From c1ed9babc732a56e978f21eeeb0be9da16197b5b Mon Sep 17 00:00:00 2001 From: Tomaz Canabrava Date: Wed, 5 Feb 2014 14:25:28 -0200 Subject: Move the divetooltipitem to its own file. This is needed so we can share the dive tooltip item with the new and old profile at the same time. Next few commits will be setting the functionality of the tooltip item on the new one.
