dabo Commit
Revision 1275
Date: 2005-09-08 23:00:04 -0700 (Thu, 08 Sep 2005)
Author: paul
Changed:
U trunk/dabo/common/eventMixin.py
Log:
Added functionality for the auto event bindings to look for and
attach to functions in the form object of the form:
on<Event>_<Object.RegId>
If found, the event binding will happen like:
<Object>.bindEvent(<Event>, Form.on<Event>_<Object.Regid>)
Note that if we decide to move forward with this, we should
disallow the _ character from being part of RegId, and we must
never use the _ character in dEvent names.
