mainwindow.cpp @ 99

Last change on this file since 99 was 99, checked in by laleppa, 14 years ago

Fixed a bug when a solution couldn't be found for some tasks while the task had at least one solution (mostly, tasks with a lot of restrictions).
Fixed a bug when Save As dialog always appeared (even for non-Untitled files) when selecting Save in Unsaved Changes dialog.
Improved the solution algorithm.
Moved progress dialog from CTSPSolver to MainWindow?. CTSPSolver doesn't contain any GUI related code now.

+ Added routePartFound() signal to CTSPSolver which is emitted once every time a part of the route is found.
+ Added cancel() slot and wasCanceled() public function to CTSPSolver to be able to cancel a solution process and to know whether it was canceled.
+ Progress is now shown when generating a solution output.
+ Check for updates functionality (only in Windows version at this moment).
