| 49 | |
| 50 | \brief The Plugin type describes a Location based services plugin. |
| 51 | |
| 52 | The Plugin type is used to declaratively specify which available |
| 53 | GeoServices plugin should be used for various tasks in the Location API. |
| 54 | Plugins are used by \l Map, \l RouteModel, and \l GeocodeModel |
| 55 | types, as well as a variety of others. |
| 56 | |
| 57 | Plugins recognized by the system have a \l name property, a simple string |
| 58 | normally indicating the name of the service that the Plugin retrieves |
| 59 | data from. They also have a variety of features, which can be test for using the |
| 60 | \l {supportsRouting()}, \l {supportsGeocoding()}, \l {supportsMapping()}, |
| 61 | \l {supportsPlaces()} and \l {supportsNavigation()} methods. |
| 62 | |
| 63 | When a Plugin object is created, it is "detached" and not associated with |
| 64 | any actual service plugin. Once it has received information via setting |
| 65 | its \l name, \l preferred, or \l required properties, it will choose an |
| 66 | appropriate service plugin to attach to. Plugin objects can only be |
| 67 | attached once; to use multiple plugins, create multiple Plugin objects. |
| 68 | |
| 69 | \section2 Example Usage |
| 70 | |
| 71 | The following snippet shows a Plugin object being created with the |
| 72 | \l required and \l preferred properties set. This Plugin will attach to the |
| 73 | first found plugin that supports both mapping and geocoding, and will |
| 74 | prefer plugins named "here" or "osm" to any others. |
| 75 | |
| 76 | \code |
| 77 | Plugin { |
| 78 | id: plugin |
| 79 | preferred: ["here", "osm"] |
| 80 | required: Plugin.AnyMappingFeatures | Plugin.AnyGeocodingFeatures |
| 81 | } |
| 82 | \endcode |

| 551 | |
| 552 | This property contains an ordered list of preferred plugin locales. If the first locale cannot be accommodated, then |
| 553 | the backend falls back to using the second, and so on. By default the locales property contains the system locale. |
| 554 | |
| 555 | The locales are specified as strings which have the format |
| 556 | "language[_script][_country]" or "C", where: |
| 557 | |
| 558 | \list |
| 559 | \li language is a lowercase, two-letter, ISO 639 language code, |
| 560 | \li script is a titlecase, four-letter, ISO 15924 script code, |
| 561 | \li country is an uppercase, two- or three-letter, ISO 3166 country code (also "419" as defined by United Nations), |
| 562 | \li the "C" locale is identical in behavior to English/UnitedStates as per QLocale |
| 563 | \endlist |
| 564 | |
| 565 | If the first specified locale cannot be accommodated, the \l {Plugin} falls back to the next and so forth. |
| 566 | Some \l {Plugin} backends may not support a set of locales which are rigidly defined. An arbitrary |
| 567 | example is that some \l {Place}'s in France could have French and English localizations, while |
| 568 | certain areas in America may only have the English localization available. In the above scenario, |
| 569 | the set of supported locales is context dependent on the search location. |
| 570 | |
| 571 | If the \l {Plugin} cannot accommodate any of the preferred locales, the manager falls |
| 572 | back to using a supported language that is backend specific. |
| 573 | |
| 574 | For \l {Plugin}'s that do not support locales, the locales list is always empty. |

| 873 | |
| 874 | \brief The PluginParameter type describes a parameter for a plugin, either |
| 875 | geo service \l Plugin, or \l{Qt Positioning plugins}{position Plugin}. |
| 876 | |
| 877 | The PluginParameter object is used to provide a parameter of some kind |
| 878 | to a plugin. Typically these parameters contain details like an application |
| 879 | token for access to a service, or a proxy server to use for network access, |
| 880 | or the serial port to which a serial GPS receiver is connected. |
| 881 | |
| 882 | To set such a parameter, declare a PluginParameter inside an element that accepts |
| 883 | plugin parameters as configuration objects, such as a \l Plugin object, or a |
| 884 | \l PositionSource object, and give it \l{name} and \l{value} properties. A list of valid |
| 885 | parameter names for each plugin is available from the |
| 886 | \l {Qt Location#Plugin References and Parameters}{plugin reference pages} for geoservice plugins, |
| 887 | and \l {Qt Positioning plugins#Default plugins} for position plugins. |
| 888 | |
| 889 | \section2 Example Usage |
| 890 | |
| 891 | The following example shows an instantiation of the \l {Qt Location HERE Plugin}{HERE} plugin |
| 892 | with a mapping API \e app_id and \e token pair specific to the application. |
| 893 | |
| 894 | \code |
| 895 | Plugin { |
| 896 | name: "here" |
| 897 | PluginParameter { name: "here.app_id"; value: "EXAMPLE_API_ID" } |
| 898 | PluginParameter { name: "here.token"; value: "EXAMPLE_TOKEN_123" } |
