Class AreaOwner<Parent,Owner>

java.lang.Object

org.apache.hop.core.gui.AreaOwner<Parent,Owner>

public class AreaOwner<Parent,Owner>
extends Object

When we draw something in HopGui PipelinePainter or WorkflowPainter we keep a list of all the things we draw and the object that's behind it. That should make it a lot easier to track what was drawn, setting tooltips, etc.
