mainwindow.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.
