Bienvenue sur PostGIS.fr

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.

96<p>A plugin to create tree node UIs that can have an Ext.Component below the
97node&#8217;s title. Can be plugged into any <tt class="docutils literal"><span class="pre">Ext.tree.TreePanel</span></tt> and will be
98applied to nodes that are extended with the
99<tt class="xref docutils literal"><span class="pre">GeoExt.Tree.TreeNodeUIEventMixin</span></tt>.</p>
100<p>If a node is configured with a <tt class="docutils literal"><span class="pre">component</span></tt> attribute, it will be rendered
101with the component in addition to icon and title.</p>
