FeatureGrid
(config)¶ Plugin for displaying vector features in a grid. Requires a
gxp.plugins.FeatureManager
. Also provides a context menu for the grid.
Config Options¶
Configuration properties in addition to those listed for Ext.util.Observable.
-
actions
Array
Custom actions for tools that do not provide their own. Array elements are expected to be valid Ext config objects or strings referencing a valid Ext component. Actions provided here may have additionalmenuText
andbuttonText
properties. The former will be used as text when the action is used in a menu. The latter will be conditionally used on buttons, only ifshowButtonText
is set to true. The nativetext
property will unconditionally be used for buttons. Optional, only needed to create custom actions.
-
actionTarget
Object
orString
orArray
Where to place the tool’s actions (e.g. buttons or menus)?In case of a string, this can be any string that references an
Ext.Container
property on the portal, or a unique id configured on a component.In case of an object, the object has a “target” and an “index” property, so that the tool can be inserted at a specified index in the target.
actionTarget can also be an array of strings or objects, if the action is to be put in more than one place (e.g. a button and a context menu item).
To reference one of the toolbars of an
Ext.Panel
, ”.tbar”, ”.bbar” or ”.fbar” has to be appended. The default is “map.tbar”. The viewer’s main MapPanel can always be accessed with “map” as actionTarget. Set to null if no actions should be created.Some tools provide a context menu. To reference this context menu as actionTarget for other tools, configure an id in the tool’s outputConfig, and use the id with ”.contextMenu” appended. In the snippet below, a layer tree is created, with a “Remove layer” action as button on the tree’s top toolbar, and as menu item in its context menu:
{ xtype: "gxp_layertree", outputConfig: { id: "tree", tbar: [] } }, { xtype: "gxp_removelayer", actionTarget: ["tree.tbar", "tree.contextMenu"] }
If a tool has both actions and output, and you want to force it to immediately output to a container, set actionTarget to null. If you want to hide the actions, set actionTarget to false. In this case, you should configure a defaultAction to make sure that an action is active.
-
alwaysDisplayOnMap
Boolean
If set to true, the features that are shown in the grid will always be displayed on the map, and there will be no “Display on map” button in the toolbar. Default is false. If set to true, no “Display on map” button will be shown.

If set to true, and when this tool’s output is added to a container that can be expanded, it will be expanded when features are loaded. Default is false.
-
autoLoadFeature
Boolean
Should this tool load a feature on click? If set to true, and if there is no loaded feature at the click position, this tool will call loadFeatures on thefeatureManager
, with aFeatureId
filter created from the id of a feature returned from a WMS GetFeatureInfo request at the click position. This feature will then be selected immediately. Default is false.
-
controlOptions
Object
Options for theOpenLayers.Control.SelectFeature
used with this tool.
-
defaultAction

Optional configuration for the output container. This may be useful to override the xtype (e.g. “window” instead of “gx_popup”), or to provide layout configurations when rendering to anoutputTarget
.
-
outputTarget
String
Where to add the tool’s output container? This can be any string that references anExt.Container
property on the portal, or “map” to access the viewer’s main map. If not provided, a window will be created. To reference one of the toolbars of anExt.Panel
, ”.tbar”, ”.bbar” or ”.fbar” has to be appended.
