LineString
is a component for drawing an open, continuous sequence of lines on a Map
. To add new points to a LineString
in the designer, drag the midpoint of any segment away from the line to introduce a new vertex. Move a vertex by clicking and dragging the vertex to a new location. Clicking on a vertex will delete the vertex, unless only two remain.

void com.google.appinventor.components.runtime.LineString.updatePoints | ( | List< GeoPoint > | points | ) |
Updates the points of the LineString without refreshing the map. This is intended to be called to finalize a drag event when the visual representation is correct but the internal representation in the component is not. NB: This should not invalidate the map view.
