No. Sadly (or luckily, depending on one's point of view) a widget is
not an ordinary control. This has to be implemented in the widget.

To see this write one that handles only the mouse events, not to
speak of a clickable region.
Even this is hard to control: who gets first which mouseEvent, the
widget's script or the widget.

I’m thinking that a single line of code would suffice:

set the clickableRegion of widget “Fred” to ListOfPoints

As i’ve noted previously, the engine *already* handles clickable regions for 
*every* control, and my proposal ‘merely’ (he says, optimistically…) opens up 
the engine’s mechanisms to the extent of granting developers the opportunity to 
override the engine’s default “define the clickable region” behavior. If a dev 
is happy with the default clickable regions provided by the engine, that dev 
can just ignore the clickableRegion property and everything should work the 
same as it always did… but if a dev *isn’t* happy with the default clickable 
regions provided by the engine, *then* that dev can mess around with the 
clickableRegion property.
