[Discuss-gnuradio] Q about ScopeSink2

[Michael Dickens]

I'm finishing up my changes to gr-wxgui in my branch 'wxgui',  
inserting a few changes I figured out from my demos from last week.   
One particular one I'm wondering about is the following line from (my  
new) scopesink2.py:433 :

        self.data_event = window_data_event (
            self, self.format_data, lambda e, w, h: w.Connect (-1,  
-1, e, h))

I've read about the .Connect method (from wxWidgets, not from  
wxPython) [it comes from wx.EvtHandler, which is then inherited into  
all wx.Window types], and cannot figure out why to use that instead of  
the usual .Bind  method.  The only thing I can think of is  
that .Connect is more general in what it can do ... but it's not being  
used that way here (the '-1's are defaults).  Commenting out the  
lambda and such - to use .Bind - works just fine.  Any ideas /  
memories / comments?  Thanks! - MLD
