Wxwidgets (formerly known as wxwindows) is a class library for c++ providing gui components and other facilities on several popular platforms (and some unpopular ones as well).

this package provides a debug version of the wxgtk library. it is compiled both with -g for normal debugger tracing and with the __wxdebug__ flag which provides many internal checks by wxwidgets itself that are not performed on apps compiled with the 'release version' libs in the -dev package.
