anyway, so that the user knows that the item is viewable ?. I use easeljs but did not find anything related
You can use this: How to make clickable points in html5 canvas?
and while the mouse is in this area, you can set: $('#canvasID').css('cursor','pointer') and $('#canvasID').css('cursor','auto') , when she is not above him.
$('#canvasID').css('cursor','pointer')
$('#canvasID').css('cursor','auto')
I use Easeljs and get the cursor pointer. I use myObject.cursor = 'pointer' and stage.enableMouseOver(20); (from the sample example DragAndDrop.html).
myObject.cursor = 'pointer'
stage.enableMouseOver(20);
