Event redirection within face hierachies (View//Face] [View//Event]

Hi James, JM> As the control overlay is the topmost (active) window it is receiving JM> the events. If these events are not triggering a subcontrol located on JM> the control face then these event need to be propagated downwards to the JM> plan screen for final input to be analysed and acted upon. If the pilot JM> clicks in the control overlay this plots a point on the map - clicking JM> and holding the mouse down will draw a dynamic line which will get JM> placed once an up event is received. I don't know anything about the internals, but I wouldn't be surprised if RT set things up to allow--someday--the ability to hook into the event chain "for real"; it isn't there today though. What I wonder is whether you need to do it at all in this case. i.e. can you take the events and operate directly against the data that is being used to render the overlays, updating associated faces if necessary? That would give you more control over how things are done, where events can come from, etc. -- Gregg
