Bienvenue sur PostGIS.fr , le site de la communauté des utilisateurs francophones de PostGIS.

PostGIS ajoute le support d'objets géographique à la base de données PostgreSQL. En effet, PostGIS "spatialise" le serverur PostgreSQL, ce qui permet de l'utiliser comme une base de données SIG.

Maintenu à jour, en fonction de nos disponibilités et des diverses sorties des outils que nous testons, nous vous proposons l'ensemble de nos travaux publiés en langue française.

8 * @class Ext.Panel
9 * @extends Ext.Container
10 * <p>Panel is a container that has specific functionality and structural components that make
11 * it the perfect building block for application-oriented user interfaces.</p>
12 * <p>Panels are, by virtue of their inheritance from {@link Ext.Container}, capable
13 * of being configured with a {@link Ext.Container#layout layout}, and containing child Components.</p>
14 * <p>When either specifying child {@link Ext.Component#items items} of a Panel, or dynamically {@link Ext.Container#add adding} Components
15 * to a Panel, remember to consider how you wish the Panel to arrange those child elements, and whether
16 * those child elements need to be sized using one of Ext's built-in <code><b>{@link Ext.Container#layout layout}</b></code> schemes. By
17 * default, Panels use the {@link Ext.layout.ContainerLayout ContainerLayout} scheme. This simply renders
18 * child components, appending them one after the other inside the Container, and <b>does not apply any sizing</b>
19 * at all.</p>
20 * <p>A Panel may also contain {@link #bbar bottom} and {@link #tbar top} toolbars, along with separate
21 * {@link #header}, {@link #footer} and {@link #body} sections (see {@link #frame} for additional
22 * information).</p>
23 * <p>Panel also provides built-in {@link #collapsible expandable and collapsible behavior}, along with
24 * a variety of {@link #tools prebuilt tool buttons} that can be wired up to provide other customized
25 * behavior.  Panels can be easily dropped into any {@link Ext.Container Container} or layout, and the
26 * layout and rendering pipeline is {@link Ext.Container#add completely managed by the framework}.</p>
