[Users] Add overview map to mappanel

[Robert Buckley]

Hi,

I actually got it working...but....due to the fact that my basemaps come from geowebcache, the resolution is the same as the map...ie...too big for an overviewmap.

How could I use an image to do this?...does this possibility exist?

yours,

Rob

Hi,

Thanks for the example.....it kind of works, but the map is dark blue, and my layers are not displayed!

cheers,

Rob

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
