I am attempting to place a CellEditorLocator class implementation over a
figure inside a parent figure during a
org.eclipse.gef.EditPart.performRequest( Request ) call. The Request type
casts to a DirectEditRequest. In the code I call the EditPart's
getFigure().findFigureAt() using the location from
DirectEditRequest.getLocation().
All works fine until I zoom the editor. Then it seems the
DirectEditRequest.getLocation() is scaled, so the findFigureAt() call fails.
Is there a bug here, or should I be doing something different? Can I get
the current zoom inside this call?
Thank you,
Brett

All request locations are absolute. You'll need to convert to relative first
by using:
getFigure().translateToRelative(locationCopy);

That works. Thank you.
I guess I had the concept of absolute and relative backwards. I thought
absolute would be the non-scaled coordinates, and relative would be the
scaled. It appears that this is not the case.
So, absolute == scaled values, and relative == non-scaled.

Absolute is where the coordinate appears "relative" to the absolute parent,
the root figure.
