source: tspsg-svn/trunk/src/settingsdialog.cpp @ 78

Last change on this file since 78 was 78, checked in by laleppa, 15 years ago

+ Added an ability to disable showing of the solution steps' matrices in solution output.

  • Replaced Ok and Cancel buttons in SettingsDialog? with QButtonBox. Now the buttons conform the interface guidelines of the target platform.
  • Increased the allowed maximum number of cities to 50. Solution steps' matrices aren't shown by default if the number of cities in task is more than 15.
  • For WinCE the size of the toolbar buttons is now determined based on the device DPI instead of its resolution.
  • Open and save file dialogs are now using native dialogs where supported.
  • Reworked About dialog a little bit.
  • Property svn:keywords set to Id URL
