widget (Fl_File_Input is much lighter-weight, and is simpler in function.) Update file chooser dialog to use new Fl_File_Input widget and always display absolute path. Still need to do docos, new screenshots, and update FLUID to support the new widget. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.1@2145 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
