You can use:

        yourView.getAttributeRelative('x',canvas);
        yourView.getAttributeRelative('y',canvas);

Ouch! on the nail, thanks Andy.

LzView.getAttributeRelative will do the job.

I just wrote something like this, but I think it has the same bug as 3.3:

 <method name="getGlobal" args="obj,attr">
   var rv = obj[attr];
   while(true) {
     if(obj instanceof lz.canvas) {
       return(rv);
     }
     obj = obj.parent;
     rv += obj[attr];
   }
 </method>

Details of getAttributeRelative are in reference documentation for view.
There is a bug (at version 3.3) in which this does not return the
correct answer if there is a scaled view in "yourView" hierarchy.

Cheers,

Andy

Hi,

Is there any way to know the absolute x and y canvas coordinates of a view whose parent is not the canvas without traversing down the parents hierarchy?

Thanks in advance,
