This 0N/A * low-level event is generated by a Window object when it is opened, closed, 0N/A * activated, deactivated, iconified, or deiconified, or when focus is 0N/A * transfered into or out of the Window. 0N/A * The event is passed to every <code>WindowListener</code> 0N/A * or <code>WindowAdapter</code> object which registered to receive such 0N/A * events using the window's <code>addWindowListener</code> method. 0N/A * (<code>WindowAdapter</code> objects implement the 0N/A * <code>WindowListener</code> interface.) Each such listener object 0N/A * gets this <code>WindowEvent</code> when the event occurs. 217N/A * An unspecified behavior will be caused if the {@code id} parameter 217N/A * of any particular {@code WindowEvent} instance is not 217N/A * in the range from {@code WINDOW_FIRST} to {@code WINDOW_LAST}. 0N/A * @author Carl Quinn 0N/A * @author Amy Fowler 0N/A * @see WindowAdapter 0N/A * @see WindowListener 0N/A * The first number in the range of ids used for window events. 0N/A * The window opened event. This event is delivered only 0N/A * the first time a window is made visible. 0N/A * The "window is closing" event. This event is delivered when 0N/A * the user attempts to close the window from the window's system menu. 0N/A * If the program does not explicitly hide or dispose the window 0N/A * while processing this event, the window close operation will be 0N/A * The window closed event. This event is delivered after 0N/A * the window has been closed as the result of a call to dispose. 0N/A * The window iconified event. This event is delivered when 0N/A * the window has been changed from a normal to a minimized state. 0N/A * For many platforms, a minimized window is displayed as 0N/A * the icon specified in the window's iconImage property. 0N/A * @see java.awt.Frame#setIconImage 0N/A * The window deiconified event type. This event is delivered when 0N/A * the window has been changed from a minimized to a normal state. 0N/A * The window-activated event type. This event is delivered when the Window 0N/A * becomes the active Window. Only a Frame or a Dialog can be the active 0N/A * Window. The native windowing system may denote the active Window or its 0N/A * children with special decorations, such as a highlighted title bar. The 0N/A * active Window is always either the focused Window, or the first Frame or 0N/A * Dialog that is an owner of the focused Window. 0N/A * The window-deactivated event type. This event is delivered when the 0N/A * Window is no longer the active Window. Only a Frame or a Dialog can be 0N/A * the active Window. The native windowing system may denote the active 0N/A * Window or its children with special decorations, such as a highlighted 0N/A * title bar. The active Window is always either the focused Window, or the 0N/A * first Frame or Dialog that is an owner of the focused Window. 0N/A * The window-gained-focus event type. This event is delivered when the 0N/A * Window becomes the focused Window, which means that the Window, or one 0N/A * of its subcomponents, will receive keyboard events. 0N/A * The window-lost-focus event type. This event is delivered when a Window 0N/A * is no longer the focused Window, which means keyboard events will no 0N/A * longer be delivered to the Window or any of its subcomponents. 0N/A * The window-state-changed event type. This event is delivered 0N/A * when a Window's state is changed by virtue of it being 0N/A * iconified, maximized etc. 0N/A * The last number in the range of ids used for window events. 0N/A * The other Window involved in this focus or activation change. For a 0N/A * WINDOW_ACTIVATED or WINDOW_GAINED_FOCUS event, this is the Window that 0N/A * lost activation or focus. For a WINDOW_DEACTIVATED or WINDOW_LOST_FOCUS 0N/A * event, this is the Window that gained activation or focus. For any other 0N/A * type of WindowEvent, or if the focus or activation change occurs with a 0N/A * native application, a Java application in a different VM, or with no 0N/A * other Window, null is returned. 0N/A * @see #getOppositeWindow 0N/A * JDK 1.1 serialVersionUID 0N/A * Constructs a <code>WindowEvent</code> object. 217N/A * <p>This method throws an 0N/A * <code>IllegalArgumentException</code> if <code>source</code> 0N/A * is <code>null</code>. 217N/A * @param source The <code>Window</code> object 0N/A * that originated the event 217N/A * @param id An integer indicating the type of event. 217N/A * For information on allowable values, see 217N/A * the class description for {@link WindowEvent} 217N/A * @param opposite The other window involved in the focus or activation 0N/A * change, or <code>null</code> 217N/A * @param oldState Previous state of the window for window state change event. 217N/A * See {@code #getOldState()} for allowable values 217N/A * @param newState New state of the window for window state change event. 217N/A * See {@code #getNewState()} for allowable values 0N/A * @throws IllegalArgumentException if <code>source</code> is null 217N/A * @see #getOppositeWindow() 0N/A * Constructs a <code>WindowEvent</code> object with the 0N/A * specified opposite <code>Window</code>.
