Where is wxActivate record defined ?

[ggaliens]

Code:

$ cd ..
$ find . -name "*.erl" -exec grep -H "wxActivate" {} \;
./src/wings_io_wx.erl:  {{value, #wx{event=#wxActivate{}}}, Eq} ->
./src/wings_io_wx.erl:  {{value, #wx{event=#wxActivate{}}}, Eq} ->
./src/wings_io_wx.erl:filter_resize(#wx{event=#wxActivate{}}=Ev0, Eq0) ->
./src/wings_io_wx.erl:  {{value, #wx{event=#wxActivate{}}=Ev}, Eq} ->
./src/wings_io_wx.erl:wx_translate_1(#wx{event=#wxActivate{active=Active}}) ->
$ find . -name "*.hrl" -exec grep -H "wxActivate" {} \;
$ pwd
/c/Users/markw/wings-2.0.1
$ find . -name "*.*" -exec grep -H "wxActivate" {} \;
grep: .: Invalid request code
