I have a question regarding the getLocation() method in GEF.
When I create a component on the diagram, the getLocation() method will
return coordinate with respect to the diagram.
When I create a component on the container component, the getLocation()
method will return coordinate with respect to the container component.
But when I create a component on the diagram and then drag it to the
container component, the getLocation() method will return coordinate with
respect to the diagram. How can I find out the location of the child
component with respect to the new container component?
I think there is a method called translateToAbsolute(), but I think that
translate the coordinate to the coordinate with respect to the diagram. Is
this correct?
Thank you.

I didn't understand all of your comments. AFAIK, getLocation() *always*
returns the location with respect to the Viewer. If you think that
sometimes it is relative to the diagram, try scrolling the diagram.

The point is absolute already, so you might use translateToRelative(), but I
don't think that is sufficient either.

Thanks.
But if the parent container component has a ScrollPane itself (like teh
Circuit in Logic Editor Example), so if I first create the component on the
diagram first and the drag that to the parent container component with
Scroll Pane, the getLocation will return the location with respect to the
diagram viewer, not the parent container viewer. How can I get the location
with respect to the diagram viewer?

As Randy Hudson said getLocation() always returns the location with respect
to the Viewer.
If the component was in the diagram first and then drag and drop to a new
container (which has its own viewer), the getLocation() will return the
location respect to the diagram viewer or the new container?
