zooms in and out. I've been looking through the GeoExt examples, and I
can't find any of them that incorporates this functionality. They
simple show how to turn on/off single layers. Ideally, I'd like to
integrate a GeoExt zoomslider and toolbar (with pan, zoom, measure
distance).<br><br>Can someone share GeoExt code that does this?<br><br>Thank you.<br><br>Petrus<br><br><span id="signature"></span><br></div></div></div>
