Member Function Documentation

[explicit] MapGraphicsView::MapGraphicsView(QWidget *parent = nullptr)

Default constructor that takes an optional parent.

[explicit] MapGraphicsView::MapGraphicsView(Esri::ArcGISRuntime::Map *map, QWidget *parent = nullptr)

Constructor that takes a map and an optional parent.

[override virtual noexcept] MapGraphicsView::~MapGraphicsView()

Destructor.

[signal] void MapGraphicsView::analysisViewStateChanged(Esri::ArcGISRuntime::Analysis *analysis, const Esri::ArcGISRuntime::AnalysisViewState &analysisViewState)

Signal emitted when the AnalysisViewState changes.

• analysis - The analysis that had a state change.
• analysisViewState - The AnalysisViewState with the new state information.

The returned Analysis object has the MapGraphicsView as its parent.

[signal, since Esri::ArcGISRuntime 100.1] void MapGraphicsView::attributionRectChanged()

Emitted when the attribution bounding rectangle changes.

This function was introduced in Esri::ArcGISRuntime 100.1.

[signal, since Esri::ArcGISRuntime 100.1] void MapGraphicsView::attributionTextChanged()

Emitted when the attribution text changes.

This function was introduced in Esri::ArcGISRuntime 100.1.

[signal] void MapGraphicsView::drawStatusChanged(Esri::ArcGISRuntime::DrawStatus status)

Signal emitted when the DrawStatus changes.

• status - The new DrawStatus.

[signal] void MapGraphicsView::errorOccurred(const Esri::ArcGISRuntime::Error &error)

Signal emitted when an error occurs.

• error - Details about the error.

[signal, since Esri::ArcGISRuntime 300.0] void MapGraphicsView::geoModelErrorChanged(const Esri::ArcGISRuntime::Error &error)

Signal emitted when the geo model error changes.

This error is used to indicate that the geo model assigned to the view had an issue loading or didn't meet the requirements after loading, resulting in nothing rendering on screen.

This signal can be emitted multiple times but only one error can be active at a time. It will be emitted when there is an error and when that error gets cleared. When the error is cleared, then the error is represented as empty.

Examples of a possible error include:

• Geo model has a Loadable::loadError.
• Incompatible Scene::viewingMode.
• Geo model has an incompatible spatial reference.
• Geo model has incompatible vertical and horizontal datums.

• error - The geo model error associated with the view.

This function was introduced in Esri::ArcGISRuntime 300.0.

• hoverEvent - The hover event.

This function was introduced in Esri::ArcGISRuntime 200.2.

[signal, since Esri::ArcGISRuntime 200.2] void MapGraphicsView::hoverLeft(QHoverEvent &hoverEvent)

Emitted when the cursor leaves.

• hoverEvent - The hover event.

This function was introduced in Esri::ArcGISRuntime 200.2.

[signal, since Esri::ArcGISRuntime 200.2] void MapGraphicsView::hoverMoved(QHoverEvent &hoverEvent)

Emitted when the cursor moves.

• hoverEvent - The hover event.

This function was introduced in Esri::ArcGISRuntime 200.2.

[signal] void MapGraphicsView::keyPressed(QKeyEvent &keyEvent)

Emitted when a key press has been detected.

• keyEvent - The key event.

[signal] void MapGraphicsView::keyReleased(QKeyEvent &keyEvent)

Emitted when a key release has been detected.

• keyEvent - The key event.

[signal] void MapGraphicsView::layerViewStateChanged(Esri::ArcGISRuntime::Layer *layer, const Esri::ArcGISRuntime::LayerViewState &layerViewState)

Signal emitted when the LayerViewState changes.

• layer - The layer that had a state change.
• layerViewState - The LayerViewState with the new state information.

The returned Layer object has the MapGraphicsView as its parent.
