").grid(column=4,row=10)
self.click2.bind("<Button-1>",self.pop2pop)

def pop2pop(self,event):

print("Adsfadsf")
newpop=IntVar()
newpop=self.PopSize.get();


what am I doing wrong?

cheers,

Alex

hi there, I keep getting the message in the Topic field above.

Here's my code:

self.click2=Button(root,text="Click Me").grid(column=4,row=10)

Replace the above line to

button = Button(root, text="Click Me")
print "Button() returns", button
grid = button.grid(column=4, row=10)
print ".grid() returns", grid
self.click2 = button

and be enlighted. Then remove the print statements.

self.click2.bind("<Button-1>",self.pop2pop)

def pop2pop(self,event):

print("Adsfadsf")
newpop=IntVar()
newpop=self.PopSize.get();

If one step doesn't work try to replace it with smaller steps and add print
statements to find the part that doesn't do what you expected.

Here's my code:

self.click2=Button(root,text="Click Me").grid(column=4,row=10)
self.click2.bind("<Button-1>",self.pop2pop)

From reading the Tkinter docs grid doesn't itself return a control. So
I think you want this:

self.click2 = Button(root, text="Click Me")
self.click2.grid(column=4, row=10)
self.click2.bind("<Button-1>", self.pop2pop)

However, that's totally untested so don't take it as gospel.
