From 166ac140f8e01369a5d281c2918b0f8b9045f8e5 Mon Sep 17 00:00:00 2001 From: drw Date: Sun, 13 Apr 2003 22:32:47 +0000 Subject: Revamped NetSystemTime! Changes include: 1. improved UI (e.g. ok/cancel work, timezone correctly changes date, new layout better suited for running in landscape mode, etc.) 2. improved code organization 3. smaller executable --- (limited to 'noncore/settings/netsystemtime/timetabwidget.cpp') diff --git a/noncore/settings/netsystemtime/timetabwidget.cpp b/noncore/settings/netsystemtime/timetabwidget.cpp new file mode 100644 index 0000000..6f24462 --- a/dev/null +++ b/noncore/settings/netsystemtime/timetabwidget.cpp @@ -0,0 +1,292 @@ +/* +                This file is part of the OPIE Project + =. +             .=l.
