2019-09-06Cleanup: remove redundant Roles:: qualifier in maplocationmodel.cppGravatar Berthold Stoeger
"Roles" is a C-style enum (i.e. not C++-style enum class). Since that means that the names spill into the outer namespace, the names themselves are prefixed with "Role". Nevertheless the code qualified the names with "Roles::". This is redundant and unnecessary. Remove this redundancy to show that we understand how the language works. Note: we could also transform the enum into an enum class and remove the "Role" prefix from the names. That would arguably be "cleaner", but then the enum doesn't auto-convert to/from int, but Qt uses int to pass the roles to functions. So let's go the simple way that avoids casting.

2019-09-06Cleanup: remove includes from maplocationmodel.cppGravatar Berthold Stoeger
Neither "QDebug" nor "algorithm" were necessary. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-09-06Cleanup: remove default constructor from MapLocationGravatar Berthold Stoeger
Since this is no longer a Q_METATYPE, nobody will try to default construct this object. Remove the default constructor and guarantee that there will be no null divesite. Of course, the lack of default constructor means that the default argument to the "selected" member variable should be removed. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-09-06Cleanup: remove accessor functions from MapLocationGravatar Berthold Stoeger
Let's face it: this is a value type. No point in having Java-style getters and setters. Replace by plain old and boring member variables. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-09-06Cleanup: remove MapLocation::coordinateChanged signalGravatar Berthold Stoeger
Nobody was listening for that signal. Remove it. This, quite obviously, makse the setCoordinateNoEmit() function redundant. Merge with setCoordinateNoEmit(). Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-09-06Cleanup: remove Q_PROPERTIEs from MapLocationGravatar Berthold Stoeger
We never dish out an object of this type to QML. It is unclear how Q_PROPERTIEs could be of any use. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-09-06Cleanup: remove MapLocationModel::count() and the attribute countGravatar Berthold Stoeger
These were not used anywhere and the function was redundant [same result as rowCount()]. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-09-06Cleanup: remove MapLocationModel::get() functionGravatar Berthold Stoeger
It was not called anymore. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-09-06Cleanup: remove MapLocationModel::isSelected() functionGravatar Berthold Stoeger
That function was replaced by a model-attribute. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-09-06Map: export isSelected as attribute from MapLocationModelGravatar Berthold Stoeger
Recently we changed the MapLocationModel-items to store whether they are selected. Thus, we can directly export an isSelected flag instead of calling a function taking a dive-site argument. 1) This makes the QML easier to read. 2) This avoids passing pointers through QML which has caused us lots of pain.

2019-09-06Cleanup: simplify role handling in MapLocationModelGravatar Berthold Stoeger
To connect a model to QML, one is supposed to provide a QHash<int, QByteArray> MapLocationModel::roleNames() function that returns a role -> attribute-name hash. That was realized by filling the hash in the constructor, storing it as a member variable, using static strings that were declared in the class-definition and defined in the translation unit. Adding a new role was a pain and the whole thing was totally pointless as the attribute names were used nowhere else and the roleNames() function is called only once. Simply do, what we do everywhere else: initialize the hash in the roleNames() function and use normal string literals. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-09-06Map: calculate the z value in the modelGravatar Berthold Stoeger
Since not fully reloading the map on selection change, the selected sites were not moved to the top. Not calculating the z-value in QML, but making it a simple model property helps. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
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>
2019-09-06Map: don't fully reset model on selection changeGravatar Berthold Stoeger
When changing the selection the MapLocationModel was reset. This lead to crashes on Qt-5.9 which are due to QML accessing data that was freed during model reset. This putative Qt bug doesn't happen on newer Qt versions. At least Qt-5.12 is known to work. Instead of fighting the bug, let's simply not reset the model but send a dataChanged() for every element of the MapLocationModel. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-09-06Map: generate pixmap name in modelGravatar Berthold Stoeger
Experimentation has shown that the image of a flag will only be changed after dataChanged() if it is a simple property. The old code had a complex QML expression and then - for some reason - it didn't work. To give us better control over the flags and avoid full reloads of the map therefore introduce a model-property pixmap name. The name depends on whether the site is selected and if not, whether we are in divesite-edit mode. This makes the code rather convoluted. Firstly, we have to save whether the site is selected in the map-item. Secondly we have to access the global map-widget, which in turn has to go to the map-widget helper (layering violation!).

