Hi Shekhar,

  If I understand correctly, you have 1 (or more) elements on the canvas and
you would like to highlight the clicked one and unhighlight when the
background is clicked.  The below assumes that...

One method is to add a "glass pane" to the canvas in order to capture the
"off" events.

Add a <g> behind all other elements.
ensure that the <g> tag pointer-events="all" or other (see
http://www.w3.org/TR/SVG/interact.html#PointerEventsProperty)
Add a listener for the <g>

you'll have to manage the event bubbling with this method, but it is pretty
easy to implement


Hope this helps,


Jonathan
