Dive site: add dive site list tab Add a very simple tab-widget presenting the list of known dive sites. The table is rendered using our custom "TableView". The (mis)uses the "LocationInformationModel". It moves the items to be displayed (delete, name, description, number of dives) to the front and makes the others hidden. Moreover, it was necessary to limit the geo-tag decoration role to the name to avoid having the icon next to each column. Make the trash-can icon active and the name and description editable. This is modelled after the cylinders-table code. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at> 2019-03-09 21:32:16 +00:00			`// SPDX-License-Identifier: GPL-2.0`

Dive site: introduce proxy model DiveSiteSortedModel The LocationInformationModel used to sort its entries and was completely rebuilt after every change. This makes it rather complex to support incremental changes. Instead, keep LocationInformationModel sorted by UUID so that indexes are consistent with indices in the core dive site table. Implement sorting by other columns than name and enable sorting in the dive site view. Finally, don't cache the list of dive site names for the mobile app, since that would also need some rather convoluted methods of keeping the list up to date. Calculate it on the fly.

Undo: implement undo of dive site addition Implement a dive site addition undo command and connect it to the add dive site button. The added dive site has a default name ("new dive site"). Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at> 2019-03-13 19:58:25 +00:00			`private slots:`

Dive site: on first addition of dive site, edit name When adding a dive site, enter the name field of the new dive site. Thus, when adding a new dive site, the user can immediately edit the name. The code is rather subtle: It hooks into the dive site added signal before executing the command and unhooks afterwards. This only works, because signals are executed in order of connect - thus the model adds the index first and only then is the field edited.

Dive site: scroll to changed dive site If the name of a dive site is edited, it might wander somewhere else in the table and thus out of view. Hook into the "dive site changed" signal and scroll there. The code is rather subtle as it depends on signals being called in a certain order: First the item is moved in the model, only then can we scroll to the correct place.

Dive site: implement purge of unused dive sites Add a "purge unused dive sites" button to the dive site list. Connect it to a new PurgeUnusedDiveSites command. Implementation was trivial: simply copy the DeleteDiveSites command. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at> 2019-03-19 18:52:54 +00:00			`void on_purgeUnused_clicked();`
