Add a point, line, and polygon

Learn how to display point, line, and polygon graphics in a map.

You typically use graphics to display geographic data that is not connected to a database and that is not persisted, like highlighting a route between two locations, displaying a search buffer around a point, or tracking the location of a vehicle in real-time. Graphics are composed of a geometry, symbol, and attributes.

In this tutorial, you display points, lines, and polygons on a map as graphics.

To learn how to display data from data sources, see the Add a feature layer tutorial.

Prerequisites

Steps

Open the project in Qt Creator

1. To start this tutorial, complete the Display a map tutorial or download and unzip the solution.

2. Open the display_a_map project in Qt Creator.

3. If you downloaded the Display a map solution, set your API key.

   More info

   An API Key enables access to services, web maps, and web scenes hosted in ArcGIS Online.

   1. Go to your developer dashboard to get your API key. For these tutorials, use your default API key. It is scoped to include all of the services demonstrated in the tutorials.

   2. In the Projects window, in the Sources folder, open the main.cpp file.

   3. Modify the code to set the API key. Paste the API key, acquired from your dashboard, between the quotes.

      main.cpp

Add GraphicsOverlay class, declare member function

GraphicsOverlay is a container for temporary graphics to display on your map view. The graphics drawn in graphics overlays are created at runtime and are not persisted when your application closes. Learn more about GraphicsOverlay.

1. In the display_a_map project, double click Headers > Display_a_map.h to open the file. Add the GraphicsOverlay class to the namespace ArcGISRuntime declaration.

Create a graphics overlay

A graphics overlay is a container for graphics. It is added to a map view to display graphics on a map. You can add more than one graphics overlay to a map view. Graphics overlays are displayed on top of all the other layers.

Add a point graphic

A point graphic is created using a point and a marker symbol. A point is defined with x and y coordinates for longitude and latitude coordinates, and a spatial reference. The spatial reference is WGS84.

1. Create a Point and a SimpleMarkerSymbol. To create the Point, provide longitude (x) and latitude (y) coordinates, and a SpatialReference.

   More info

   Point graphics support a number of symbol types such as SimpleMarkerSymbol, PictureMarkerSymbol and TextSymbol. See Symbol in the API documentation to learn more about symbols.

Add a polyline graphic

A line graphic is created using a polyline and a line symbol. A polyline is defined as a sequence of points.

1. Create a Polyline and a SimpleLineSymbol.

   To create the Polyline, create a new PointCollection with a SpatialReference and use PolylineBuider to add a new Points to it. Add the highlighted code.
