You don't need to call "mainloop()" when building Tkinter
widgets on the command-line, but for *real* scripts i believe
you'll need to. For instance, if you run the following code
you will see a window with a label inside:
You are right
In fact, I used to open *.py programs with IDLE and then I run
programs from IDLE menu. With this way, mainloop( ) is not
needed.
I tried to double click on a *.py to run a program. Without
mainloop( ), the console appears a split seconds, then
deseapears, and that's all. With mainloop( ) it works.
> Second question, is it possible to cancel a mainloop() ?
I don't think you meant to say "cancel", did you really mean
"pause"?

Sounds like you're trying to create a modal dialog, yes?
Tkinter has a few methods for handling such cases. One is
called "wait_window" and another is called "quit", with
"wait_window" being preferred over "quit" for most tasks.
There are also methods for setting the input "focus" and
"grab". A good example for you to look at is the
tkSimpleDialog.Dialog class.
OK
tkinter.simpledialog.askstring is exactly what I need
Thanks
