Otto Wyss This patch corrects several bugs in the wxSlider class for the wxUniversal/MSW port. It affects the files "slider.h", "slider.cpp", "win32.cpp" and "gtk.cpp" (and others). The slider should now work as expected. A simple test program can be downloaded from "http://dpartialmirror.sourceforge.net/Test/". git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@18897 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
