Events

The map has several events. You can trigger actions to happen when these events occur.

On Map Ready

This event happens when the Map has loaded in your app.

This is a good time to add any markers, polylines or polygons to your app that you want the user to see as soon as your app opens.

On User Location Change

This event happens when the location of the user changes. It returns the coordinate object. You can use object blocks to get the properties of the coordinate object.

The coordinate object has the following properties:

{ target: Numeric ID for your app coordinate:{ latitude: latitude of point selected longitude: longitude of point selected } position:{ x: x-position of selected point on the Map component y: x-position of selected point on the Map component } }

On Press

This event happens when the user taps on the Map.

On Long Press

This event happens when the user presses on the map for a longer period of time.

On Marker Press

This event happens when the user clicks on a Marker that is on the Map.

The On Marker Press block returns an event object. This is an object which can be used with object blocks.

The event object has the following properties:

{ latitude: latitude of the selected Marker longitude: longitude of the selected Marker }
