javax.swing
Class JFrame
- Accessible, ImageObserver, MenuContainer, RootPaneContainer, Serializable, WindowConstants
A window that supports window decorations (titlebar and borders).
This is an extension of
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.

JFrame
public JFrame()
Creates a new frame with an empty string for the title.
JFrame
public JFrame(String title)
Creates a new JFrame with the specified title.
title - the frame title (null permitted).
addImpl
protected void addImpl(Component comp,
Object constraints,
int index) 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.
- addImpl in interface Container
comp - The component to be added.constraints - The layout constraints for this component, or
null if there are no constraints.index - The index in the component list to insert this child
at, or -1 to add at the end of the list.
paramString
protected String paramString()
Returns a string describing the attributes for the JFrame,
for use in debugging. The return value is guaranteed to be
non-null, but the format may vary between implementations.
- paramString in interface Frame
- A string describing the attributes of the
JFrame.
processKeyEvent
protected void processKeyEvent(KeyEvent e)
Called when a key event is dispatched and component events are
enabled. This method passes the event along to any listeners
that are attached.
- processKeyEvent in interface Component
e - the KeyEvent to process
processWindowEvent
protected void processWindowEvent(WindowEvent e)
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.
- processWindowEvent in interface Window
remove
public void remove(Component comp)
Removes the specified component from this container.
- remove in interface Container
comp - The component to remove from this container.
setDefaultCloseOperation
public void setDefaultCloseOperation(int operation)
Sets the default operation that is performed when this frame is closed.
The default is HIDE_ON_CLOSE. When
EXIT_ON_CLOSE is specified this method calls
SecurityManager.checkExit(0) which might throw a
SecurityException.
update
public void update(Graphics g)
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.
- update in interface Container
g - The graphics context for this update.
