All Implemented Interfaces:

ImageObserver, MenuContainer, Serializable, Accessible, RootPaneContainer, WindowConstants
```
public class JInternalFrame
extends JComponent
implements Accessible, WindowConstants, RootPaneContainer
```
A lightweight object that provides many of the features of a native frame, including dragging, closing, becoming an icon, resizing, title display, and support for a menu bar. For task-oriented documentation and examples of using internal frames, see How to Use Internal Frames, a section in The Java Tutorial.
Generally, you add JInternalFrames to a JDesktopPane. The UI delegates the look-and-feel-specific actions to the DesktopManager object maintained by the JDesktopPane.

The JInternalFrame content pane is where you add child components. As a convenience, the add, remove, and setLayout methods of this class are overridden, so that they delegate calls to the corresponding methods of the ContentPane. For example, you can add a child component to an internal frame as follows:
```
       internalFrame.add(child);
 
```
And the child will be added to the contentPane. The content pane is actually managed by an instance of JRootPane, which also manages a layout pane, glass pane, and optional menu bar for the internal frame. Please see the JRootPane documentation for a complete description of these components. Refer to RootPaneContainer for details on adding, removing and setting the LayoutManager of a JInternalFrame.
Warning: Swing is not thread safe. For more information see Swing's Threading Policy.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the java.beans package. Please see XMLEncoder.

public void setClosable(boolean b)
```
    Sets whether this JInternalFrame can be closed by some user action.
    
    Parameters:
    
    b - a boolean value, where true means this internal frame can be closed
  - isClosable
```
public boolean isClosable()
```
    Returns whether this JInternalFrame can be closed by some user action.
    
    Returns:
    
    true if this internal frame can be closed
  - isClosed

    Returns whether this JInternalFrame is currently closed.
    
    Returns:
    
    true if this internal frame is closed, false otherwise
  - setClosed
```
public void setClosed(boolean b)
               throws PropertyVetoException
```
    Closes this internal frame if the argument is true. Do not invoke this method with a false argument; the result of invoking setClosed(false) is unspecified.
    If the internal frame is already closed, this method does nothing and returns immediately. Otherwise, this method begins by firing an INTERNAL_FRAME_CLOSING event. Then this method sets the closed property to true unless a listener vetoes the property change. This method finishes by making the internal frame invisible and unselected, and then firing an INTERNAL_FRAME_CLOSED event.
    
    Note: To reuse an internal frame that has been closed, you must add it to a container (even if you never removed it from its previous container). Typically, this container will be the JDesktopPane that previously contained the internal frame.
    
    Parameters:
    
    b - must be true
    
    Throws:
    
    PropertyVetoException - when the attempt to set the property is vetoed by the JInternalFrame

  - setIconifiable
```
public void setIconifiable(boolean b)
```
    Sets the iconable property, which must be true for the user to be able to make the JInternalFrame an icon. Some look and feels might not implement iconification; they will ignore this property.

    true if this internal frame is iconified
  - setIcon
```
public void setIcon(boolean b)
             throws PropertyVetoException
```
    Iconifies or de-iconifies this internal frame, if the look and feel supports iconification. If the internal frame's state changes to iconified, this method fires an INTERNAL_FRAME_ICONIFIED event. If the state changes to de-iconified, an INTERNAL_FRAME_DEICONIFIED event is fired.
    
    Parameters:
    
    b - a boolean, where true means to iconify this internal frame and false means to de-iconify it
    
    Throws:

