patch: Drag and Drop patch for pyCrust

Hi all,
I was just playing with DnD because I thought that would be nice to have in
my "favorite" python shell.
So this allows to just drag-and-drop a file into the shell- and that
appends:
r"C:\long filename.txt"

So here is my short addition to shell.py in wxWindows/wxPython/
( my version shows:
__author__ = "Patrick K. O'Brien <pobrien@orbtech.com>"
__cvsid__ = "$Id: shell.py,v 1.1.2.5 2003/05/03 16:01:40 PKO Exp $"
__revision__ = "$Revision: 1.1.2.5 $"[11:-2]
)
in
class Shell(editwindow.EditWindow):
<snip>
   def __init__(self, <snip>)
          <snip>
         # I append
         #seb: File drag and drop
         self.SetDropTarget( FileDropTarget(self) )
<snip>
#at the end of the file
#seb : File drag and drop
class FileDropTarget(wx.FileDropTarget):
    def __init__(self, obj):
        wx.FileDropTarget.__init__(self)
        self.obj = obj
    def OnDropFiles(self, x, y, filenames):
      txt = 'r\"%s\"' % filenames[0]
      n = len(txt)
      self.obj.AppendText(n, txt)
      pos = self.obj.GetCurrentPos() + n
      self.obj.SetCurrentPos( pos )
      self.obj.SetSelection( pos, pos )

That seems to be all - the way I get rid of the filename being selected
afterwards (by calling SetSelection) seems to be a hack...

Thanks for this nice shell - I actually didn't know if this is the best
place to post this.
Also I would like to make a note:
   The main disadvantage of calling pyCrust now 'py' is that it is now
impossible to 'google' for it...
   Maybe everyone can agree to refer to as pyCrust :wink:

Have fun and enjoy,
