a few stupid questions ...

hello,

I'm trying to write a cross platform simulator for PPyGui,
based on wxPython.

So the basic idea is to replace the PPyGui library with a wxPython library,
but I stumbeld over a few constructs for which I can't find a translation:

···

--------------
the first one, (literary from a demo script):
  app = gui.Application ( MainFrame () )

It isn't accepted because:
- I can't create a main frame before I've created the application

So as a work around, I changed this in
  app = gui.Application(MainFrame)

and let the gui.Application create the MainFrame
-----------------
the second one:
    gui.Message.ok ( "About", "Ppygui demo", "info", self)

I tried this
class Message ( object ) :
  def __init__ ( self ) :
    pass
  def ok ( self, caption = '', message = '', parent = None ) :
    wx.MessageDialog ( parent, message, caption,
                        style = wx.OK | wx.ICON_INFORMATION )

But that gives the following error:
unbound method ok() must be called with Message instance as first argument (got str instance instead)
---------------

thanks,
Stef Mientki

Did you instantiate a Message instance?

Maybe you want a static method, or just a plain old function in a module.

Aha, that seems to problem, the code below works now, Thanks Chris !!
