In this particular case, a search + for places associated with the term \c pizza is performed. + + \section1 Performing a Place Search + + To write a QML application that will show places in a list, we start by + making the following import declarations. + + \snippet places_list/places_list.qml Imports + + Instantiate a \l Plugin instance. The \l Plugin is effectively the backend + from where places are sourced from. Depending on the type of the plugin, + some mandatory parameters may be need to be filled in. The most likely type + of PluginParameter are some form of service access token which are documented + in the service plugin. As an example see the \l + {Mandatory Parameters} {HERE Plugin} documentation. In this snippet the \c osm + plugin is used which does not require any further parameter: + + \snippet places_list/places_list.qml Initialize Plugin + + Next we instantiate a \l PlaceSearchModel which we can use to specify + search parameters and perform a places search operation. For illustrative + purposes, \l {PlaceSearchModel::update} {update()} is invoked once + construction of the model is complete. Typically \l + {PlaceSearchModel::update} {update()} would be invoked in response to a + user action such as a button click. + + \snippet places_list/places_list.qml PlaceSearchModel + + Finally we instantiate a \l ListView to show the search results found by + the model. An inline delegate has been used and we have assumed that + every search result is of \l {Search Result Types} {type} \c + PlaceSearchesult. Consequently it is assumed that we always have access to + the \e place \l {PlaceSearchModel Roles} {role}, other search result types + may not have a \e place \l {PlaceSearchModel Roles} {role}. + + \snippet places_list/places_list.qml Places ListView +*/ |
