Bind to any method

You don't need of course, it's just for demo information.

Boa is well done for editing, simple objects generation, also for 
learning, but not for complex operation. It's not a good idea to use it 
for your present need.

In the help file, there is an alphabetic classes list, with (quite) all 
the methods.

See before. This is the best, and also the demo (and also the sources).

The best is probably boa, because it have got a debugger, with a 
separate process launched for testing.

All what you have to do is :
     def __init__(self, parent):
         self._init_ctrls(parent)
         self.t1 = wx.Timer(self)
         self.t1.Start(2000) # 2 seconds
         self.Bind(wx.EVT_TIMER, self.OnTest1Timer)

     def OnTest1Timer(self, evt):
         if os.path.isfile('App1.py'):
             i = wx.Image('image.jpg',wx.BITMAP_TYPE_JPEG)
             b1 = wx.BitmapFromImage(i)
             self.staticBitmap1.SetBitmap(b1)
And you can continue to use Boa as usual.
Hope you'll enjoy,

Ps: tested on xp, pretty sure it works also on linux.
