Class ComponentReshapeEvent

Implemented Interfaces:
Serializable
public class ComponentReshapeEvent
extends AWTEvent
This is used to update the AWT's knowledge about a Window's size when the user changes the window bounds. This event is _not_ posted to the eventqueue, but rather dispatched directly via Window.dispatchEvent(). It is the cleanest way we could find to update the AWT's knowledge of the window size. Small testprograms showed the following: - Component.reshape() and its derivatives are _not_ called. This makes sense as it could end up in loops,because this calls back into the peers. - Intercepting event dispatching for any events in EventQueue.dispatchEvent() showed that the size is still updated. So it is not done via an event dispatched over the eventqueue. Possible other candidates for implementation would have been: - Call a (private) callback method in Window/Component from the native side. - Call a (private) callback method in Window/Component via reflection. Both is uglier than sending this event directly. Note however that this is impossible to test, as Component.dispatchEvent() is final and can't be intercepted from outside code. But this impossibility to test the issue from outside code also means that this shouldn't raise any compatibility issues.
