Direct Known Subclasses:

SunJDK140ConditionalEventPump, SunJDK141ConditionalEventPump

public class SunJDK14ConditionalEventPump
extends ConditionalEventPump
implements EventFilterable

Specialized ConditionalEventPump for Sun's JDK 1.4 and 5.0. It fixes what I think is a misbehavior of EventQueue.peekEvent(), that does not flush pending events to the EventQueue before peeking for them.

Method Detail

peekEvent

protected java.awt.AWTEvent peekEvent(java.awt.EventQueue queue)

Flushes pending events before peeking the EventQueue. There is a mismatch between the behavior of EventQueue.getNextEvent() and EventQueue.peekEvent(): the first always flushes pending events, the second does not. This missing flushing is the reason why peekEvent() returns null causing the proxy implementation of Conditional.evaluate() to never return
