I hope I can explain this correctly.

I have a GUI, which is already being processed by a mainloop. I want to be able to open a second window so the user can interact with specific information in the second window. I pulled together this code example

from Tkinter import *

class Net:
def __init__(self,tkWin):
self.window = tkWin
def show(self,t):
self.l = Label(self.window,text=t)
self.l.grid()
button = Button(self.window, text="Again")
button.bind("<Button-1>", self.Again)
button.grid()
def Again(self,event):
win3 = Tk()
x = Net(win3)
x.show("window 3")

root = Tk()
root.title = "test"
f = Frame(root,bg="Yellow")
l = Label(f,text="window 1")
f.grid()
l.grid()

win2 = Tk()
x = Net(win2)
x.show("window 2")
if __name__ == "__main__":
root.mainloop()

Is this the right way to do things, or would you suggest something different?

Thanks,
Chris

Using Tkinter.Toplevel may be better. :)

I thought that would be a good idea, so I changed the code a bit to this:

from Tkinter import *

class Net:
def __init__(self):
self.window = Toplevel()
def show(self,t):
self.l = Label(self.window,text=t)
self.l.grid()
button = Button(self.window, text="Again")
button.bind("<Button-1>", self.Again)
button2 = Button(self.window, text="Dismiss")
button2.bind("<Button-1>", self.window.destroy)
button.grid()
button2.grid()
def Again(self,event):
x = Net()
x.show("window 3")

root = Tk()
root.title = "test"
f = Frame(root,bg="Yellow")
l = Label(f,text="window 1")
f.grid()
l.grid()

x = Net()
x.show("window 2")
if __name__ == "__main__":
root.mainloop()

I put the call to Topevel into the Class. This however, gets me an error message

Traceback (most recent call last):
File "a.py", line 27, in <module>
x = Net()
File "a.py", line 5, in __init__
self.window = Toplevel()
File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/lib-tk/Tkinter.py", line 1978, in __init__
self.title(root.title())
TypeError: 'str' object is not callable

I should think it would work, but I don't understand why it doesn't.

Thanks

Try

root.title("test")

title() is a method that you are hiding with your attribute leading to
problems later on.

By the way, what kind of documentation are you using for your efforts?

Here's a concise one:

http://infohost.nmt.edu/tcc/help/lang/python/tkinter.html

Also, effbot.org has a lot of information that you best access via Google.

I have several python books and I have been using effbot and various other sources. Thanks for the help. Your suggestion (and a couple others I added) got my example working exactly like I want it, so I can incorporate that into my program. Thanks again.

Chris
