From eee34232dbbd24b7b3db9e44672e240db2db50e9 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Tue, 20 Sep 2011 09:53:45 -0700 Subject: Add "Apply"/"Cancel" buttons to dive equipment page It's too damn easy to make mistakes and not even notice them (odd gtk widget selection and keyboard input), or just start editing a cylinder thing and realize it was wrong. So instead of always saving the equipment information implicitly, add explicit "Apply" and "Cancel" buttons that save the information (or re-load it from the dive data structure) So now you need to press an extra button for your changes to *really* take effect. It can be a bit annoying, but it's better than the silent accidental equipment change that could happen before.
