Hi all,
I have a GriddedSet with 4 datareferences. Each datareference has
arrows/flows in another direction and also a
PickManipulationRendererJ3D. But if I click on the arrows, only the left
one shoots an event and only a small piece of the arrow is sensitive. In
attachment you can find a test program.
Someone a suggestion?
Regards,
Geert.
