2020-05-27cleanup: un-singletonize ShiftTimesDialogGravatar Berthold Stoeger
There is no reason that this dialog is a singleton. Since it is modal, it can be created on demand. Apart from removing superfluous global state, this simplifies code, because preparing the widget can now be done in the constructor instead of overriding the showEvent() function.

2020-05-27cleanup: un-singletonize RenumberDialogGravatar Berthold Stoeger
There is no reason that this dialog is a singleton. Since it is modal, it can be created on demand. This simplifies code, because the mode (selected-only or all-dives) can be set in the constructor. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-05-06undo: make adding of pictures undoableGravatar Berthold Stoeger
This one is a bit hairy, because two things might happen if the picture has a geo location: - A dive gets a newly generated dive site set. - The dive site of a dive is edited. Therefore the undo command has to store keep track of that. Oh my. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-05-06media: move addition of pictures out of create_picture()Gravatar Berthold Stoeger
If we want to make addition of pictures undoable, then create_picture() must not add directly to the dive. Instead, return the dive to which the picture should be added and let the caller perform the addition. This means that the picture-test has to be adapted.

2020-05-03selection: create global single_selected_trip() functionGravatar Berthold Stoeger
The DiveListView had a singleSelectedTrip function that returns the selected trip if exactly one trip is selected. This could be very slow if numerous non-trip items were selected, because all the selection indices were back- translated by the proxy model. This could make selection changes very slow, because the MainTab used said function to determine whether it should show trip or dive data.. Indeed, with a 3500 dive test log, when selecting all dives in tree mode, the updating of the TabWidgets is sped up from 130 ms to 5 ms this commit.

2020-05-03selection: introduce clear_selection() functionGravatar Berthold Stoeger
The DiveListView would touch the selection-innards directly. Let's encapsulate that. Moreover, take care to reset the trip selection when resetting the core data. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-04-26selection: replace selectedTrips() by singleSelectedTrip() functionGravatar Berthold Stoeger
To check wether the tab widgets should show the trip view, they called the selectedTrips() function. The trip view was shown if that contained only one trip. However, the selectedTrips() function was very slow, because it has to query to core models. Change the function to singleSelectedTrip(), which returns a trip if there is exactly one trip selected. The function returns early if there is more than one trip selected. This makes the select-all case much faster. There are two cases which are still very slow: - List mode, because here all top-level items are queried. - Dive log with many only top-level items. Ultimately, we will have to cache the trip selection because querying the model is too slow. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-04-26desktop: select dives at onceGravatar Berthold Stoeger
The old code would call QItemSelectionModel::select() once for every dive. Instead collect the selection in a QItemSelection and only call QItemSelectionModel::select() once. This makes selecting multiple dives significantly faster. The loop also expanded the trips with selections. This has now to be done in an extra loop.

2020-04-26dive list: don't access selected dives via indicesGravatar Berthold Stoeger
When determining the selected dive sites to highlight them on the map, the DiveListView code used the local indices of the selected dives. However, that was unreasonably slow. Even though a layering violation, let's access the core data structures directly. In my tests this improved from 700 ms to 0 ms! Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-04-26selection: move test for programmatical selection changes to widgetGravatar Berthold Stoeger
The DiveListView widget has to differentiate between programmatical und user-initiated selection changes. It did so by using the DiveListNotifier::inCommand() flag. However, 1) There is only one point of entry for such selection changes, viz. the MultiFilterSortModel::selectionChanged() signal 2) This signal is not only emitted in command-context. Another source is for example dive-map selection changes. Therefore, move the programmatical-selection-change status down to the widget and set/reset it in the diveSelectionChanged() slot. This makes "select all visible dive sites" somewhat faster. Sadly, not as much as expected. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-04-25cleanup: remove DiveListView::selectDives()Gravatar Berthold Stoeger
This was used by the map to select dives. However, the map now calls the core function directly, so this can be removed. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-04-25desktop: remove selectionChangeDone() from DiveListView::selectDive()Gravatar Berthold Stoeger
This was erroneous, as it should only be called at the end of a selection change, not after every single dive. It made selection of multiple dives extremely slow.

