[Discuss] Python question using tkinter LabelFrame widget

[Jerry Feldman]

I have a couple of tcl/tk scripts I want to convert to Python for a 
couple of reasons:
1. Python is a better programming language than tcl.
2. Noone else in my group knows tcl/tk
3. One of the products that the tcl/tk application interfaces with uses 
Python for its installerand I can clean up the interface.
The only issue I have at the moment is using the LabelFrame widget. In 
one of the applications, I am using a tcl/tk labelframe and it works 
fine, but not in Python. I don't have to use the LabelFrame but it 
separates these radio buttonsfrom text boxes later on in the 
application. I've tried things like adding columnconfigure(), but that 
had no effect.
#!/usr/bin/python

import Tkinter


# define
class lfex_tk(Tkinter.Tk):
     def __init__(self,parent):
         Tkinter.Tk.__init__(self,parent)
         self.parent = parent
         self.initialize()

     def initialize(self):
         self.grid()

         self.command = Tkinter.StringVar()
         self.entry = Tkinter.Entry(self,width=60,textvariable=self.command)
         self.entry.grid(column=0,row=0,sticky='EW')
         self.command.set(u"Enter data")


### define buttons
         run = Tkinter.Button(self,text=u"data",
command=self.OnRunButtonClick)
         self.labelVariable = Tkinter.StringVar()
         kwit = Tkinter.Button(self,text=u"Quit",
command=self.OnQuitButtonClick)

### Set up the grids for row 0
         run.grid(column=1,row=0)
         kwit.grid(column=6,row=0, sticky='E')

         self.resizable(True, True)
         self.update()
         self.geometry(self.geometry())
         self.entry.focus_set()
         self.entry.selection_range(0, Tkinter.END)

         radios = Tkinter.LabelFrame(self,borderwidth=10,text="Commands")
         radios.grid(column=0,row=3, padx=5, pady=5)
         whichCMD = Tkinter.StringVar()
         radios.one = Tkinter.Radiobutton(radios, text="One", 
variable=whichCMD, value="One")
         radios.two = Tkinter.Radiobutton(radios, text="Two", 
variable=whichCMD, value="Two")
         radios.three= Tkinter.Radiobutton(radios, text="Three", 
variable=whichCMD, value="Three")
         ## Default to radio button 1
         radios.one.select()
         self.update()


## Button Actions
     def OnQuitButtonClick(self):
         app.destroy()

     def OnRunButtonClick(self):
         # does nothing for this example
         self.entry.focus_set()
         self.entry.selection_range(0, Tkinter.END)


if __name__ == "__main__":
     app = lfex_tk(None)
     app.title('LabelFrameTest')
     app.mainloop()
