class core.world.world.World

Bases: openalea.core.scene.vplscene.VPLScene, openalea.grapheditor.observer.AbstractListener

Contain objects of the world.

When world changes, several events can be notified to listeners:

• world_object_changed(world, changes)
• world_object_replaced(world, key, old_object, new_object)
• world_object_added(world, key, new_object)
• world_object_removed(world, old_object)

A generic "world_changed" event is also notified for all previous changes.

Warning

currently only world_changed event is implemented
