Show features both in a grid and on the map and have them selectable.
Sample code showing how to configure a Heron FeaturePanel. In this case a popup ExtJS Window is created with a single FeaturePanel (xtype: ‘hr_featurepanel’).
Ext.onReady(function () {
// create a panel and add the map panel and grid panel
// inside it
new Ext.Window({
title: __('Click Map or Grid to Select - Double Click to Zoom to feature'),
layout: "fit",
x: 50,
y: 100,
height: 400,
width: 280,
items: [{
xtype: 'hr_featurepanel',
id: 'hr-featurepanel',
title: __('Parcels'),
header: false,
columns: [
{
header: "Fid",
width: 60,
dataIndex: "id",
type: 'string'
},
{
header: "ObjectNum",
width: 180,
dataIndex: "objectnumm",
type: 'string'
}
],
hropts: {
storeOpts: {
proxy: new GeoExt.data.ProtocolProxy({
protocol: new OpenLayers.Protocol.HTTP({
url: 'data/parcels.json',
format: new OpenLayers.Format.GeoJSON()
})
}),
autoLoad: true
},
zoomOnRowDoubleClick: true,
zoomOnFeatureSelect: false,
zoomLevelPointSelect: 8,
separateSelectionLayer: true
}
}
]
}).show();
});
Configuration properties in addition to those listed for GeoExt.form.FormPanel.
Boolean Should the store and grid columns autoconfigure from loaded features?.
Integer Maximum number of features to ‘sniff’ for autoconfigured grid columns (as null columns are often not sent by server).
Integer The maximum width of a auto adjusted column grid response. Setting to 0 will disable auto column width detection
Boolean Should the column names be capitalized when autoconfig is true?
Integer The width of a column in a grid response
String Array
tring array of types of Panels to display GFI info in, default value is [‘Table’], a grid table. ther value is ‘Detail’, a propertyPanel showing records one by one in a “Vertical” view. f multiple display values are given buttons in the toolbar will be shown to switch display types. irst value is the panel to be opened at the first time info is requested nly more than one displayPanel will be available when showTopToolbar = true. ote: The old implementation with ‘Tree’ and ‘XML’ was deprecated from v0.75
Boolean Should the features in the panel be downloadble? Download can be effected in 3 ways: 1. via Grid export (CSV and XLS only) 2. downloading the original feature format (GML2) 3. (GeoServer only) requesting the server for a triggered download (all Geoserver WFS formats)
Object The supported configs for formatting and exporting feature data. Actual presented download options are configured with exportFormats.
String Array
rray of document formats to be used when exporting the content of the FeaturePanel. This requires the server-side CGI script heron.cgi` to be installed. Exporting results in a download of a document with the content of the FeaturePanel. or example when ‘XLS’ is configured, exporting will result in the Excel (or compatible) program to be tarted with the data in an Excel worksheet. tandard option values are CSV, XLS, GMLv2, GeoJSON, Shapefile, WellKnownText, default is, null, eaning no export (results in no export menu). These configured values select a formatter-object from he exportConfigs map. ince v0.77 it is also possible to supply your own formatter-objects within this array. For example for dditional OGR-formats and/or -projections. Here is an example of a Shapefile in Dutch projection:
['GMLv2', 'GeoJSON',{
name: 'Esri Shapefile (WGS84)',
formatter: 'OpenLayersFormatter',
format: 'OpenLayers.Format.GeoJSON',
targetFormat: 'ESRI Shapefile',
targetSrs: 'EPSG:4326',
fileExt: '.zip',
mimeType: 'application/zip'
}, 'WellKnownText']
Boolean Should the feature geometries that are shown be selectable in grid and map? Default true.
Array An array of column names from WFS and WMS GetFeatureInfo results that should be removed and not shown to the user.
Boolean Should selected features be managed in separate overlay Layer (handy for printing) ?.
Boolean Should the feature geometries be shown? Default true.
Boolean Should a top toolbar with feature count, clear button and download combo be shown? Default true.
Object Options to be passed on Vector constructors.
Integer Zoom level when layer is single point feature, default 10.
Integer Zoom level for point features when selected, default 10.
Boolean Zoom to feature (extent) when selected ?.
Boolean Zoom to feature (extent) when row is double clicked ?.
Boolean Zoom to layer data extent when loaded ?.
