2019-02-19Filter: implement any-of modeGravatar Berthold Stoeger
Add an additional mode to the tags, people and location filters: any_of. Replace the original invert-bool by an enum. Move the common code into a distinct function. Reported-by: Willem Ferguson <willemferguson@zoology.up.ac.za> Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-01-26Filter: quick implementation of negationGravatar Berthold Stoeger
Add negate buttons to the Tags, People, Location and Equipment filters. Currently, if nothing is entered the filter is ignored whether negate is on or off. One might think about filtering all dives without tags, etc. instead. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-01-26Filter: update counts if dives added / removedGravatar Berthold Stoeger
Update the filter counts if dives were added removed by the undo commands. The undo commands call into the filter model at the right time so that hidden_by_filter is already set. The filter model keeps track of the counts and emits a signal, which is caught by the widget. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-01-22Filter: support imperial unitsGravatar Berthold Stoeger
1) Choose the correct conversion function for comparison. 2) Add a unit suffix to the fields. 3) Update the suffixes on change of preferences. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-01-21Desktop, Filter UI: make date/time consistentGravatar Jan Mulder
On all (most?) places we use separate date/time fields for the time of a dive, and we follow the setting from the preferences to format those. Make the new filter widget consistent, with respect to the to and from interval. Signed-off-by: Jan Mulder <jlmulder@xs4all.nl>
2019-01-19Filter: make tags, people and location filter logically-andGravatar Berthold Stoeger
If the user provides multiple tags, they probably want to search for dive with *all* of these tags. Replace the convoluted loops by std::all_of(). This makes it trivial to change logically-and to logically-or: Replace std::all_of() by std::any_of().

2019-01-19Filter: reinstate dive-site filter functionalityGravatar Berthold Stoeger
Commit 201f0c8f89d6d7df96fd220ea2c0d0977c9b7f20 removed the dive-site filtering. This is needed for dive-site editing: The list should only show dives at the corresponding dive-site. As opposed to the original code, only compare for the actual dive-site, not for the name of the dive-site. The reason for comparing dive-site names is unknown. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-01-19Filter: ignore unset temperaturesGravatar Berthold Stoeger
The filter treated unset air and water temperatures as 0 K, leading to many dives not being shown. Don't filter on unset temperatures. Reported-by: Jan Mulder <jlmulder@xs4all.nl> Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-01-19Filter: update filterData directly without copyingGravatar Berthold Stoeger
In FilterWidget2::updateFilter() a new FilterData object is generated and then copied onto the filterData member variable. Instead, modify filterData directly. This seems also more logical from a semantic point of view: Do we want to reset fields that were not set by the user? Contains trivial whitespace fix. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-01-08Filter for logged/planned divesGravatar Robert C. Helling
Add filter for dives having a planned dive computer or a logged dive computer. Signed-off-by: Robert C. Helling <helling@atdotde.de>
2019-01-07Dive list: split DiveTripModel into distinct models (tree and list)Gravatar Berthold Stoeger
The DiveTripModel was used to represent both, trip and list views. Thus many functions had conditionals checking for the current mode and both modes had to be represented by the same data structure. Instead, split the model in two and derive them from a base class, which implements common functions and defines an interface. The model can be switched by a call to resetModel(), which invalidates any pointer obtained by instance(). This is quite surprising behavior. To handle it, straighten out the control flow: DiveListView --> MultiFilterSortModel --> DiveTripModelBase Before, DiveListView accessed DiveTripModelBase directly. A goal of this commit is to enable usage of the same model by mobile and desktop. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-01-07Cleanup: Remove MultiFilterSortModel::modelGravatar Berthold Stoeger
The source-model was cached in MultiFilterSortModel. For simplicity, remove that and simply access via DiveTripModel::instance(). There is only one instance where the cached model was used: when comparing items for sorting. Thus, in indirection is added in a "hot" path. Nevertheless, this will dwarf against the cost of string comparison. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-12-14Hide unimplemented components from searchGravatar Tomaz Canabrava

2018-12-14Filter the dataGravatar Tomaz Canabrava
Wire up the needed code to filter the data in the myInvalidate call. The data comes from the Struct FilterData and if any of the test conditions on the filter function are false, the filter will assume that the specific dive shouldn't be shown Signed-off-by: Tomaz Canabrava <tcanabrava@kde.org>

