RE: Tkinter - changing existing Dialog?

2006-06-02 Thread Michael Yanowitz 
Thanks.

  That is what I was looking for. The configure command (as you and John
pointed out),
should do what I need. The first response of starting a new thread was not
what I was
looking for.

To disable/deactivate a button widget, use the keyword 'state'.  For
example, 


import Tkinter as Tk
root = Tk.Tk()
bid = Tk.Button(root, text='test', state=Tk.NORMAL)
bid.pack()
bid.configure(state=Tk.DISABLED)

If you want to hide the button (using Pack geometry manager):

bid.pack_forget()

You can pack it again using bid.pack() but it may be difficult to pack
it back where you originally intended.

If you are using the Grid geometry manager:

bid.grid_forget()

To put it back simply call grid again with the same row, column.



Changing the text of a label or button already drawn is simply done by a
call to the configure method on the button or label's text attribute:

bid.configure(text='Help')

John

Tkinter - changing existing Dialog?

2006-06-01 Thread Michael Yanowitz 
Hello:


   I have a Tkinter GUI Dialog with many buttons and labels and text
widgets.
What I would like to do is, can I:

1) Disable/deactivate/hide a button, text widget that is already drawn (and
   of course the opposite enable/activate/show it)?

2) Change the text of a label or button that is already drawn?

  based on actions taken by the user. Can it be done without destroying
the present dialog or the objects in it and creating a new one?

  Sorry for what probably is such a trivial and basic question. I just can't
find the answer or know what the technical term for what I want to do is to
search for it myself.

Thanks in advance:
Michael Yanowitz
