QT_BEGIN_NAMESPACE QDeclarativeSearchSuggestionModel::QDeclarativeSearchSuggestionModel ( QObject * parent = nullptr)
explicit

\qmltype PlaceSearchSuggestionModel \instantiates QDeclarativeSearchSuggestionModel \inqmlmodule QtLocation

Since
QtLocation 5.5

Provides access to search term suggestions.

The PlaceSearchSuggestionModel can be used to provide search term suggestions as the user enters their search term. The properties of this model should match that of the \l PlaceSearchModel, which will be used to perform the actual search query, to ensure that the search suggestion results are relevant.

There are two ways of accessing the data provided by this model, either through the \l suggestions property or through views and delegates. The latter is the preferred method.

The \l offset and \l limit properties can be used to access paged suggestions. When the \l offset and \l limit properties are set the suggestions between \l offset and (\l offset + \l limit - 1) will be returned. Support for paging may vary from plugin to plugin.

The model returns data for the following roles:

\table \header

  • Role
  • Type
  • Description \row
  • suggestion
  • string
  • Suggested search term. \endtable

The following example shows how to use the PlaceSearchSuggestionModel to get suggested search terms from a partial search term. The \l searchArea is set to match what would be used to perform the actual place search with \l PlaceSearchModel.

\codeline

See also
PlaceSearchModel, {QPlaceManager}

\qmlproperty Plugin PlaceSearchSuggestionModel::plugin

This property holds the provider \l Plugin which will be used to perform the search.

\qmlproperty geoshape PlaceSearchSuggestionModel::searchArea

This property holds the search area. Search suggestion results returned by the model will be relevant to the given search area.

If this property is set to a \l {geocircle} its \l {geocircle}{radius} property may be left unset, in which case the \l Plugin will choose an appropriate radius for the search.

\qmlproperty int PlaceSearchSuggestionModel::offset

This property holds the index of the first item in the model.

See also
limit

\qmlproperty int PlaceSearchSuggestionModel::limit

This property holds the limit of the number of items that will be returned.

See also
offset

\qmlproperty enum PlaceSearchSuggestionModel::status

This property holds the status of the model. It can be one of:

\table \row

  • PlaceSearchSuggestionModel.Null
  • No search query has been executed. The model is empty. \row
  • PlaceSearchSuggestionModel.Ready
  • The search query has completed, and the results are available. \row
  • PlaceSearchSuggestionModel.Loading
  • A search query is currently being executed. \row
  • PlaceSearchSuggestionModel.Error
  • An error occurred when executing the previous search query. \endtable

\qmlmethod void PlaceSearchSuggestionModel::update()

Updates the model based on the provided query parameters. The model will be populated with a list of search suggestions for the partial \l searchTerm and \l searchArea. If the \l plugin supports it, other parameters such as \l limit and \l offset may be specified. update() submits the set of parameters to the \l plugin to process.

While the model is updating the \l status of the model is set to PlaceSearchSuggestionModel.Loading. If the model is successfully updated, the \l status is set to PlaceSearchSuggestionModel.Ready, while if it unsuccessfully completes, the \l status is set to PlaceSearchSuggestionModel.Error and the model cleared.

This example shows use of the model

PlaceSeachSuggestionModel {
plugin: backendPlugin
searchArea: QtPositioning.circle(QtPositioning.coordinate(10, 10))
...
}
MouseArea {
...
onClicked: {
model.searchTerm = "piz"
model.searchArea.center.latitude = -27.5;
model.searchArea.cetner.longitude = 153;
model.update();
}
}

A more detailed example can be found in the in \l {Places (QML)#Presenting-Search-Suggestions}{Places (QML)} example.

See also
cancel(), status

\qmlmethod void PlaceSearchSuggestionModel::cancel()

Cancels an ongoing search suggestion operation immediately and sets the model status to PlaceSearchSuggestionModel.Ready. The model retains any search suggestions it had before the operation was started.

If an operation is not ongoing, invoking cancel() has no effect.

See also
update(), status

\qmlmethod void PlaceSearchSuggestionModel::reset()

Resets the model. All search suggestions are cleared, any outstanding requests are aborted and possible errors are cleared. Model status will be set to PlaceSearchSuggestionModel.Null.

\qmlmethod string QtLocation::PlaceSearchSuggestionModel::errorString() const

This read-only property holds the textual presentation of the latest search suggestion model error. If no error has occurred, or if the model was cleared, an empty string is returned.

An empty string may also be returned if an error occurred which has no associated textual representation.
