 154 # $Log$
 155 # Revision 1.2  1998/12/15 20:44:34  RD
 156 # Changed the import semantics from "from wxPython import *" to "from
 157 # wxPython.wx import *"  This is for people who are worried about
 158 # namespace pollution, they can use "from wxPython import wx" and then
 159 # prefix all the wxPython identifiers with "wx."
 160 #
 161 # Added wxTaskbarIcon for wxMSW.
 162 #
 163 # Made the events work for wxGrid.
 164 #
 165 # Added wxConfig.
 166 #
 167 # Added wxMiniFrame for wxGTK, (untested.)
 168 #
 169 # Changed many of the args and return values that were pointers to gdi
 170 # objects to references to reflect changes in the wxWindows API.
 171 #
 172 # Other assorted fixes and additions.
