is it the view's responsibility to know which RESPONSE it should send
to when an UI interaction occurs?

can someone explain what happens in GEF behind a user opertion(for example
, dragging a handle to resize a Figure). since the REQUEST is just a
constant
,where does GEF get the mouse position and keyborad state?

A ResizeTracker maintains this information and passes it using a subclass of
Request.
