Add listener for event
Syntax
el = addlistener(hsource, 'eventname', callback)
el = addlistener(hsource, property, 'eventname', callback)
Description
el = addlistener(hsource, 'eventname', callback) creates
a listener for the event named eventname, the source
of which is handle object hsource. If hsource is
an array of source handles, the listener responds to the named event
on any handle in the array. callback
is a function handle that is invoked when the event is triggered.
el = addlistener(hsource, property, 'eventname', callback) adds
a listener for a property event. eventname must
be one of the strings 'PreGet', 'PostGet', 'PreSet',
and 'PostSet'. property must
be either a property name or cell array of property names, or a meta.property or
array of meta.property. The properties must belong
to the class of hsource. If hsource is
scalar, property can include dynamic properties.
For all forms, addlistener returns an event.listener.
To remove a listener, delete the object returned by addlistener.
For example, delete(el) calls the handle class
delete method to remove the listener and delete it from the workspace.
