      java.awt.Container
          java.awt.Window
              java.awt.Frame
                  javax.swing.JFrame

All Implemented Interfaces:

javax.accessibility.Accessible, java.awt.image.ImageObserver, java.awt.MenuContainer, RootPaneContainer, java.io.Serializable, WindowConstants

---

public class JFrame

extends java.awt.Frame

implements WindowConstants, RootPaneContainer, javax.accessibility.Accessible

A window that supports window decorations (titlebar and borders). This is an extension of java.awt.Frame that provides support for the Swing architecture. Most importantly it contains a JRootPane as it's only top-level child, that manages the content pane, the menu and a glass pane. Also, unlike java.awt.Frames, JFrames support the Swing Pluggable Look & Feel architecture.

                       java.lang.Object constraints,
                       int index)

Description copied from class: java.awt.Container

This method is called by all the add() methods to perform the actual adding of the component. Subclasses who wish to perform their own processing when a component is added should override this method. Any subclass doing this must call the superclass version of this method in order to ensure proper functioning of the container.

---

remove

public void remove(java.awt.Component comp)

Description copied from class: java.awt.Container

Removes the specified component from this container.

---

isRootPaneCheckingEnabled

protected boolean isRootPaneCheckingEnabled()

---

update

public void update(java.awt.Graphics g)

Description copied from class: java.awt.Container

Updates this container. The implementation of this method in this class forwards to any lightweight components in this container. If this method is subclassed, this method should still be invoked as a superclass method so that lightweight components are properly drawn.

---

processKeyEvent

protected void processKeyEvent(java.awt.event.KeyEvent e)

Description copied from class: java.awt.Component

Called when a key event is dispatched and component events are enabled. This method passes the event along to any listeners that are attached.

---

setDefaultLookAndFeelDecorated

---

isDefaultLookAndFeelDecorated

public static boolean isDefaultLookAndFeelDecorated()

---

getAccessibleContext

public javax.accessibility.AccessibleContext getAccessibleContext()

Description copied from interface: javax.accessibility.Accessible

If a component supports the Accessibility API then this method should not return null. Only classes which must extend an accessible class, but must not itself be accessible, may return null.

Specified by:

getAccessibleContext in interface javax.accessibility.Accessible

---

getDefaultCloseOperation

public int getDefaultCloseOperation()

---

paramString

protected java.lang.String paramString()

Description copied from class: java.awt.Frame

Returns a debugging string describing this window.

---

processWindowEvent

protected void processWindowEvent(java.awt.event.WindowEvent e)

Description copied from class: java.awt.Window

Dispatches this event to any listeners that are listening for WindowEvents on this window. This method only gets invoked if it is enabled via enableEvents() or if a listener has been added.

---

setDefaultCloseOperation

public void setDefaultCloseOperation(int operation)

Defines what happens when this frame is closed. Can be one off EXIT_ON_CLOSE, DISPOSE_ON_CLOSE, HIDE_ON_CLOSE or DO_NOTHING_ON_CLOSE. The default is HIDE_ON_CLOSE. When EXIT_ON_CLOSE is specified this method calls SecurityManager.checkExit(0) which might throw a SecurityException. When the specified operation is not one of the above a IllegalArgumentException is thrown.
