Hi,
Can someone please tell me how to use ConnectionLayer in GEF? Is there an
example somewhere? From the javadoc, it is a layer for connection and
primary layer is for figures. If I want all figures on top of all
Connections, do I need to have 1 connection layer and 1 primary layer? if
yes, where should I create and add those layers to? to the main editor?
thanks for any help.

Could you please what is the best approach to make Connections behind
figures and invisible when they overlap? And both connections and figures
are visible when they are not overlap?
