'modal dialogs' with Tkinter

[Sean McIlroy]

I'd like to have a function f such that, when f is invoked, a Tk
window w is presented in which a number of variables can be modified,
and f returns the values that are indicated by the relevant
menus/checkbuttons/etc at the time w gets closed. I've tried various
ways of doing this, without success. Any assistance would be greatly
appreciated.

Peace,

Here are the necessary ritual incantations to create a modal dialog with Tkinter:

dlg = Toplevel()
# ... build the window ...
## Set the focus on dialog window (needed on Windows)
dlg.focus_set()
## Make sure events only go to our dialog
dlg.grab_set()
## Make sure dialog stays on top of its parent window (if needed)
dlg.transient(parentWdw)
## Display the window and wait for it to close
dlg.wait_window(dlg)

The callbacks for your "OK", "Cancel" or whatever buttons you want to use should then call dlg.destroy(). This will terminate the wait_window call and continue the execution of the code after it.

does the approach described here work for you?

(note that the tkSimpleDialog module is included in Python's standard library)

if it doesn't work, what doesn't work as required/expected?

You could try using: EasyGUI http://www.ferg.org/easygui/

EasyGUI is different from other GUIs in that EasyGUI is NOT
event-driven. It allows you to program in a traditional linear fashion,
and to put up dialogs for simple input and output when you need to. If
you have not yet learned the event-driven paradigm for GUI programming,
EasyGUI will allow you to be productive with very basic tasks
immediately. Later, if you wish to make the transition to an
event-driven GUI paradigm, you can do so with a more powerful GUI
package such as anygui, PythonCard, Tkinter, wxPython, etc.

It works for me and is easy to modify to your needs.
