Added wxDisplayChangedEvent and triggering in MSW, when display mode changes this event gets triggered. I don't know what should happen with other OS's since I am not familiar with how they handle mode changes. Watcome Version 11 now compiles with wide character support. Fixed watcom warnings in html/htmlwin.h imagbmp.h listctrl.h imagbmp.cpp quantize.cpp strconv.cpp variant.cpp dirctrlg.cpp treectlg.cpp m_style.cpp fontenum.cpp listctrl.cpp ole\dataobj.cpp textctrl.cpp window.cpp xml.cpp msw/setup.h with watcom version 11 it now compiles with wide character support. xrc/xml.cpp fixed memory leak and compile warnings git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@14057 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775

The boolean value of the variable

REMARKS:
|
|
To create new variables for the #if, #else and #endif HTML preprocessing
|
|
blocks you need to derive classes from wxIfElseVariable and override the
|
|
pure virtual GetValue function. However this should not be done directly
|
|
but by using the BEGIN_IFELSE_VARIABLE and END_IFELSE_VARIABLE macros
