## 18.61 java.awt.Window (JDK 1.0)

###

This class represents a top-level window with no borders or menu bar. `Window` is a `Container` with `BorderLayout` as its default layout manager. `Window` is rarely used directly; its subclasses `Frame` and `Dialog` are more commonly useful.

`show()` (which overrides `Component.show()`) makes a `Window` visible and brings it to the front of other windows. `toFront()` brings a window to the front, and `toBack()` buries a window beneath others. `pack()` is an important method that initiates layout management for the window, and sets the window size to match the preferred size of the components contained within the window. `getToolkit()` returns the `Toolkit()` in use for this window. Call `dispose()` when a `Window` is no longer needed to free its window system resources.

    public class Window extends Container {
        // Public Constructor
                public Window(Frame parent);
        // Public Instance Methods
                public void addNotify();  // Overrides Container
            1.1  public synchronized void addWindowListener(WindowListener l);
                public void dispose();
            1.1  public Component getFocusOwner();
            1.1  public Locale getLocale();  // Overrides Component
                public Toolkit getToolkit();  // Overrides Component
                public final String getWarningString();
            1.1  public boolean isShowing();  // Overrides Component
                public void pack();
            1.1  public boolean postEvent(Event e);  // Overrides Component
            1.1  public synchronized void removeWindowListener(WindowListener l);
                public void show();  // Overrides Component
                public void toBack();
                public void toFront();
        // Protected Instance Methods
            1.1  protected void processEvent(AWTEvent e);  // Overrides Container
            1.1  protected void processWindowEvent(WindowEvent e);
    }
