More specific? I dunno, I have trouble thinking of that
huge multitude of names in wx as specific. Who knows what
in all that might collide with names you devise?
My formative experience came when I was looking at Python
Imaging Library Demo code. Somebody did a simple call to
open and got returned an entire Jpeg image object. I knew
that open was destined to take arguments other than simple
file paths, and return things other than simple files, but
it seemed awfully soon. Then I got suspicious, looked at
the top of the code, and saw "from Image import *"
So a word, too, to people writing demo programs. Writing
"from mycode import *" obscures which code is actually yours
in the code following. Kind of defeats the purpose.
Cheers, Mel.