Drop tons of now-unused-code. Signed-off-by: Tomaz Canabrava <tcanabrava@kde.org>
2018-12-14Struct FilterDataGravatar Tomaz Canabrava
The idea is that this struct will have all the needed data that will be passed to the filter model. Everything that happens on the filterwidget will fill out this struct, then forward it to the model, that in turn will activate the filter hiding some of the dives that matches on your divelist. Signed-off-by: Tomaz Canabrava <tcanabrava@kde.org>
2018-11-23Cleanup: make "struct dive *" and "struct dive_trip *" Qt metatypesGravatar Berthold Stoeger
Just as we did for pointer to struct dive_site, make pointers to struct dive and struct dive_trip "Qt metatypes". This means that they can be passed through QVariants without taking a detour via void *. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-11-18Dive list: replace dive-list of trips by a tableGravatar Berthold Stoeger
The dives of each trip were kept in a list. Replace this by a struct dive_table. This will make it significantly easier to keep the dives of a trip in sorted state. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-11-01Dive list: implement custom lessThan functionGravatar Berthold Stoeger
The dive list was sorted using the default-sorter of QSortFilterProxy model. This is mighty inflexible as it considers only one column. This has the funky effect that for rows with identical elements, the sort order depends on the previous sorting. Implement a lessThan() function in the MultiFilterSortModel, which simply hands the sorting down to the actual model. This might be considered a layering violation, but it makes things so much easier. Sadly, it seems like the column-to-be-sorted is transported in the provided indices. Therefore, the comparison is chosen using a switch for *every* comparison. It would seem much more logical to set a function pointer once and use that. Further investigations are necessary.

2018-11-01Dive list: make filter model aware of its sourceGravatar Berthold Stoeger
The data-flow from C-core to list-view is as follows: C-core --> DiveTripModel --> MultiSortFilterModel --> DiveListView The control-flow, on the other hand, differs as DiveListView accesses both MultiSortFilterModel and DiveTripModel, whereas MultiSortFilterModel is mostly unaware of its source model. This is in principle legitimate, as the MultiSortFilterModel might be used for different sources. In our particular case, this is not so. MultiSortFilterModel is written for a particular use case. Therefore, model control-flow follow after data-flow: Let MultiSortFilterModel set its own source model and DiveListView access the MultiSortFilterModel, which then manages its source model. This is not bike-shedding, but will enable a more flexible and higher-performance sorting. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-10-29Dive site: compare pointers in MultiFilterSortModel::showDive()Gravatar Berthold Stoeger
To test whether to show a dive, the UUIDs of the filtered-by location and the dive-site of a dive were compared. Since UUIDs are unique (as the name implies), directly compare pointers. Note: this code comes from a time when the filtered-by location was not a pointer, but a copy. Moreover, the if tested first for the same name, then (logical-or) for the same uuid. This makes no sense, as the same dive-site implies the same name. This code likewise can be explained by historic reasons: the filtered-by location may have contained a different name. Swap the order of the conditions: first test for the same object and only of the objects differ, test for the same same. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-10-29Dive site: replace dive->dive_site_uuid by dive_siteGravatar Berthold Stoeger
Replace the UUID reference of struct dive by a pointer to dive_site. This commit is rather large in lines, but nevertheless quite simple since most of the UUID->pointer work was done in previous commits. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-10-29Dive site: remove [start|stop]FilterDiveSite signalsGravatar Berthold Stoeger
This is another case of a weird pattern where an object would connect it's own signal to the slot of a different object. There seems to be no reason why the former couldn't simply call the latter. Remove the [start|stop]FilterDiveSite signals of LocationInformationWidget and call the corresponding functions of MultiFilterSortModel directly. While doing so, replace the UUID argument by a pointer-to-divesite. It will be converted anyway right at the beginning of the function. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-10-21Dive list: move dive-selection code from filter to listGravatar Berthold Stoeger
After invalidating the filter, the dive-selection was modified to ensure that at least one dive is selected. This was done in the filter code, but it seems preferrable to do this in the dive-list code, which has direct access to the selection-model. Therefore, move the code from MultiFilterSortModel to DiveListView. While doing so, split the code in DiveListView into more functions to: 1) Get the index of the first dive (if any). 2) Select the first dive (if any). This allows a distinct size reduction of conditional compilation in MultiFilterSortModel (accesses to MainWindow are not possible in mobile code). Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-10-13Cleanup: rename MainWindow member variablesGravatar Berthold Stoeger
Instead of the weirdly named "information" and the inconsistent "dive_list" use the logical "mainTab" and the camel-cased "diveList", respectively. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-10-13Cleanup: Turn widget accessor-functions into simple pointersGravatar Berthold Stoeger
The keeps track of different sub widgets needed by other parts of the code, notably: MainTab PlannerDetails PlannerSettingsWidget ProfileWidget2 DivePlannerWidget DiveListView Access to these widgets was provided with accessor functions. Now these functions were very weird: instead of simply returning pointers that were stored in the class, they accessed a data structure which describes the different application states. But this data structure was "duck-typed", so there was an implicit agreement at which position the pointers to the widgets were put inside. The widgets were then down-cast by the accessor functions. This might make sense if the individual widgets could for some reason be replaced by other widgets [dynamic plugins?], but even then it would be strange, as one would expect to get a pointer to some base class. Therefore, directly store the properly typed pointers to the widgets and simply remove the accessor functions. Why bother? Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-10-11Filter: reload only when checkstate changedGravatar Berthold Stoeger
Currently, the filter is recalculated if a filter-entry is changed. This also happens if the counts of a filter-entry changes. This is to be avoided, as it causes unnecessary churn. Therefore, send the proper role with the dataChanged() signal and add a new slot, which invalidates only if a field with the Qt::CheckStateRole is changed. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-10-11Filter: Make filters aware of added / removed divesGravatar Berthold Stoeger
Instead of reloading all the filter, only increment / decrement the count of the entries of added / removed dives. Originally, this was planned to be done via the signals from the divelist, but it turned out that this was suboptimal, because if the filter decides that the new item is selected, this has to be done *before* adding the dive. Otherwise, it wouldn't be shown. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-08-31Filter: sort filter items in FilterModelBase::updateList()Gravatar Berthold Stoeger
All callers of FilterModelBase::updateList() sorted the items (except the last one). Thus we can do the sorting inside the function. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-08-31Filter: Make FilterModelBase a proper Qt model (mostly)Gravatar Berthold Stoeger
Since FilterModelBase now contains complex data (counts and checked), we might just as well make it a full model and keep track of the name as well. I.e. do not derive from QStringListModel but from QAbstractListModel and add the name to the item structure. Implement proper reset / add / rename semantics. This is overkill at the moment, as after all any modification the model will be reset, but ultimately it will allow us to be smarter and only update rows when needed. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-08-28Filter: cache number of dives fulfilling filter rulesGravatar Berthold Stoeger
Currently, in FilterModelBase::data() the number of dives is recalculated. This happens for every mouse-over event! Calculate the number of dives only on recalculation and store the count in the items-struct. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>

