GeoExt 2

JavaScript Toolkit for Rich Web Mapping Applications.


What is GeoExt?

GeoExt is Open Source and enables building desktop-like GIS applications through
the web. It is a JavaScript framework that combines the GIS functionality of
OpenLayers with the user interface savvy of the
ExtJS library provided by
Sencha.

Version 2 of GeoExt is the successor to the
GeoExt 1.x-series.

GeoExt 2.1.x is built atop OpenLayers 2.13.1 and ExtJS 5.1.0 and provides full backward compatibility to ExtJS 4.2.1.
So GeoExt 2.1 is usable either with ExtJS 5.1 or Ext 4.2.1.

GeoExt 2.0.x is based on OpenLayers 2.13.1 and ExtJS 4.2.1 and is maintained in the v2.0.x-maintenance Branch.

More information on GeoExt 2

Have a look at the official homepage: http://geoext.github.io/geoext2/

You will find examples, API documentation (with and without inherited
functionality from ExtJS), links to mailinglists and more over there.

What you see on http://geoext.github.io/geoext2/ are the contents of the
gh-pages-branch. If you encounter anything that should be fixed, please issue
a pull request against that branch and we will merge it as soon as possible.

Ok, I want to use GeoExt now...

Hey that's a good decision, and it is very easy to get started on a page that
already includes ExtJS and OpenLayers:

``html





href="http://cdn.sencha.com/ext/gpl/5.1.0/build/packages/ext-theme-neptune/build/resources/ext-theme-neptune-all-debug.css">







`
Or if you are stuck to ExtJS 4.2.x you can use the following code:
`html





href="http://cdn.sencha.com/ext/gpl/4.2.1/resources/css/ext-all.css">







`

Next, we simply add a
`
Or reference the ExtJS 4.2.1 sources if you have to use them:
`html

`

That's it. Now you can e.g. create a very basic mappanel and let it reign over
the whole browser window:

`javascript
var mappanel = Ext.create('GeoExt.panel.Map', {
title: 'A sample Map',
map: {
// ...
// optional, can be either
// - a valid OpenLayers.Map configuration or
// - an instance of OpenLayers.Map
},
center: '12.31,51.48',
zoom: 6
});

Ext.create('Ext.container.Viewport', {
layout: 'fit',
items: [
mappanel // our variable from above
]
});
`

More information to get started can be grabbed
on the main website.

To generate the jsduck documentation

* Install jsduck: https://github.com/senchalabs/jsduck
* Run jsduck --config jsduck.json in the root of the repository
* Optional: If you want the documentation for ExtJS to be linked, edit
jsduck.json to point to the proper source location (URLs will not work)
* Optional: To refresh screenshots in the example page run
~$ . tools/screenshots.sh http://geoext.github.io/geoext2/examples/
* Open the generated file /path/to/your/geoext/docs/index.html in your
favorite browser
* Enjoy!




To run the test suite

* Serve the contents of a GeoExt 2 clone on a webserver, e.g.:

user@machine:/src/geoext2 $ python -m SimpleHTTPServer 2222

* Open the main test suite HTML file in a browser:

http://localhost:2222/tests/run-tests.html

* Click the button "run all"

Headless tests with casperjs

You can also run the above tests headlessly through casperjs.

`bash


Install dependencies via npm in the GeoExt 2 clone dir (only first time)

npm install

Run the suite in the root of the repository

npm test
``

These tests are also run though travis.
