I am trying to check if a button is clicked in the Measurement widget. Any ideas on how to do this?
I want to do something when the extent is active
Which widget is this. It does not look like the OTB Measurement widget or Tom's custom Measure widget...?
you can just check the dom for a specific class name assuming it is using css class to change the look.
If you are unable to get a handle to the dom, you can try using https://dojotoolkit.org/reference-guide/1.9/dojo/query.html