2020-04-25desktop: remove selection-code to select a new current_diveGravatar Berthold Stoeger

2020-04-25desktop: don't select current dive after collapsing tripsGravatar Berthold Stoeger
This appears to be an artifact. Collapsing does not unselect the current dive, so reselecting it appears pointless. Also it is unclear why the selection should be restricted to a single dive after collapsing. Probably that was originally meant to expand only the trip with the current dive in it?

2020-03-01selection: update selection on key-pressesGravatar Berthold Stoeger
Commit 2cea115ddb7528d9e6dd1bf918ebf5c670b82479 "fixed" the selection by hooking into mouseRelease events. An unintended consequence was that scrolling with the cursor keys didn't update the current dive. Therefore, also hook into the corresponding key-press events. This is just horrible, but I'm not aware of any possibility to fix it properly. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-02-08Dive list: be more careful on when updating the UI after selectionGravatar Berthold Stoeger
Fix two issues: 1) When narrowing the selection, we didn't get setSelection() calls. Only, when the user released the mouse button was the selection updated. Therefore, hook into the mouse-release- event and update the UI if the selection changed. 2) We updated the ui in setSelection(). However, this was called on mouse-move even if the actual selection didn't change. Therefore, compare selection before and after processing of the event and only refresh the UI if there are changes. Clearly, this can only be a quick stopgap solution and we should find out how to properly hook into the selection change machinery. Though see commit 4928c4ae0421193bbd371cb0924091a970489611 for the reason why we do things as we do them.

2020-02-04Dive sites: select each dive site only onceGravatar Berthold Stoeger
After selecting dives, the selected dive sites are collected. This was done using the selectionModel()->selection().indexes(), which is wrong, because it gives one index per row *and* column. Accordingly, every dive site was added numerous times to the array of dive sites to be selected. Change this to selectionModel()->selectedRows(), which gives one entry per row. Moreover, if multiple dives with the same site were selected, this site was also added to the array multiple times. Therefore, check the array before adding sites. Note that all this should not change the user experience in any way, it is only a code-hygiene thing. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>

2019-12-10Dive list: access header via filter-modelGravatar Berthold Stoeger
The dive list accesses the filter model, therefore it makes sense to also get the header data from there, even if they are only forwarded from the source model. This makes control flow more logical and will allow us to remove the global DiveTripModel instance. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>

2019-12-04Cleanup: remove DiveListView::expandedRows member variableGravatar Berthold Stoeger
The QList served as backing store for backupExpandedRows() and restoreExpandedRows(). However, these always came in pairs in the same scope. There is no reason to store the expanded rows over a longer time. Therefore, return the expanded rows from backupExpandedRows() and take them as argument in restoreExpandedRows(). Morover replace the QList<int> by the much lighter std::vector<int>. We certainly don't need copy-on-write, reference-counting and immutability of iterators in this case.

2019-12-04Selection: don't reset selection when resortingGravatar Berthold Stoeger
The old code saved, cleared and restored the selection. This is not necessary anymore, because on model reset the selection, which is stored in the core, is reset. Remove the unnecessary selection handling. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-12-04Selection: move translation of indexes to filter modelGravatar Berthold Stoeger
The DiveListView caught signals from the DiveTripModel with the corresponding indexes. However, the DiveListView is actually connected to the MultiFilterSortModel and thus has to translate the indexes. Instead, catch the signals in the MultiFilterSortModel, transform them and resend. Let the DiveListView get its signal from the MultiFilterSortModel. Yes, this makes things less efficient because there is an extra signal. On the upside, the makes data-flow much more logical. Selection will have to be fixed anyway. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-12-04Selection: move initialization of selection from view to modelGravatar Berthold Stoeger
The goal here is to unify desktop and mobile by moving selection code from the desktop-only view. Currently, initialization of the selection still has to be called from the view after connecting the appropriate signals. This is due to the weird way in which create completely new models when resetting them. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-12-04Selection: move selection of "first" dive to coreGravatar Berthold Stoeger
The DiveListView has a function to select the first dive. Move this to the core to be able to call it from all parts (not only desktop) of the code. Currently, this has a (small?) UI regression: when filtering dives and no selected dive is visible anymore, the old code would select the first dive in the list. The new code selects the newest dive, which might not be the first if some sort-criterion is active. To revert to the old behavior, it will be necessary to move the sorting function likewise to the core. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>