```
public void setMaximizable(boolean b)
```
    Sets the maximizable property, which determines whether the JInternalFrame can be maximized by some user action. Some look and feels might not support maximizing internal frames; they will ignore this property.
    
    Parameters:
    
    b - true to specify that this internal frame should be maximizable; false to specify that it should not be
  - isMaximizable
```
public boolean isMaximizable()

public void setSelected(boolean selected)
                 throws PropertyVetoException
```
    Selects or deselects the internal frame if it's showing. A JInternalFrame normally draws its title bar differently if it is the selected frame, which indicates to the user that this internal frame has the focus. When this method changes the state of the internal frame from deselected to selected, it fires an InternalFrameEvent.INTERNAL_FRAME_ACTIVATED event. If the change is from selected to deselected, an InternalFrameEvent.INTERNAL_FRAME_DEACTIVATED event is fired.
    
    Parameters:
    
    selected - a boolean, where true means this internal frame should become selected (currently active) and false means it should become deselected

  - setFrameIcon
```
public void setFrameIcon(Icon icon)
```
    Sets an image to be displayed in the titlebar of this internal frame (usually in the top-left corner). This image is not the desktopIcon object, which is the image displayed in the JDesktop when this internal frame is iconified. Passing null to this function is valid, but the look and feel can choose the appropriate behavior for that situation, such as displaying no icon or a default icon for the look and feel.
    
    Parameters:
    
    icon - the Icon to display in the title bar
    
    See Also:

    The method may have no visual effect if the Java platform implementation and/or the native system do not support changing the mouse cursor shape.
    
    Overrides:
    
    setCursor in class Component
    
    Parameters:

```
    Returns the child component of this JInternalFrame that will receive the focus when this JInternalFrame is selected. If this JInternalFrame is currently selected, this method returns the same component as the getFocusOwner method. If this JInternalFrame is not selected, then the child component that most recently requested focus will be returned. If no child component has ever requested focus, then this JInternalFrame's initial focusable component is returned. If no such child exists, then this JInternalFrame's default component to focus is returned.
    
    Returns:
    
    the child component that will receive focus when this JInternalFrame is selected

  - setDefaultCloseOperation
```
public void setDefaultCloseOperation(int operation)
```
    Sets the operation that will happen by default when the user initiates a "close" on this internal frame. The possible choices are:
    
    DO_NOTHING_ON_CLOSE
    
    Do nothing. This requires the program to handle the operation in the internalFrameClosing method of a registered InternalFrameListener object.
    
    HIDE_ON_CLOSE
    
    Automatically make the internal frame invisible.
    
    DISPOSE_ON_CLOSE
    
    Automatically dispose of the internal frame.
    
    The default value is DISPOSE_ON_CLOSE. Before performing the specified close operation, the internal frame fires an INTERNAL_FRAME_CLOSING event.
    
    Parameters:
    
    operation - one of the following constants defined in javax.swing.WindowConstants (an interface implemented by JInternalFrame): DO_NOTHING_ON_CLOSE, HIDE_ON_CLOSE, or DISPOSE_ON_CLOSE

    addInternalFrameListener(javax.swing.event.InternalFrameListener), getDefaultCloseOperation(), JComponent.setVisible(boolean), dispose(), InternalFrameEvent.INTERNAL_FRAME_CLOSING
  - getDefaultCloseOperation
```
public int getDefaultCloseOperation()
```
    Returns the default operation that occurs when the user initiates a "close" on this internal frame.
    
    Returns:
    
    the operation that will occur when the user closes the internal frame
    
    See Also:
    
    setDefaultCloseOperation(int)
  - pack
```
public void pack()
```
    Causes subcomponents of this JInternalFrame to be laid out at their preferred size. Internal frames that are iconized or maximized are first restored and then packed. If the internal frame is unable to be restored its state is not changed and will not be packed.
    
    See Also:
    
    Window.pack()
  - show
```
public void show()
```
    If the internal frame is not visible, brings the internal frame to the front, makes it visible, and attempts to select it. The first time the internal frame is made visible, this method also fires an INTERNAL_FRAME_OPENED event. This method does nothing if the internal frame is already visible. Invoking this method has the same result as invoking setVisible(true).
    
    Overrides:
    
    show in class Component
    
    See Also:
    
    moveToFront(), setSelected(boolean), InternalFrameEvent.INTERNAL_FRAME_OPENED, JComponent.setVisible(boolean)
  - hide
```
public void hide()
```
    Description copied from class: JComponent
    
    Overrides:
    
    hide in class JComponent
  - dispose
```
public void dispose()
```
    Makes this internal frame invisible, unselected, and closed. If the frame is not already closed, this method fires an INTERNAL_FRAME_CLOSED event. The results of invoking this method are similar to setClosed(true), but dispose always succeeds in closing the internal frame and does not fire an INTERNAL_FRAME_CLOSING event.
    
