Last change on this file since 104 was 104, checked in by laleppa, 15 years ago
  • Improved the solution output generation algorithm. Now it works directly with QTextDocument instead of "feeding" it with HTML. Thanks to this the solution output generation is now about 1.65 times faster.
  • Added .txt extension to ChangeLog?, INSTALL and README files to simplify opening these files in Windows.
  • Made a small improvement to Settings Dialog to follow the current application palette.
  • Output text color if not set is now determmined based on the current application palette.
  • Property svn:keywords set to Id URL
