What is the value returned by a Dialog?

[xXZeroXx]

Hello, this is my first post here, and I'm having some trouble with Python.
I'm actually using wxPython the issue is, I've created a Dialog with wx.MessageDialog(....), and it displays and everything, i just don't know how to interact with it, I mean:

-Dialog
|Yes|No|

If I click yes, it closes, if I click No it closes, how do I make those buttons actually do something?.
I think what I'm looking for is some kind of return value so in that case I would be able to do:
if dialog.returnValue == Ok:
do this

I've searched trough Google but I didn't find anything and wxpython wiki seems to be down.
So.. any ideas?

Without knowing wxPython I can't be sure, but I don't see why you can't just have this:

mdialog = wx.MessageDialog(None, "What's new with you?", wx.YES_NO | wx.ICON_QUESTION)
retvalue = mdialog.ShowModal()

I would think that the ShowModal function itself would return the value from the Dialog, since execution effectively stops there and waits for a user response. However, I have no way to know what ShowModal would return.

Next time download the docs!

Thanks for your answer, anyway, wxPython wiki is back online and I was able to solve the problem it was something like:

if Dialog.ShowModal() == wx.ID_YES:
            print "You pressed Yes"
        else:
            print "You pressed No"

So thanks anyway
BTW is there really some method to download documentation? because I've searched but didn't find anything.
