Also, you could concentrate on your css styles. I really don't understand them, but they have something to do with the functioning. If I add 'ItemInactive' into your style in Firebug, the button works. Maybe *someone could explain* this button thing to us who don't get it. I have been using the following styles and activating/deactivating my buttons by demand. .olControlPanel div { display:block; width: 24px; height: 24px; margin: 5px; background-color:red; position: absolute; top: 100px; left: 10px; } .olControlPanel .infoItemActive { background-color: green; background-image: url("./OpenLayers-2.7/info_on.png"); position: absolute; top: 140px; left: 10px; } .olControlPanel .infoItemInactive { background-color: blue; background-image: url("./OpenLayers-2.7/info_off.png"); position: absolute; top: 140px; left: 10px; } Of course you have to change the displayClass ( Mine is 'info' in this example.) This cretes two-state button (different image when on and off). - mika - Arnd Wippermann kirjoitti: Hi, Perhaps you have to activate the control: panel.activateControl(button);Arnd Wippermann -----Ursprüngliche Nachricht----- Von: users-boun...@openlayers.org [mailto:users-boun...@openlayers.org] Im Auftrag von JuergenL Gesendet: Dienstag, 3.

The button is visible but nothing happens when I click on it. That's how I define the button: var panel = new OpenLayers.Control.Panel(); var button = new OpenLayers.Control.Button({displayClass: "addMarkerBtn", trigger: addMarker}); panel.addControls([button]); map.addControl(panel); And the function addMarker: addMarker = function() { alert('test'); } I also tried function addMarker() { alert('test'); } Here is a complete test page: http://albspotter.org/osm/test.php Can anyone tell why this doesn't work?
