2019-01-19Import: control process_imported_dives() by flagsGravatar Berthold Stoeger
process_imported_dives() takes four boolean parameters. Replace these by flags. This makes the function calls much more descriptive. Morover, it becomes easier to add or remove flags. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-01-19Import: add add_to_new_trip flag to process_imported_dives()Gravatar Berthold Stoeger
If this flag is set, dives that are not assigned to a trip will be assigned to a new trip. This flag is set if the user checked "add to new trip" in the download dialog of the desktop version. Currently this is a no-op as the dives will already have been added to a new trip by the downloading code. This will be removed in a subsequent commit.

2019-01-09Cleanup: remove explicit constructor of DiveListBaseGravatar Berthold Stoeger
DiveListBase had an explicit constructor that initialized the "firstExecution" member variable. The latter was a development- artifact that was never used. Remove the member and the constructor. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-01-09Undo: make dive-import undoableGravatar Berthold Stoeger
On desktop, replace all add_imported_dives() calls by a new undo-command. This was rather straight forward, as all the preparation work was done in previous commits. By using an undo-command, a full UI-reset can be avoided, making the UI react smoother. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-01-09Undo commands: refactor dive-trip handlingGravatar Berthold Stoeger
Trips were added to the core with the first dive of that trip. With the recent changes that keep trips ordered by first dive, this became counter-productive. Keeping a consistent state at all times would mean resorting the trip table for every dive that is added. Instead, add all dives to a trip and *then* add the trip to the core. Change the data-structures to not register trips-to-be-added with individual dives, but keep them in a separate vector for each undo command.

2018-10-11Undo: make adding of planned dive undo-ableGravatar Berthold Stoeger
Planned dives were still added by directly calling core code. This could confuse the undo-machinery, leading to crashes. Instead, use the proper undo-command. The problem is that as opposed to the other AddDive-commands, planned dives may belong to a trip. Thus, the interface to the AddDive command was changed to respect the divetrip field. Make sure that the other callers reset that field (actually, it should never be set). Add a comment describing the perhaps surprising interface (the passed-in dive, usually displayed dive, is reset). Moreover, a dive cloned in the planner is not assigned a new number. Thus, add an argument to the AddDive-command, which expresses whether a new number should be generated for the to-be-added dive.

2018-10-11Undo: use vectors for MergeDives and SplitDiveGravatar Berthold Stoeger
The MergeDives and SplitDive commands used addDive() and removeDive() calls to manage their dives. Unfortunately, these calls don't send the proper signals and thus the dive-list was not updated. Instead, use one- and two-element vectors, which are passed to addDives() and removeDives() [note the plural]. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-10-11Undo: select dives after add, remove, merge, split dive commandsGravatar Berthold Stoeger
Select the proper dives after the add, remove, split and merge dives commands on undo *and* redo. Generally, select the added dives. For undo of add, remember the pre-addition selection. For redo of remove, select the closest dive to the first removed dive. The biggest part of the commit is the signal-interface between the dive commands and the dive-list model and dive-list view. This is done in two steps: 1) To the DiveTripModel in batches of trips. The dive trip model transforms the dives into indices. 2) To the DiveListView. The DiveListView has to translate the DiveTripModel indexes to actual indexes via its QSortFilterProxy- model. For code-reuse, derive all divelist-changing commands from a new base-class, which has a flag that describes whether the divelist changed. The helper functions which add and remove dives are made members of the base class and set the flag is a selected dive is added or removed. To properly detect when the current dive was deleted it became necessary to turn the current dive from an index to a pointer, because indices are not stable. Unfortunately, in some cases an index was expected and these places now have to transform the dive into an index. These should be converted in due course.

2018-10-11Undo: use dive * instead of unique index in renumber-divesGravatar Berthold Stoeger
Now, that pointers to dives are stable, we might just as well use dive * instead of the unique-id. This also affects the merge-dive command, as this uses the same renumbering machinery. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-10-11Undo: implement autogrouping of trips in DiveAddGravatar Berthold Stoeger
If the autogroup flag is set, search for appropriate trips in DiveAdd() and add the dive to this trip. If no trip exists, add a new trip. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-10-11Dive list: implement proper Qt-model semantics for DiveTripModelGravatar Berthold Stoeger
Previously, each dive-list modifying function would lead to a full model reset. Instead, implement proper Qt-model semantics using beginInsertRows()/endInsertRows(), beginRemoveRows()/ endRemoveRows(), dataChange(). To do so, a DiveListNotifer singleton is generatated, which broadcasts all changes to the dive-list. Signals are sent by the commands and received by the DiveTripModel. Signals are batched by dive-trip. This seems to be an adequate compromise for the two kinds of list-views (tree and list). In the common usecase mostly dives of a single trip are affected. Thus, batching of dives is performed in two positions: - At command-level to batch by trip - In DiveTripModel to feed batches of contiguous elements to Qt's begin*/end*-functions. This is conceptually simple, but rather complex code. To avoid repetition of complex loops, the batching is implemented in templated-functions, which are passed lambda-functions, which are called for each batch.

2018-10-11Undo: isolate undo-commandsGravatar Berthold Stoeger
This refactors the undo-commands (which are now only "commands"). - Move everything in namespace Command. This allows shortening of names without polluting the global namespace. Moreover, the prefix Command:: will immediately signal that the undo-machinery is invoked. This is more terse than UndoCommands::instance()->... - Remove the Undo in front of the class-names. Creating an "UndoX" object to do "X" is paradoxical. - Create a base class for all commands that defines the Qt-translation functions. Thus all translations end up in the "Command" context. - Add a workToBeDone() function, which signals whether this should be added to the UndoStack. Thus the caller doesn't have to check itself whether this any work will be done. Note: Qt5.9 introduces "setObsolete" which does the same. - Split into public and internal header files. In the public header file only export the function calls, thus hiding all implementation details from the caller. - Split in different translation units: One for the stubs, one for the base classes and one for groups of commands. Currently, there is only one class of commands: divelist-commands. - Move the undoStack from the MainWindow class into commands_base.cpp. If we want to implement MDI, this can easily be moved into an appropriate Document class.
