  • TimeSliderController
  • In MVC architecture, this is the controller for the corresponding TimeSlider. More...

    Since: Esri.ArcGISRuntime 100.10




    Detailed Description

    This controller calculates interval steps and the range of the full extent for the TimeSlider. This is based on the combined extents of time-aware layers in the given GeoView.

    The time-extent of the GeoView itself can be manipulated using steps with calls to setSteps.

    Here is an example of how to use the TimeSlider from QML.

    import "qrc:///Esri/ArcGISRuntime/Toolkit" as Toolkit
    // add a mapView component (the geoView)
    MapView {
        anchors.fill: parent
        id: mapView
        Map {
        // declare a TimeSlider and bind it to the geoView
        Toolkit.TimeSlider {
            id: timeSlider
            anchors {
                left: mapView.left
                right: mapView.right
                bottom: mapView.attributionTop
            geoView: mapView

    Property Documentation

    [read-only] endStep : alias

    The current end step.

    geoView : alias

    The GeoView object this Controller uses.

    [read-only] numberOfSteps : alias

    The number of steps the TimeSlider should display based on on the fullTimeExtent dividied by smallest timeInterval.

    [read-only] startStep : alias

    The current start step.

    Signal Documentation


    Emitted when the extents of any TimeAware layer changes.

    Note: The corresponding handler is onExtentsChanged.


    Emitted when either the start or end step changes.

    Note: The corresponding handler is onStepsChanged.

    Method Documentation

    setSteps(startStep, endStep)

    Sets the current steps.

    Setting steps changes the the current time-extent of the GeoView to a TimeExtent range calculated by the current steps using timeForStep.

    • startStep start-step to set.
    • endStep end-step to set.


    Calculates a date from a step.

    Given "step" and numberOfSteps, we can calculate the date-time for an arbitrary step interpolated between the start and end times of the full time extent.

    • step Step to calculate a time for.

    Returns a date that is the time calculated for the step.
