mainwindow.cpp @ 80

Last change on this file since 80 was 80, checked in by laleppa, 15 years ago

+ Added Wait Cursor on city number change, because it can take some time (e.g. when changing from 5 to 50 cities).

Moved platform specific action definitions from .ui to source.
Changed random generation to include defined maximum (it was up to maximum previously).
Reverted from native to Qt open/save file dialog under WinCE, because it is more convenient than the native one.
English translation is now always loaded at application start before any other language is loaded. This is done to support plurals and some special characters that Qt translation system doesn't "like".
Updated translations to reflect recent changes.
