From: Drew Fisher Date: Fri, 11 Nov 2011 23:25:18 +0000 (-0800) Subject: Reorganize directory tree, add a Qt graphical demo. X-Git-Url: http://git.zarvox.org/shortlog/2013?a=commitdiff_plain;h=d7480309d9bc12520cb73dd564beba8244ae2aca;p=libtouchmouse.git Reorganize directory tree, add a Qt graphical demo. I'll probably have to redo some more CMake stuff to make the Qt demo optional.
