source: tspsg-svn/trunk/src/settingsdialog.cpp @ 91

Last change on this file since 91 was 87, checked in by laleppa, 15 years ago

+ Added Fractional accuracy (in decimail places) to settings.
+ Created defaults.h file. Moved all default defines there.

  • Replaced all double types with qreal.
  • Replaced all calls to trUtf8() with tr() as we use setCodecForTr() to set UTF-8 encoding as default and tr() is enough.
  • Replaced all 2009 with 2010 in copyrights.
  • Fixed an error when loading .zkt file with less than 5 cities.
  • Property svn:keywords set to Id URL