2019-09-06Map: explicitly reload selected map on clickGravatar Berthold Stoeger
When clicking on a flag 1) The QML would call MapLocationModel::setSelected() with fromClick = true 2) MapLocationModel::setSelected() would emit a signal selectedLocationChanged() 3) MapWidgetHelper would catch that signal and do the actual processing. Other functions would call MapLocationModel::setSelected() with fromClick = false, which would not emit the selectedLocationChanged() signal. Detangle this a bit by calling the selectedLocationChanged() function directly from QML and remove the fromClick parameter. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-08-28Map: catch null divesites in map widget selection codeGravatar Berthold Stoeger
Just to be sure, refuse to add null divesites to the selection. Moreover, refuse to call the setSelected function on a null-divesite. I got an unfriendly Qt-Warning there: "Passing incompatible arguments to C++ functions from JavaScript is dangerous and deprecated." "This will throw a JavaScript TypeError in future releases of Qt!"

2019-07-27Crash fix: prevent crash in MapLocationModel::reloadGravatar Berthold Stoeger
Commit 0c387549164d7eec3ea6647c54ada2fba7f8d5e6 introduced a bug in MapLocationModel::reload() by setting an entry in the name-to-location map before the location was initialized. Move the setting of the map entry back where it was before: after the assignment of the location variable. Moreover, define the location variable directly on allocation of the location to avoid thus bugs in the future. Why did we not get a "might be used unitialized" warning anyway?

2019-05-11Map: automatically update names on the mapGravatar Berthold Stoeger
Currently, dive site names are only updated on full reload. Instead hook directly into the corresponding signal in the MapLocationModel to set the name. Also to the coordinates directly there instead of going via the MapWidgetHelper. In the MapWidgetHelper, just center on the changed dive site. Hook into the signal directly there and remove the slot from the MapWidget. This makes the whole call-chain at least one call shorter. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-05-11Map: in edit mode place no-gps dive sites at center of mapGravatar Berthold Stoeger
Move the code to add the first selected dive site from MapWidgetHelper::enterEditMode() to MapLocationModel::reload(). Thus, the list of sites is built only at one place. For this it is necessary to pass a pointer to the map, so that new dive sites can be added at the center of the map. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-05-11Map: construct list of dive sites from dive site tableGravatar Berthold Stoeger
Instead of looping over the dive table and extract dive sites, loop over the dive site table. This makes it possible to show dive sites that have no dive associated with them. But we have to create to functions that check whether a dive site has any shown dives or has any selected dives. Moreover, change the code to add near dive sites of the same name if in edit mode. Other wise (erroneously added?) dive sites with the same name cannot be moved on the map. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-05-11Map: in dive-site-edit mode, select those maps we filter forGravatar Berthold Stoeger
When dive sites are edited, we shouldn't highlight the sites of the current dive, but the currently edited site(s). Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-05-11Map: make edit mode depend on dive-site-filteringGravatar Berthold Stoeger
Since the dive-site-filter is active either on the dive-site-edit page or the dive-site-list page, use that as the flag for dive-site-edit mode. Moreover, when the filter is reset, the MapWidgetHelper::reloadMapLocations() function is called, so we can use that place to enter/exit edit mode. This makes it easier to keep everything consistent. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-05-11Map: show multiple selected dive sitesGravatar Berthold Stoeger
If multiple dives are selected, highlight all corresponding sites. For that, replace the MapLocationModel::m_selectedDs pointer by a QVector<>. Fill the vector in MapLocationModel::reload() and add a isSelected() member function. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-05-11Map: move calculation of list from map-helper to map-modelGravatar Berthold Stoeger
The map model keeps track of the dive site positions on the map. Therefore, it seems more logical to have the code calculating the map position in the model, not in the helper-class. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2019-03-15Map: create correct index in updateMapLocationCoordinates()Gravatar Berthold Stoeger
When updating the coordinates of a dive site, the MapLocationModel is updated. The code created a (col, row) index with col = 0. [The idea of course being col = x, row = y]. Alas, that's not how Qt works - its models want (row, col) indices. The code worked, because the only time when the dive site locations were updated was in dive site edit mode, when only one site is visible, i.e. there is only one row leading to the correct (0, 0) index. Fix this so that we can also change dive site positions if more than one site is displayed. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-10-29Dive list: don't pass dive_site via uintptr_t through QMLGravatar Berthold Stoeger
Now that struct dive_site * is a proper Q_METATYPE it is not necessary anymore to pass dive-sites as opaque uintptr_t types. Simply pass a QVariants or directly via dive_site *. 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>

2017-11-09map-widget: allow real-time updates of edited markersGravatar Lubomir I. Ivanov
This patch allows updating the location of map markers while editing a dive site and updating the text in the LocationInformationWidget in real-time. Currently it is only possible to see the marker changes by clicking 'Apply'. The modification required the following changes: - add the MapWidget::updateCurrentDiveSiteCoordinatesToMap() slot and call it each time the GPS text updates - separate the updateCurrentDiveSiteCoordinates(FromMap/ToMap) logic by having the FromMap/ToMap suffix to method names - make MapWidgetHelper::updateCurrentDiveSiteCoordinatesToMap() call a new MapLocationModel::updateMapLocationCoordinates() method, which updates selected location coordinates and the model - add MapLocation::setCoordinateNoEmit() that does not emit a signal when updating a coordinate Signed-off-by: Lubomir I.