    See Also:
    
    InternalFrameEvent.INTERNAL_FRAME_CLOSED, JComponent.setVisible(boolean), setSelected(boolean), setClosed(boolean)
  - toFront
```
public void toFront()
```
    Brings this internal frame to the front. Places this internal frame at the top of the stacking order and makes the corresponding adjustment to other visible internal frames.
    
    See Also:
    
    Window.toFront(), moveToFront()
  - toBack
```
public void toBack()
```
    Sends this internal frame to the back. Places this internal frame at the bottom of the stacking order and makes the corresponding adjustment to other visible internal frames.
    
    See Also:
    
    Window.toBack(), moveToBack()
  - setFocusCycleRoot
```
public final void setFocusCycleRoot(boolean focusCycleRoot)
```
    Does nothing because JInternalFrames must always be roots of a focus traversal cycle.
    
    Overrides:
    
    setFocusCycleRoot in class Container
    
    Parameters:
    
    focusCycleRoot - this value is ignored
    
    Since:
    
    1.4
    
    See Also:
    
    isFocusCycleRoot(), Container.setFocusTraversalPolicy(java.awt.FocusTraversalPolicy), Container.getFocusTraversalPolicy()
  - isFocusCycleRoot
```
public final boolean isFocusCycleRoot()
```
    Always returns true because all JInternalFrames must be roots of a focus traversal cycle.
    
    Overrides:
    
    isFocusCycleRoot in class Container
    
    Returns:
    
    true
    
    Since:
    
    1.4
    
    See Also:
    
    setFocusCycleRoot(boolean), Container.setFocusTraversalPolicy(java.awt.FocusTraversalPolicy), Container.getFocusTraversalPolicy()
  - getFocusCycleRootAncestor
```
public final Container getFocusCycleRootAncestor()
```
    Always returns null because JInternalFrames must always be roots of a focus traversal cycle.
    
    Overrides:
    
    getFocusCycleRootAncestor in class Component
    
    Returns:
    
    null
    
    Since:
    
    1.4
    
    See Also:
    
    Container.isFocusCycleRoot()
  - getWarningString
```
public final String getWarningString()
```
    Gets the warning string that is displayed with this internal frame. Since an internal frame is always secure (since it's fully contained within a window that might need a warning string) this method always returns null.
    
    Returns:
    
    null
    
    See Also:
    
    Window.getWarningString()
  - paramString
```
protected String paramString()
```
    Returns a string representation of this JInternalFrame. This method is intended to be used only for debugging purposes, and the content and format of the returned string may vary between implementations. The returned string may be empty but may not be null.
    
    Overrides:
    
    paramString in class JComponent
    
    Returns:
    
    a string representation of this JInternalFrame
  - paintComponent
```
protected void paintComponent(Graphics g)
```
    Overridden to allow optimized painting when the internal frame is being dragged.
    
    Overrides:
    
    paintComponent in class JComponent
    
    Parameters:
    
    g - the Graphics object to protect
    
    See Also:
    
    JComponent.paint(java.awt.Graphics), ComponentUI
  - getAccessibleContext
```
public AccessibleContext getAccessibleContext()
```
    Gets the AccessibleContext associated with this JInternalFrame. For internal frames, the AccessibleContext takes the form of an AccessibleJInternalFrame object. A new AccessibleJInternalFrame instance is created if necessary.
    
    Specified by:
    
    getAccessibleContext in interface Accessible
    
    Overrides:
    
    getAccessibleContext in class Component
    
    Returns:
    
    an AccessibleJInternalFrame that serves as the AccessibleContext of this JInternalFrame
    
    See Also:
    
    JInternalFrame.AccessibleJInternalFrame
