# Revision 1.2 1998/12/15 20:44:34 RD
# Changed the import semantics from "from wxPython import *" to "from
# wxPython.wx import *" This is for people who are worried about
# namespace pollution, they can use "from wxPython import wx" and then
# prefix all the wxPython identifiers with "wx."
#
# Added wxTaskbarIcon for wxMSW.
#
# Made the events work for wxGrid.
#
# Added wxConfig.
#
# Added wxMiniFrame for wxGTK, (untested.)

# Changed many of the args and return values that were pointers to gdi
# objects to references to reflect changes in the wxWindows API.
#
# Other assorted fixes and additions.
