How to generate an event

Habanero.sendEvent()

Background Information

Sometimes you want to generate a new event, apart from events users cause. At other times, a user may cause some event, but you want to propagate a different kind of event.

For example, the user could press a button and you want to send the contents of a field instead of the normal button event.

How does this work?

To generate a new event, call the method Habanero.sendEvent(AWTEvent), passing it the event you want to send.

Example

protected void processActionEvent(ActionEvent e)
{ if (e.getSource() != null)
{ Habanero.sendEvent(e);
}
else
// Deal with the case of there being no source.
}
