<URL: http://bugs.freeciv.org/Ticket/Display.html?id=14639 > This transaction appears to have no content Here's the finished theme handling patch. Themes for the SDL client are expected in "themes/gui-sdl" within any of the freeciv data directories and they are recognized by the "theme.themespec" file (example: "/~/.freeciv/themes/gui-sdl/deluxe/theme.themespec"). The repackaged "deluxe" theme can be found here: http://web.inf.tu-dresden.de/~s3564543/freeciv-sdl/deluxe_theme.tar.bz2 <http://web.inf.tu-dresden.de/%7Es3564543/freeciv-sdl/deluxe_theme.tar.bz2> Using some of aneglus' graphics seems a good idea. The diplomacy icons, if we have to replace them, should maybe look more like the ones currently used. Here's a screenshot showing the diplomacy dialog in action: http://rcswww.urz.tu-dresden.de/~s3564543/freeciv-sdl/diplodlg.png<http://rcswww.urz.tu-dresden.de/%7Es3564543/freeciv-sdl/diplodlg.png> Red seals fit perfectly, don't they?Here's the finished theme handling patch.
