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

Betreff: RE: [Users] Add overview map to mappanel
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
