Detailed Description

Modifying this collection (adding, removing, moving) will update the graphics overlays available in the GeoView.

The model returns data for the following roles:

minScaledoubleThe minimum scale at which the graphics should be displayed.GraphicsOverlayMinScaleRole
maxScaledoubleThe maximum scale at which the graphics should be displayed.GraphicsOverlayMaxScaleRole
graphicsOverlayOpacityfloatThe opacity of the graphics.GraphicsOverlayOpacityRole
graphicsOverlayVisibleboolWhether the graphics overlay is visible.GraphicsOverlayVisibleRole
selectionColorQColorThe selection color applied to selected graphics.GraphicsOverlaySelectionColorRole
idQStringThe ID of the selected graphics.GraphicsOverlayIdRole

void GraphicsOverlayListModel::append(Esri::ArcGISRuntime::GraphicsOverlay *graphicsOverlay)

Appends the graphicsOverlay to the graphics overlay list model.

[override virtual] Esri::ArcGISRuntime::GraphicsOverlay *GraphicsOverlayListModel::at(int index) const

Returns the graphics overlay at the specified index.

void GraphicsOverlayListModel::clear()

Removes all graphics overlays from the list model.

bool GraphicsOverlayListModel::contains(Esri::ArcGISRuntime::GraphicsOverlay *graphicsOverlay) const

Returns true if the provided graphicsOverlay is in the list model.

[override virtual] QVariant GraphicsOverlayListModel::data(const QModelIndex &index, int role = Qt::DisplayRole) const

Reimplements: QAbstractItemModel::data(const QModelIndex &index, int role) const.

Returns the data stored under the given role for the graphics overlay referred to by the index.

  • index. The index in the model for which to return data.
  • role. The role for which to return data.

Esri::ArcGISRuntime::GraphicsOverlay *GraphicsOverlayListModel::first() const

Returns the first graphics overlay in the list model.

int GraphicsOverlayListModel::indexOf(Esri::ArcGISRuntime::GraphicsOverlay *graphicsOverlay) const

Returns the index of the provided graphicsOverlay in the list model.

void GraphicsOverlayListModel::insert(int index, Esri::ArcGISRuntime::GraphicsOverlay *graphicsOverlay)

Inserts a graphicsOverlay at a specified index in the list model.

bool GraphicsOverlayListModel::isEmpty() const

Returns true if this list model is empty.

Esri::ArcGISRuntime::GraphicsOverlay *GraphicsOverlayListModel::last() const

Returns the last graphics overlay in the list model.

void GraphicsOverlayListModel::move(int from, int to)

Moves one graphics overlay from an index in the list model to a different index.

void GraphicsOverlayListModel::removeAt(int index)

Removes a graphics overlay at the specified index in the list model.

void GraphicsOverlayListModel::removeOne(Esri::ArcGISRuntime::GraphicsOverlay *graphicsOverlay)

Removes the specified graphicsOverlay from the list model.

[override virtual] int GraphicsOverlayListModel::size() const

Returns the number of graphics overlays in the model.
