Try creating a subclass of CSpButton and implement the processWebEvent():
protected void processWebEvent(CSpWebEvent ev)throws CSpSkipException, CSpStopException
{
if (ev.getId() == CSpWevEvent.ON_WEB_EVENT)
{
// code that executes
// before the listeners
}
super.processWebEvent(ev);
if (ev.getId() == CSpWevEvent.ON_WEB_EVENT)
{
// code that executes
// after the listeners
}
}
It appears that the event dispatching is done similar to the AWT.
For the event of type CSpXXXEvent the class that can dispatch that type of event has
the methods addXXXListener(), removeXXXListener(), processXXXEvent(). The
class overrides
the processEvent() like this:
protected processEvent(CSpEvent ev)
{
if (ev instanceOf CSpXXXEvent) {
processXXXEvent((CSpXXXEvent)ev);
}
else {
super.processEvent(ev);
}
}
protected processXXXEvent(CSpXXXEvent ev)
{
switch (ev.getId()) {
case MY_EVENT_ID_1:
_XXXListeners.eventMethod1(ev);
case MY_EVENT_ID_2:
_XXXListeners.eventMethod2(ev);
default:
// log error ?
}
}
Beware that events are not dispatched unless they are enabled - there is an event
mask that prevents events dispatching by type if there are no listeners for
them.
So do not expect that processXXXEvent() will be called unless the event is
enabled
programatically or there are listeners attached for it in that component.
