[Users] Loadmask

[Andreas Hocevar]

Hi,

try something like

var loadMask = new Ext.LoadMask(Ext.getBody(),{
    msg:"Loading Layer. Please wait."
});
loadMask.show();
var numLoadingLayers = layerStore.getCount();
function checkLoaded() {
    layer.events.unregister("loadend", checkLoaded, this);
    numLoadingLayers--;
    if (numLoadingLayers === 0) {
        loadMask.hide();
    }
}

layerStore.each(function(rec) {
    var layer = rec.getLayer();
    layer.events.register("loadend", checkLoaded, layer);
});

This has to run before the layers from the layerStore are added to the
map. And note that the above is untested, but it should point you in
the right direction.

Andreas.
