Openlayers controls outside the map

Question

I want put OpenLayers controls outside a map but dont know how. I find this example http://openlayers.org/dev/examples/editingtoolbar-outside.html but its not what i want. I have a button and want to edit my WFS layer by click this button. So i need in

OpenLayers.Control.ModifyFeature(wfs, {
    title: "Modify Feature",
    displayClass: "olControlModifyFeature"
});

So how to put this in button? And i use a geoext.

I did not go through that problem yet, but what you are asking maybe similar to this: http://lists.osgeo.org/pipermail/openlayers-users/2007-October/003093.html

Solution :

                         editButton= new Ext.Button({
                                tooltip: "Edit",
                                id: "commit_changes",
                                text: "Edit",
                                hidden: false,
                                handler: function(){
create= new OpenLayers.Control.DrawFeature(myVecLayer,
                                            OpenLayers.Handler.Polygon);
                                    app.mapPanel.map.addControl(create);
                                    create_cont=app.mapPanel.map.getControlsByClass("OpenLayers.Control.DrawFeature");
                                }

                           }

Something like this. Some controls needed for activate option.
