[OpenLayers-Users] Button Active CSS Styling

[Kris Geusebroek]

Hi Henry,

In your code I can see the button is added to the panel but is the panel
also added to the map?
And also the button needs to be activated to get the active style
In the activate method a check is made that the map is set on the
control

        if(this.map) {
            OpenLayers.Element.addClass(
                this.map.viewPortDiv,
                this.displayClass.replace(/ /g, "") + "Active"
            );
        }

Cheers Kris

Hey Kris,

first of all thanks for your help.

Unfortunately this hasn't changed anything.

Here is changed code for the button:
var btn = new $wnd.OpenLayers.Control.Button
({trigger:  myTrigger,
title: 'Enable or Disable the Area of Interest Selection',
displayClass: 'olControlButton'});

Bye Henry