2018-08-28Filter: replace checked-state by structGravatar Berthold Stoeger
In the future, we might be smarter about the dive-counts and calculate them only once and incrementally (if e.g. new dives are added). Prepare for more complex caching by turning the checked boolean into a struct, which can then be extended by a count and other things (e.g. the name). Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-08-16Filter: separate backend from frontend logicGravatar Berthold Stoeger
The filter code was an unholy intermixture of backend and frontend logic, which made it hard to access it from outside of the UI. Notably, it expected that Qt would call filterAcceptsRow on all rows. For trip-view, apparently the filter functions were called twice (once for filtering the trip, then for filtering the individual dives). Make the filtering explicit, by calling showDive() for all dives in MultiFilterSortModel::myInvalidate(), setting the hidden_by_filter flags accordingly and ultimately invalidating the filter. The UI code only accesses the hidden_by_filter flag set previously. The "justCleared" flag can then be removed, since accessing the filter does not have side effects. Moreover, there is no noticeable performance gain by returning out early. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-08-14Filter: break out showDive() function from filterAcceptsRow()Gravatar Berthold Stoeger
To make dive-filtering accessible from other parts of the code, break out the actual dive-filtering code into a function that takes a pointer-to-dive instead of QModelIndex. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-08-14Filter: constify doFilter() argumentGravatar Berthold Stoeger
Conceptually, the doFilter() functions shouldn't modify the dive they test. Therefore, make the argument const. To do this, constify the parameter of get_dive_location(), which likewise seems to be the right thing to do. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-08-14Filter: remove unused parameters from doFilter functionsGravatar Berthold Stoeger
Change the signature from of the virtual doFilter() functions from bool doFilter(struct dive *d, QModelIndex&, QAbstractItemModel*) const; to bool LocationFilterModel::doFilter(struct dive *d) const; as the QModelIndex and QAbstractItemModel parameters were not used. This makes this functions independent from Qt's model/view framework. This is in preparation for making the undo-machinery compatible with the filtering. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-07-30Cleanup: remove DiveListView::fixMessyQtModelBehaviour()Gravatar Berthold Stoeger
The function DiveListView::fixMessyQtModelBehaviour() was used to expand the first columns of dive-trips in the dive-list view. This function was called everytime that the dive-list was modified. It is kind of ludicrous that external callers would have to tell the DiveListView, when it has to update its column headers. Instead, place this functionality in the overriden reset() and rowsInserted() functions, as these are the only ways that rows can be added. Change the DiveTripModel to use the proper beginResetModel()/endResetModel() pair instead of the previous full deletion and full repopulation using the beginRemoveRows()/ endRemoveRows() and beginInsertRows()/endInsertRows().

