Changeset 5890 for code/branches/core5


Ignore:
Timestamp:
Oct 6, 2009, 5:29:39 AM (15 years ago)
Author:
landauf
Message:

Using target= instead of name= to define the target-object in EventTarget. This avoids possible loops if more than one EventTarget point to the same object, because the other EventTarget becomes a target itself, passing the event back and forth.
