* Port Map*ObjectPrivateQSG to the shader-based projection geometriesv5.15.0-alpha1Paolo Angelelli2020-02-111-2/+1
| | | | | | | | | | | | | | | | | | | | | | | This patch changes the implementation of the scenegraph-based mapobjects (those created by QGeoTiledMap) to be the recently introduced one sporting shader-based map projection. This is much faster than the previous, but may introduce small glitches at this time (mostly on minified polylines). Adding polyline LOD simplification will solve this problem. Compared to equivalent Map Items (that is, Map Items backed by the same underlying implementation), map objects now are approximately 1.5x faster. This measure has been gathered using medium-size polygons (contained in the file 10_countries.json from the geojson_viewer example). The difference is caused by the additional QtQuick geometry related operations (essentially projecting the bounding box for each item) present in MapItems. Smaller polygons may therefore yield larger improvements, larger polygons the opposite. Change-Id: I3fc92b02b74a3a4d001e69755949a98f80d8a3d3 Reviewed-by: Alex Blasche <alexander.blasche@qt.io>
* Fix MapObjects ::border property not properly initializedPaolo Angelelli2020-01-141-1/+1
| | | | | | | This patch also parents it with the object also fixing memory leaks. Change-Id: I74a21176b1d2450b10a21f92321520ca2c6e88e0 Reviewed-by: Alex Blasche <alexander.blasche@qt.io>
* Introduce QGeoMapObject::geoShape propertyPaolo Angelelli2019-02-011-4/+39
| | | | | | | | | | In this way MapObjects become a little closer to MapItems, and this property can be used to, for example, center the map on one specific object or object group.

* Fix QGeoMapObject handling in reference implementationPaolo Angelelli2018-04-221-1/+2
| | | | | | | | | | | | | | | | | setVisible was neither changing the visibility nor triggering repaint. Pimpls weren't removing themselves in their destructors when dynamically added/removed via QGeoMapObjectView add/removeMapObject. This patch also factors out the duplicated QGeoMapObject support from QGeoTiledMapLabs and QGeoMapObjectsOverlay and moves it into an own class, QGeoMapObjectQSGSupport. To properly flush the scene graph nodes upon object removal, a pointer to the QSGNode is added to the MapObject struct, now moved inside QGeoMapObjectQSGSupport.

* Move locationlabs code into locationPaolo Angelelli2018-03-231-0/+217
The labs feature will still be controlled by location-labs-plugin config option. They will simply come from the QtLocation module, and be exposed to QML via the additional qml plugin in imports/locationlabs.
