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.

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
QVector is faster, use it for "m_mapLocations" instead of QList. Signed-off-by: Lubomir I. Ivanov <neolit123@gmail.com>

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.
