[Users] how to include a download button for downloadind a vector layer with lines/pol draw by user

[Alexandre Dubé]

Hi,

   If you mean "export the features as text" then you need to pick a 
format in which you want to export your data, for example GeoJSON, KML, 
etc.  Here's a live example doing it in KML :

http://dev.geoext.org/geoext/sandbox/redlining/ux/FeatureEditing/examples/ControlerOnlyExample.html

   Start by drawing a feature (any first 3 tools).  A popup will appear 
in which there's an export button at the bottom left of the bottom 
toolbar.  You could also use the one in the map toolbar. Here's the code 
that actualy does the KML writing :

   Feel free to use any portion of this widget.

HTH,

Alexandre
