Ensure that a dialog is fully drawn

[Torsten Bronger]

Hallöchen!

I defined a simple subclass of wx.Dialog called "WaitDialog", which
I'd like to use like this:

        wait_message = WaitDialog(_(u"I'm bootstrapping, please be patient") + u" …", _(u"Bootstrapping"))
        wait_message.Show()
# Here
        wx.Sleep(5)
        wait_message.Destroy()

However, the frame of wait_message can never be really seen (at
least not on my GTK system) because it's not updated early enough.
How can I be sure that the frame is fully drawn at the point marked
with "Here"?  Thank you!

Tschö,
Torsten.
