[R-gui] R-wxPython no longer needs parser.so!

[James Wettenhall]

Hi,

After a bit of discussion about how to build Python from source 
so that parser.so etc. depend on libpython2.2.so, I now have
a simpler next-step-forward for people interested in playing 
with R-wxPython - I've removed all dependency to the Python 
parser module in wxPython 2.2 at:
http://bioinf.wehi.edu.au/folders/james/wxPython/

(One other change - I've replaced the "print" generic functions 
with "show".  "show" is more S4-style.)

There are certainly still some problems, maybe partly due to the 
fact that I'm trying to make an object-oriented GUI toolkit look 
imperative from the R command-line user's perspective.   But 
aside from the problems, there's also some interesting progress!

With R-wxPython 2.2, now I can run the "Choose GUI toolkit" 
example from the documentation, including a listbox with 
scrollbars, and two buttons.  It doesn't actually appear 
straight away, but when I issue another wxPython command 
afterwards, like wxMessageBox("Hello"), then it appears (one 
command too late), but the buttons don't work.  Same with the 
"Text Editor" example - if I follow it with a call to 
wxMessageBox() then it appears after the wxMessageBox() call, 
but at least it appears, so that's something! 

It's a bit hard to destroy these late-appearing windows/widgets 
- wxClose, wxDestroy don't seem to work yet on R-wxPython with 
Gtk/Linux, probably because of this 'delay' problem.  But for 
me, running X11 from Windows via XWin32, there's always 
"End Task" from the Windows Task Manager to kill a window, 
(and similar for other OS's)! :)

Regards,
James
