TWebOSMaps polylines

The TWebOSMaps demonstration source contains the following two consecutive lines:

  WebOSMaps1.DeleteAllMapPolyline;
  WebOSMaps1.Polylines.Clear;

What exactly does the second line do that is different from the first?

There is no description for either of these methods in the documentation.

Hi,


The first line removes all polyline objects from the map and the second line removes all polyline items from the Poylines collection.
Thanks