2019-11-28Desktop: Improve speed of selecting multiple (or all) divesGravatar Berthold Stoeger
When selecting all dives via CTRL-A or manually and the trips were not expanded, the QSelectionModel sends a single selectionChanged signal per trip. We are reloading the map in every call, making this very slow. I couldn't figure out how to make QSelectionModel behave more nicely, therefore I chose the nuclear option: Remove the map reloading from selectionChanged() and hook into all functions that do selection changes. In these functions, first call the original code and then do the selection-changed operations. This will certainly need some tuning.

2019-11-19Filter: move recalculation of filter from FilterModel to TripModelGravatar Berthold Stoeger
The way this was accessed via Qt's model semantics was horrible. This gives arguably more readable code, since we don't have to shoehorn things through QVariants. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-11-19Filter: split out filter from modelGravatar Berthold Stoeger
Split out the actual filtering from the MultiFilterSortModel. Create a DiveFilter class that does the actual filtering. Currently, mobile and desktop have their own version of this class, though ultimately we may want to merge them. The idea here is that the trip-model and undo-commands have direct access to the filter-function and thus can take care of keeping track of the number of shown dives, etc. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-11-14Refactoring: move undo commands to top levelGravatar Berthold Stoeger

2019-11-11Cleanup: introduce DiveTripModelBase::IS_TRIP_ROLEGravatar Berthold Stoeger

2019-10-20Cleanup: use pointer-to-member-function in addAction() callsGravatar Berthold Stoeger

2019-09-06Map: highlight correct dive sites in dive site modeGravatar Berthold Stoeger
Since changing the highlighting to use the selected dive, dive sites with no dive were never highlighted in dive site mode. Obviously, because there was no dive to be selected. Therefore special-case all dive-site selection code to recognize when we are in dive site mode. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-09-06Selection: properly update selection flag of map locationGravatar Berthold Stoeger
Owing to the recent changes, when the selection flag in the MapLocationModel was not updated correctly when the user manually selected the dive.

2019-09-06Desktop: show all selected dive sites on clickGravatar Berthold Stoeger
When clicking a dive site on the map, the QML code would set the selected dive site, but then all dives of dive sites in the vicinity were set. But still only the clicked-on dive site was shown. Therefore, don't set the list of selected dive sites in QML, but later in DiveListView::selectDives(), where we know all the dives that were selected. This, again, gives nasty entanglement of diverse widgets and models. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>

2019-07-04Cleanup: avoid spurious updateDiveInfo() callsGravatar Berthold Stoeger
In 2e230da3610dd1fc61badaf328a084512895fb90 the dive-selection signals were unified. Sadly, this was done in a suboptimal way resulting in numerous calls to updateDiveInfo(), which refreshes the main-tab. Firstly, the MainWindow connected to selection changes from both, the undo-command and the divelist. Secondly, every selected dive in the divelist caused a single signal. Thus, connect only to the divelist (this is necessary for user-initiated selection changes) and only send a single signal in the divelist per selection-reset. This is still less than perfect as updateDiveInfo() is called even if the current dive doesn't change. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-06-23Cleanup: unify selection signalsGravatar Berthold Stoeger
For historic reasons, there where three distinct signals concerning dive-selection from the undo-machinery: 1) divesSelected: sent newly selected dives 2) currentDiveChanged: sent if the current dive changed 3) selectionChanged: sent at the end of a command if either the selection or the current dive changed Since now the undo-commands do a full reset of the selection, merge these three signals into a single signal.

2019-06-23Undo: unify selection behavior in dive-list commandsGravatar Berthold Stoeger
Some commands tried to retain the current selection on undo/redo, others set the selection to the modified dives. The latter was introduced because it was easier in some cases, but it is probably more user-friendly because the user gets feedback on the change.
