class Heron.widgets.FeatureInfoPopup(config)

A Popup to hold the Panel designed to hold WMS GetFeatureInfo (GFI) data for one or more WMS layers.

Example Use

This class can be configured via the Toolbar. It is usually not created explicitly. It can be either a regular ‘featureinfo’ or ‘tooltips’ widget button. A FeatureInfoPopup can be triggered by clcking or hovering, dependent on the config, both shown below. Below two sample configs for the toolbar.

{type: "featureinfo", options: {
       pressed: true,
       getfeatureControl: {
           hover: true,
           drillDown: false,
           maxFeatures: 1
       },
       popupWindow: {
           width: 320,
           height: 200,
           anchored: false,
           featureInfoPanel: {
               // Option values are 'Grid', 'Tree' and 'XML', default is 'Grid' (results in no display menu)
               displayPanels: ['Grid'],
               // Export to download file. Option values are 'CSV', 'XLS', default is no export (results in no export menu).
               exportFormats: [],
               // exportFormats: ['CSV', 'XLS'],
               maxFeatures: 1
           }
       }
   }},

{type: "tooltips", options: {
       // Pressed cannot be true when anchored is true!
       pressed: false,
       getfeatureControl: {
           hover: true,
           drillDown: false,
           maxFeatures: 1
       },
       popupWindow: {
           title: "Information",
           hideonmove: false,
           anchored: true,
           //layer: "World Cities (FAO)",
           featureInfoPanel: {
               // Option values are 'Grid', 'Tree' and 'XML', default is 'Grid' (results in no display menu)
               displayPanels: ['Grid'],
               // Export to download file. Option values are 'CSV', 'XLS', default is no export (results in no export menu).
               exportFormats: []
               // exportFormats: ['CSV', 'XLS'],
           }
