[Users] Add overview map to mappanel

[Andrew Stewart]

First make a new window to hold the overview map, put the function as the listener for "after_layout". Here is how I declare mine -


overview_window = new Ext.Window({
        title: "Overview Window",
        bodyBorder: false,
        closeAction: "hide",
        collapsible: true,
        titleCollapse: true,
        width: 200,
        resizable: false,
        closable: false,
        html: '<div id="overviewmap"></div>',
        listeners: {
            afterlayout: {
                fn: addOverview,
                single: true
            }
        }
    });
    overview_window.show();
    overview_window.alignTo(document.body, "bl", [10, -125]);

    function addOverview() {
    var b = {
        div: Ext.get("overviewmap"),
        mapOptions: {
            maxResolution: 190,
            minResolution: 190,
            numZoomLevels: 1
        },
        id: "overview_map",
        layers: [layer_Overview.clone()]
    },
        a = new OpenLayers.Control.OverviewMap(b);
        a.isSuitableOverview = function () {
        return true
    };
        map.addControl(a)
    }

Subject: [Users] Add overview map to mappanel

Hi,

I want to add an overviewmap with an rectangle showing the current extent of the mappanel and one wms layer as reference.

I read this...

http://www.geoext.org/pipermail/users/2010-February/000593.html

But cannot see where the following should be place...



addOverview: = function() {

                 var mapOptions = {
                     maxExtent: new OpenLayers.Bounds(180000, 397000,200000,
 414000),
                     maxResolution: 500,
                     projection: "EPSG:28992",
                     units: "m"
                 };



..is this part of a panel, or the mappanel?


does anyone know where this should go...or is there a better method to produce a simple yet effective overview map?


Rob
