Constructor Detail

CacioEventPump

protected CacioEventPump()

Creates and starts a CacioEventPump with the specified event source.

Parameters:

s - the event source to get events from

Method Detail

start

protected void start()

run

public final void run()

The main loop of the event pump.

Specified by:

run in interface Runnable

fetchNativeEvent

protected abstract ET fetchNativeEvent()
                                throws InterruptedException

Fetches the next native event. This method is called in an AWT Autoshutdown free block, that means, as long as the thread is in this method, it doesn't prevent shutting down AWT. Therefore, this method should only wait for the next native event and return it as soon as possible. Implement dispatchNativeEvent for dispatching the event.

Returns:

the native event

Throws:

InterruptedException

dispatchNativeEvent

protected abstract void dispatchNativeEvent(ET nativeEvent)

Dispatches the native event. This method is called in an AWT Autoshutdown busy block, that means, as long as the thread is in this method, it prevents shutting down AWT.

Parameters:

nativeEvent -

postMouseEvent

protected final void postMouseEvent(CacioComponent source,
                  int id,
                  long time,

                  int y,
                  int clickCount,
                  boolean popupTrigger)

postKeyEvent

protected final void postKeyEvent(CacioComponent source,
