Im trying to code a simple GUI but I'm having a bit of a problem. Heres my
code: from tkinter import *class Application(Frame):
def __init__(self,master=None):
Frame.__init__(self,master)
self.grid(sticky=N+S+E+W)
self.createWidgets() def createWidgets(self):
top=self.winfo_toplevel()
top.rowconfigure(0,weight=1)
top.columnconfigure(0,weight=1)
self.rowconfigure(0,weight=1)
self.columnconfigure(0,weight=1)
self.Nothing =
Button(self,text='Nothing',activebackground='red',cursor='gumby',command=self.configure())
self.Nothing.grid(row=0,column=0,sticky=N+S+E+W) def
configure(self):
self.Nothing.configure(text='Hello!')app = Application()
app.master.title("The Nothing Button")
app.mainloop() when I run the batch file, i get this error:Traceback (most
recent call last):
File "C:\Python32\gui2.py", line 21, in <module>
app = Application()
File "C:\Python32\gui2.py", line 7, in __init__
self.createWidgets()
File "C:\Python32\gui2.py", line 15, in createWidgets
self.Nothing =
Button(self,text='Nothing',activebackground='red',cursor='gumby',command=self.configure())
File "C:\Python32\gui2.py", line 19, in configure
self.Nothing.configure(text='Hello!')
AttributeError: 'Application' object has no attribute 'Nothing' What I get from
that is that its claiming that my Application class doesnt have an attribute
called 'Nothing' but I clearly defined it in the 'createWidgets()' method. Can
anyone explain to me exactly what the problem is. Thanks.
