[OpenLayers-Users] OpenLayers.Control.Button with displayClass

[Casper Span]

Michael,

A OpenLayers.Control.Button only has one state: inactive. As soon as you
click it (triggering the 'trigger' function) it returns to it's inactive
state.
If you want it to toggle, you should create a OpenLayers.Control override.

You could do that by creating an OpenLayers.Control and adding some events:
http://dev.openlayers.org/releases/OpenLayers-2.11/examples/custom-control.html

Or by going into the code and create your own classes.

Hope this helps!


Regards,
Casper
