public interface EventAcceptor
extends CanvasComponent
```
An event acceptor is a canvas component object that is prepared to accept an AWT event, and then possibly process and consume it. This interface is also used as a tagging interface so that event-processing routines can tell whether certain objects are smart enough to handle events for themselves.

- Method Detail
  - isEnabled
```
boolean isEnabled()
```
    Test the enabled flag of this object. If true, the object is prepared to handle events with processEvent().
    
    Returns:
    
    true if the object is prepared to handle events with processEvent()
  - setEnabled
```
void setEnabled(boolean flag)
```
    Set the enabled flag of this object. If true, the object is prepared to handle events with processEvent().
    
    Parameters:
    
    flag - True if the object is prepared to handle events with processEvent();
  - dispatchEvent
```
void dispatchEvent(java.awt.AWTEvent event)
```
    Dispatch an AWT event within this component. The implementing object should test if it is enabled first, and return if not. Otherwise, it should handle the event in whatever way it thinks appropriate.
    
    Parameters:
    
    event - the event.
