[Plplot-cvs] plplot/examples/c++ wxPLplotDemo.cpp, NONE, 1.1 CMakeLists.txt, 1.13, 1.14

[Werner S. <sm...@us...>]

Update of /cvsroot/plplot/plplot/examples/c++
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv5384/examples/c++

Modified Files:
	CMakeLists.txt 
Added Files:
	wxPLplotDemo.cpp 
Log Message:
Added the wxPLplotDemo.cpp which shows how to use the wxwidgets bindings (based on minimal.cpp wxwidgets sample). The example will also be copied to the install tree, but the Makefile has yet to be changed - need this to do in Linux since the Makefile doesn't work in Windows.
