    Detailed Description

    This object allows you to know the current state of a layer in a view.

    Member Function Documentation


    The default constructor.

    LayerViewState::LayerViewState(const Esri::ArcGISRuntime::LayerViewState &other)

    The copy constructor from other LayerViewState.

    LayerViewState::LayerViewState(Esri::ArcGISRuntime::LayerViewState &&other)

    Move operator from other LayerViewState.


    The destructor.

    Esri::ArcGISRuntime::Error LayerViewState::error() const

    Gets the error that describes a problem encountered when displaying layers in a GeoView.

    For your application, an error may be critical for the user's interaction with the view's data content. Depending on the type of problem encountered, you could:

    • Call retryLoad()
    • Remove the layer from the Map or Scene
    • Inspect the data
    • Check your network connection
    • Check whether an online service is experiencing problems

    See also Loadable.

    [since Esri::ArcGISRuntime 100.1] Esri::ArcGISRuntime::LayerViewStatusFlags LayerViewState::statusFlags() const

    Returns the combination of LayerViewStatus enum to describe the current layer view state.

    A valid layer state is a bitwise OR combination of the LayerViewStatus enum values.

    if (viewState.statusFlags() & Esri::ArcGISRuntime::LayerViewStatus::Active)
      return "Active";
    else if (viewState.statusFlags() & Esri::ArcGISRuntime::LayerViewStatus::NotVisible)
      return "Not Visible";
    else if (viewState.statusFlags() & Esri::ArcGISRuntime::LayerViewStatus::OutOfScale)
      return "Out of Scale";
    else if (viewState.statusFlags() & Esri::ArcGISRuntime::LayerViewStatus::Loading)
      return "Loading";
    else if (viewState.statusFlags() & Esri::ArcGISRuntime::LayerViewStatus::Error)
      return "Error";
      return "Unknown";

    Note: The return value makes use of the QFlags class. Please see the Qt documentation for more details on usage.

    This function was introduced in Esri::ArcGISRuntime 100.1.

    See also LayerViewStatus.

    Esri::ArcGISRuntime::LayerViewState &LayerViewState::operator=(const Esri::ArcGISRuntime::LayerViewState &other)

    The assignment operator from other LayerViewState.

    Esri::ArcGISRuntime::LayerViewState &LayerViewState::operator=(Esri::ArcGISRuntime::LayerViewState &&other)

    The move operator from other LayerViewState.
