| 93 | <p>Welcome to GeoExt! This document is intended to help you get started |
---|
| 94 | with GeoExt. With GeoExt, you can start from nothing and have a rich |
---|
| 95 | mapping application in seconds.</p> |
---|
| 96 | <div class="section" id="getting-geoext"> |
---|
| 97 | <h2>Getting GeoExt<a class="headerlink" href="#getting-geoext" title="Permalink to this headline">¶</a></h2> |
---|
| 98 | <p>GeoExt is built on top of the robust OpenLayers JavaScript mapping |
---|
| 99 | library and the rich graphical components of ExtJS. For licensing |
---|
| 100 | reasons, ExtJS cannot be included in the GeoExt download, so preparing |
---|
| 101 | GeoExt for use on your own web pages is a multi-step process:</p> |
---|
| 102 | <ol class="arabic simple"> |
---|
| 103 | <li>Download GeoExt from the <a class="reference external" href="../downloads.html"><em>downloads page</em></a>. For the purposes |
---|
| 104 | of this quickstart, the development version will be fine.</li> |
---|
| 105 | <li>Download OpenLayers 2.10 or later from <a class="reference external" href="http://openlayers.org/">http://openlayers.org/</a>.</li> |
---|
| 106 | <li>Download ExtJS 3.2 from <a class="reference external" href="http://www.sencha.com/products/js/download.php">the ExtJS website</a>.</li> |
---|
| 107 | <li>Place both unpacked libraries in a directory that is published by your web |
---|
| 108 | server. For this tutorial, I will assume that this is the root of your web |
---|
| 109 | server, so that GeoExt.js is at <a class="reference external" href="http://localhost/GeoExt/lib/GeoExt.js">http://localhost/GeoExt/lib/GeoExt.js</a> and |
---|
| 110 | ext-all.js is at <a class="reference external" href="http://localhost/ext-3.2.1/ext-all.js">http://localhost/ext-3.2.1/ext-all.js</a></li> |
---|
| 111 | <li>Now you’re ready to use GeoExt in your application!</li> |
---|
| 112 | </ol> |
---|
| 113 | <div class="admonition note"> |
---|
| 114 | <p class="first admonition-title">Note</p> |
---|
| 115 | <p class="last">For production environments, the GeoExt team recommends that |
---|
| 116 | you use compressed and minified builds of GeoExt and ExtJS to |
---|
| 117 | optimize the download size of your page. A generic minified build |
---|
| 118 | containing all of GeoExt is available from the |
---|
| 119 | <a class="reference external" href="../downloads.html"><em>downloads page</em></a>, but advanced users can build their |

| 120 | own.</p> |
