Hi,

I am trying to develop an editor containing several components on the
palette that can be dragged on the canvas. I am trying to develop the same
on the lines of gef logic example. Can you please tell me the control flow
of this statement.

getHost().getParent().

present in LogicElementEditPolicy in the edit package. This statement
returns an object of LogicDiagramEditPart but in my case a similar
statement is returning ScalableFreeformRootEditPart.

Can anybody please tell me the control flow being followed here to return
LogicDiagramEditPart.

awaiting an early response

thanks and regards

getHost returns the edit part your edit policy is attached to. getParent
method of the editPart returns the edit part that has the given part as a
child. In your case you call getParent of the edit part that is the root of
your model (i.e. LogicDiagramEditPart).
To get the LogicDiagramEditPart in the uniform way you can either look in
the edit part registry (this wil isolate you from the later changes).
