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.

20.. class:: FeatureSelectionModel
21
22    A row selection model which enables automatic selection of features
23    in the map when rows are selected in the grid and vice-versa.

27Example Use
28-----------
29
30Sample code to create a feature grid with a feature selection model:
31
32.. code-block:: javascript
33
34     var gridPanel = new Ext.grid.GridPanel({
35        title: "Feature Grid",
36        region: "east",
37        store: store,
38        width: 320,
39        columns: [{
40            header: "Name",
41            width: 200,
42            dataIndex: "name"
43        }, {
44            header: "Elevation",
45            width: 100,
46            dataIndex: "elevation"
47        }],
48        sm: new GeoExt.grid.FeatureSelectionModel()
49    });

54Config Options
55--------------
56
57Configuration properties in addition to
58those listed for `Ext.grid.RowSelectionModel <http://dev.sencha.com/deploy/dev/docs/?class=Ext.grid.RowSelectionModel>`_.
59
60
61.. describe:: autoActivateControl
62
63    ``Boolean`` If true the select feature control is activated and
64    deactivated when binding and unbinding. Defaults to true.
65
66.. describe:: layer
67
68    ``OpenLayers.Layer.Vector`` The vector layer used for the creation of
69    the select feature control, it must already be added to the map. If not
70    provided, the layer bound to the grid's store, if any, will be used.
71
72.. describe:: layerFromStore
73
74    ``Boolean`` If true, and if the constructor is passed neither a
75    layer nor a select feature control, a select feature control is
76    created using the layer found in the grid's store. Set it to
77    false if you want to manually bind the selection model to a
78    layer. Defaults to true.
79
80.. describe:: selectControl
81
82    ``OpenLayers.Control.SelectFeature`` A select feature control. If not
83    provided one will be created.  If provided any "layer" config option
84    will be ignored, and its "multiple" option will be used to configure
85    the selectionModel.  If an ``Object`` is provided here, it will be
86    passed as config to the SelectFeature constructor, and the "layer"
87    config option will be used for the layer.

106        control.
107    :param options: ``Object`` An object with a "controlConfig"
108        property referencing the configuration object to pass to the
