In main. In the main function, we first instantiate a QGuiApplication object. Then we create a QQmlApplicationEngine and tell it to load main. Finally, QGuiApplication::exec launches the main event loop.

Next, we create the top level window, set a sensible default size, and make it visible. The window will be filled by a Map item showing the map.

The Plugin item is necessary to define the map provider we are going to use. The example can work with any of the available geo services plugins. However, some plugins may require additional plugin parameters in order to function correctly and we can use PluginParameter to specify them. In this example, we use the osm plugin, which is a Qt Location Open Street Map Plugin and does not require any parameters. In the Map item, we refer to the plugin we use and we set the center and the zoomLevel of the map.

The example requires a working internet connection to download OpenStreetMap map tiles. An optional system proxy should be picked up automatically. Documentation contributions included herein are the copyrights of their respective owners.

To prevent these changes, either a different geo service plugin should be used, or the plugin parameter osm. Previous versions did not require a prefix. Note: Setting the mapping. On systems that have no concept of a shared cache, the application-specific QStandardPaths::CacheLocation is used instead.

There is no default value, and if this property is not set, no directory will be indexed and only the network disk cache will be used to reduce network usage or to act as an offline storage for the currently cached tiles. The following example shows how to create an OSM plugin instance with parameters supplied for an useragent, and if necessary, a custom server url plus the corresponding copyright information for the tile provider.

Additionally, it is possible to choose another routing server than the public osrm one. Documentation contributions included herein are the copyrights of their respective owners.

Parameter Description osm. This parameter should be set to a value that uniquely identifies the application. Note that providers might block applications not setting this parameter, leaving it to the stock plugin user agent e.

This parameter should be set to a valid server url offering the correct osm API. To use this server, the Map::activeMapType parameter of the Map should be set to the supported map type whose type is MapType. This map type is only be available if this plugin parameter is set, in which case it is always Map::supportedMapTypes [supportedMapTypes. CustomMap via urlprefix parameter. This copyright will only be used when using the CustomMap from above.

If empty no map copyright will be displayed for the custom map. If empty no data copyright will be displayed for the custom map.

This is done to prevent using hardcoded servers by default, which may become unavailable. By default this information is fetched from maps-redirect. Setting this parameter changes the provider repository address to a user-specified one, which must contain the files streetsatellitecycletransitnight-transitterrain and hikingeach of which must contain valid provider information.

The plugin, however, still contains fallback hardcoded provider data, in case the provider repository becomes unreachable.

Setting this parameter to true makes the plugin use the hardcoded urls only and therefore prevents the plugin from fetching provider data from the remote repository. Valid values are true and false. The default value is false. Please note that not all map types are available in high dpi.Many software tools and services allow you to use OpenStreetMap data offlinewithout an Internet connection.

One challenge with offline editing is that a downloaded area can become out of date, so that by the time you make your edits and upload them, conflicts arise with intervening edits by other mappers. This problem is exacerbated in scenarios such as disaster relief, where many people need to contribute to the same part of the map in tandem while offline. Quickly serving huge volumes of raster or vector tile data can incur a significant cost to map providers.

Therefore, even free-of-cost services usually limit the number of tiles you can download, the rate at which you can download them, or the geographic area or level of detail that you can download. Otherwise, please respect the restrictions imposed by the tool or service you choose. From OpenStreetMap Wiki. Purge Help.
