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.

Returns whether this JInternalFrame can be closed by some user action.
true if this internal frame can be closedpublic boolean isClosed()
Returns whether this JInternalFrame is currently closed.
true if this internal frame is closed, false otherwisepublic 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.

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.

public boolean isSelected()
Returns whether the JInternalFrame is the currently "selected" or active frame.
true if this internal frame is currently selected (active)setSelected(boolean)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.
icon - the Icon to display in the title bargetFrameIcon()public Icon getFrameIcon()
Returns the image displayed in the title bar of this internal frame (usually in the top-left corner).

public void moveToBack()
Convenience method that moves this component to position -1 if its parent is a JLayeredPane.
public Cursor getLastCursor()
Returns the last Cursor that was set by the setCursor method that is not a resizable Cursor.
Cursor
public void setCursor(Cursor cursor)
Sets the cursor image to the specified cursor. This cursor image is displayed when the contains method for this component returns true for the current cursor location, and this Component is visible, displayable, and enabled. Setting the cursor of a Container causes that cursor to be displayed within all of the container's subcomponents, except for those that have a non-null cursor.
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.

Sets the normal bounds for this internal frame, the bounds that this internal frame would be restored to from its maximized state. This method is intended for use only by desktop managers.
r - the bounds that this internal frame should be restored topublic Component getFocusOwner()
If this JInternalFrame is active, returns the child that has focus. Otherwise, returns null.
null if no children have focuspublic Component getMostRecentFocusOwner()
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.
JInternalFrame is selectedgetFocusOwner(), isSelected
public void restoreSubcomponentFocus()
Requests the internal frame to restore focus to the last subcomponent that had focus. This is used by the UI when the user selected this internal frame -- for example, by clicking on the title bar.
public void reshape(int x,
int y,
int width,
int height) Moves and resizes this component. Unlike other components, this implementation also forces re-layout, so that frame decorations such as the title bar are always redisplayed.

Fires an INTERNAL_FRAME_CLOSING event and then performs the action specified by the internal frame's default close operation. This method is typically invoked by the look-and-feel-implemented action handler for the internal frame's close button.
setDefaultCloseOperation(int), InternalFrameEvent.INTERNAL_FRAME_CLOSING
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 internalFrameClosing method of a registered InternalFrameListener object. HIDE_ON_CLOSE DISPOSE_ON_CLOSE The default value is DISPOSE_ON_CLOSE. Before performing the specified close operation, the internal frame fires an INTERNAL_FRAME_CLOSING event.

addInternalFrameListener(javax.swing.event.InternalFrameListener), getDefaultCloseOperation(), JComponent.setVisible(boolean), dispose(), InternalFrameEvent.INTERNAL_FRAME_CLOSING
public int getDefaultCloseOperation()
Returns the default operation that occurs when the user initiates a "close" on this internal frame.
setDefaultCloseOperation(int)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.
Window.pack()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).

public void hide()
Description copied from class: JComponent
hide in class JComponent
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.
InternalFrameEvent.INTERNAL_FRAME_CLOSED, JComponent.setVisible(boolean), setSelected(boolean), setClosed(boolean)
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.

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.
nullWindow.getWarningString()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.
