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. */ public class ComponentReshapeEvent extends AWTEvent { public int x; public int y; public int width; public int height; public ComponentReshapeEvent(Component c, int x, int y, int width, int height) { super(c, 1999); this.x = x; this.y = y; this.width = width; this.height = height; } }