2017-07-28maplocation: add helpers for coordinate and uuidGravatar Lubomir I. Ivanov
getRole() returns a QVariant and the cast is a small overhead. Using these helpers will reduce the overhead. Signed-off-by: Lubomir I. Ivanov <neolit123@gmail.com>
2017-07-28maplocationmodel: add the "namer" propertyGravatar Lubomir I. Ivanov
The MapLocation QObject now has a QString property "name", which is translating the dive_site->name member. Signed-off-by: Lubomir I. Ivanov <neolit123@gmail.com>
2017-07-28maplocationmodel: make setSelectedUuid() accept "fromClick" flagGravatar Lubomir I. Ivanov
The idea of this flag is to be able to only to emit the selectedLocationChanged() signal when the user clicked on the map (fromClick == true). MapWidgetHelper::selectedLocationChanged() listens for this signal and only then it will select nearby dives based on a "small-cicle". If "fromClick" is false, it's the backend or the dive list that updated the selection and MapWidgetHelper::selectedLocationChanged() should no be called. Signed-off-by: Lubomir I. Ivanov <neolit123@gmail.com>
2017-07-28maplocationmodel: add the helper method getMapLocationForUuid()Gravatar Lubomir I. Ivanov
getMapLocationForUuid() accepts a UUID, searches the MapLocation table and returns a pointer. Make use of the new method in setSelectedUuid(). Signed-off-by: Lubomir I. Ivanov <neolit123@gmail.com>
2017-07-28maplocationmodel: add a "selectedUuid" property to MapLocationModelGravatar Lubomir I. Ivanov
Inside the QML Map class there is a MapItemView item. This item uses a delegate that receive a "model" property from the MapLocationModel, but infact that's a QObject with the MapLocation defined properties. That's how MapItemView works. The problem here is that "model" QObject cannot be cast back to a MapLocation as the meta data in there does not include a MapLocation sub-class, for some reason. Even if using propery() on that QObject to fetch data like coordinates works, instead of storing this strange object pointer, store the MapLocation UUID (from dive_site) which is a uint32_t. setSelectedUuid() deals with this oddity and finds the correct MapLocation pointer in the table and dispatches a selectedLocationChanged() signal for it. Signed-off-by: Lubomir I. Ivanov <neolit123@gmail.com>
2017-07-28maplocationmodel: add a "uuid" property to MapLocationGravatar Lubomir I. Ivanov
The "uuid" property will be the one from the dive_site. At first it will also be used to track the active marker/flag selection. Signed-off-by: Lubomir I. Ivanov <neolit123@gmail.com>
2017-07-28maplocationmodel: use QVector for the MapLocation storageGravatar Lubomir I. Ivanov

2017-07-28maplocationmodel: add the addList() methodGravatar Lubomir I. Ivanov
This method should be used if many markers are added at once. It's main purpose is to reduces the number of beingInsertRows() calls. Make MapWidgetHelper::reloadMapLocations() use it. Signed-off-by: Lubomir I. Ivanov <neolit123@gmail.com>
2017-07-28maplocationmodel: store the coordinate as QGeoCoordinateGravatar Lubomir I. Ivanov
Instead of maintaining a seperate latitude/longitude values in C++ and passing them to QML separatelly, pass them as a QGeoCoordinate. This reduces the number of model "roles" and also prevents the creations of extra objects in QML (e.g. via QtPositioning.coordinate(..)). Signed-off-by: Lubomir I. Ivanov <neolit123@gmail.com>
2017-07-28maplocationmodel: implement the clear() and add() methodsGravatar Lubomir I. Ivanov
- add() will be used to add a MapLocation to the model with beginInsertRows()...endInsertRows() - clear() will be used to clear the model with beginRemoveRows()... endRemoveRows() NOTE: emiting dataChanged() does not seem to update the QML view for this model so calling being<..>Rows() seems to be the "correct Qt approach" to do this.

2017-07-28qt-models/maplocationmodel: add new classes for map model based handlingGravatar Lubomir I. Ivanov
The QML Map widget requires a QAbstractListModel based model to operate with good performance. Technically gpslistmodel.cpp can be used for that same purpose (e.g. has GPS coordinates), but the way it updates may complicate the Map widget integration. Thus, a new model is created - MapLocationModel, with items of type MapLocation, for an attempt for a clean project structure on the C++ side. For now it only handles latitude and longitude.
