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

Hi everyone,
I'm not sure this is the channel to send doubts to the
community....anyway, let's go! (If not, im sorry and please tell me
the correct way to do it.)
My question is how to include a download button for downloadind a
vector layer with lines/pol draw by user. explain:
I have a map developed with geoext with several functions.
With the drawing controls, user is able to draw polygon and lines and
stores it in a vector layer (called vector1). I need to give the
user the possibility to download that vector layer containing its own
draw, but I have no idea how to do it!
The idea is to create a json layer and browse to save it in local user
pc....
Some help or idea please?
Thanks a lot
My code is:
var vector = new OpenLayers.Layer.Vector("vector1");
map.addLayers([vector]);
var ctrl, toolbarItems = [], action, actions = {};
action = new GeoExt.Action({
text: "Dibuja polígono",
control: new OpenLayers.Control.DrawFeature(
vector, OpenLayers.Handler.Polygon
),
map: map,
// button options
toggleGroup: "draw",
allowDepress: true,
tooltip: "draw polygon",
// check item options
group: "draw"
});
actions["draw_poly"] = action;
toolbarItems.push(action);
Thank again!