2018-03-14Cleanup: consistently use qPrintable()Gravatar Berthold Stoeger
Replace constructs of the kind s.toUtf8().data(), s.toUtf8().constData(), s.toLocal8Bit().data(), s.toLocal8Bit.constData() or qUtf8Printable(s) by qPrintable(s). This is concise, consistent and - in principle - more performant than the .data() versions. Sadly, owing to a suboptimal implementation, qPrintable(s) currently is a pessimization compared to s.toUtf8().data().

2017-12-28cleanup: Argument cannot be negativeGravatar Jan Mulder
CID 208296. IndexOf can return -1 when not found, which will not happen in this context, so just to silence Coverity. Signed-off-by: Jan Mulder <jlmulder@xs4all.nl>
2017-12-28filter: fix trip header bugGravatar Jan Mulder
With commit 5962f00679fae555, a well known problem was introduced. Incorrect width setting for the spanning trip lines. And as there is even a specific functon for that, just call this. The reason the mentioned commit introduces this, is that invalidate() causes layoutChanged signals, and invalidateFilter() does not. Signed-off-by: Jan Mulder <jlmulder@xs4all.nl>
2017-12-28filter: setStringList() at end of every changeGravatar Jan Mulder
This is mainly code maintenance. Instead of emitting explicit dataChanged signals, we can make sure that setStringList() is called after all model data manipulation is ready. Accoording to the Qt docs: "The model will notify any attached views that its underlying data has changed". In itself, this does not solve the tripped assert mentioned in commit 5962f00679fae5, but this calling at the end just feels better. Signed-off-by: Jan Mulder <jlmulder@xs4all.nl>
2017-12-28filter: prevent assert trap on exit filtersGravatar Jan Mulder
This "bug" is found using Qt 5.10 compiled in developer mode. Access the filers, click a little around here, close the filters. Almost every time the following assert is triggered: ASSERT failure in QPersistentModelIndex::~QPersistentModelIndex: "persistent model indexes corrupted", file itemmodels/qabstractitemmodel.cpp, line 643 This is relatively deep down in Qt, and it is triggered by clearing the filters. Trying to force a crash when using the same scenario in Qt 5.10 compiled for production (so no active asserts) did not result in a crash. So, upto this time, it is unclear if the Qt assert points out a real problem, or it is some false alarm (for whatever reason). Further investigation shows that the assert can be solved by changing the invalidate() to an invalidateFilter(). Indeed, the last variant is a little more lightweigt, and does seem to do the same job from a functional point of view (in this case). Signed-off-by: Jan Mulder <jlmulder@xs4all.nl>
2017-12-28Remove unnecessary dynamic_cast<>s in filter codeGravatar Berthold Stoeger
FilterModelBase is a direct subclass of QAbstractItemModel. Therefore, dynamic_cast<>ing the former to the latter is unnecessary. Probably an artifact of previous code. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2017-12-26Introduce negate-toggle buttons to filter listsGravatar Berthold Stoeger
Introduce toggle buttons which mean "filter all dives except those fulfilling the selected criteria". The old code used to check for rowCount() == 0. This should never happen, because there is always a row "empty field". This check was moved into the preamble of the functions to seperate it from the actual logic. Fixes #435 Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2017-12-24Small whitespace updatesGravatar Dirk Hohndel
