This is the downside of having to track our own selection state. We now have a class of dives that potentially isn't known to Gtk as we aren't adding them to the TreeView. So we need to make sure that their selection state is consistent by deselecting them (either when they are marked as invalid OR when we change preferences to no longer show invalid dives). And because Gtk sends out another set of selection events when clearing the TreeView (not sure why), we also need to make sure that their selection state isn't reset to selected by mistake when the divelist is recreated. A bit of a pain, but it seems to work now and be consistent. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
