Class Overview

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 conveniance add and its variants, remove and setLayout have been overridden to forward to the contentPane as necessary. This means you can write:

       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^TM has been added to the java.beans package. Please see XMLEncoder.

public 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.

Returns

the child component that will receive focus when this JInternalFrame is selected

Returns

null

public void hide ()

This method is deprecated.
As of JDK version 1.1, replaced by setVisible(boolean).

public boolean isClosable ()

Returns whether this JInternalFrame can be closed by some user action.

Returns

true if this internal frame can be closed

public boolean isClosed ()

Returns whether this JInternalFrame is currently closed.

Parameters

comp	the component to be removed

Throws

NullPointerException	if `comp` is null

public void removeInternalFrameListener (InternalFrameListener l)

Removes the specified internal frame listener so that it no longer receives internal frame events from this internal frame.

Parameters

l	the internal frame listener

public void reshape (int x, int y, int width, int height)

This method is deprecated.
As of JDK 5, replaced by Component.setBounds(int, int, int, int).

Moves and resizes this component.

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.

Parameters

x	an integer giving the component's new horizontal position measured in pixels from the left of its container
y	an integer giving the component's new vertical position, measured in pixels from the bottom of its container
width	an integer giving the component's new width in pixels
height	an integer giving the component's new height in pixels

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 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

public void setClosed (boolean b)

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`

public void setContentPane (Container c)

Sets this JInternalFrame's contentPane property.

Parameters

c	the content pane for this internal frame

Throws

IllegalComponentStateException	(a runtime exception) if the content pane parameter is `null`

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.

Parameters

cursor	One of the constants defined by the `Cursor` class; if this parameter is `null` then this component will inherit the cursor of its parent

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 windowClosing 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`

public void setDesktopIcon (JInternalFrame.JDesktopIcon d)

Sets the JDesktopIcon associated with this JInternalFrame.

Parameters

d	the `JDesktopIcon` to display on the desktop

public final void setFocusCycleRoot (boolean focusCycleRoot)

Does nothing because JInternalFrames must always be roots of a focus traversal cycle.

Parameters

focusCycleRoot	this value is ignored

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

public void setGlassPane (Component glass)

Sets this JInternalFrame's glassPane property.

Parameters

glass	the glass pane for this internal frame

public void setIcon (boolean b)

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

PropertyVetoException	when the attempt to set the property is vetoed by the `JInternalFrame`

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.

Parameters

b	a boolean, where `true` means this internal frame can be iconified

public void setJMenuBar (JMenuBar m)

Sets the menuBar property for this JInternalFrame.

Parameters

m	the `JMenuBar` to use in this internal frame

public void setLayer (Integer layer)

Convenience method for setting the layer attribute of this component.

Parameters

layer	an `Integer` object specifying this frame's desktop layer

public void setLayer (int layer)

Convenience method for setting the layer attribute of this component. The method setLayer(Integer) should be used for layer values predefined in JLayeredPane. When using setLayer(int), care must be taken not to accidentally clash with those values.

Parameters

layer	an integer specifying this internal frame's desktop layer

public void setLayeredPane (JLayeredPane layered)

Sets this JInternalFrame's layeredPane property.

Parameters

layered	the `JLayeredPane` for this internal frame

Throws

IllegalComponentStateException	(a runtime exception) if the layered pane parameter is `null`

public void setLayout (LayoutManager manager)

Ensures that, by default, the layout of this component cannot be set. Overridden to conditionally forward the call to the contentPane. Refer to RootPaneContainer for more information.

Parameters

manager	the `LayoutManager`

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

public void setMaximum (boolean b)

Maximizes and restores this internal frame. A maximized frame is resized to fully fit the JDesktopPane area associated with the JInternalFrame. A restored frame's size is set to the JInternalFrame's actual size.

Parameters

b	a boolean, where `true` maximizes this internal frame and `false` restores it

Throws

PropertyVetoException	when the attempt to set the property is vetoed by the `JInternalFrame`

public void setMenuBar (JMenuBar m)

This method is deprecated.
As of Swing version 1.0.3 replaced by setJMenuBar(JMenuBar m).

Sets the menuBar property for this JInternalFrame.

Parameters

m	the `JMenuBar` to use in this internal frame

public void setNormalBounds (Rectangle r)

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.

Parameters

r	the bounds that this internal frame should be restored to

public void setResizable (boolean b)

Sets whether the JInternalFrame can be resized by some user action.

Parameters

b	a boolean, where `true` means this internal frame can be resized

public void setSelected (boolean selected)

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

Throws

PropertyVetoException	when the attempt to set the property is vetoed by the `JInternalFrame`

public void setTitle (String title)

Sets the JInternalFrame title. title may have a null value.

Parameters

title	the `String` to display in the title bar

public void setUI (InternalFrameUI ui)

Sets the UI delegate for this JInternalFrame.

Parameters

ui	the UI delegate

public void show ()

This method is deprecated.
As of JDK version 1.1, replaced by setVisible(boolean).

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 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.

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.

public void updateUI ()

Notification from the UIManager that the look and feel has changed. Replaces the current UI object with the latest version from the UIManager.

Protected Methods

protected void addImpl (Component comp, Object constraints, int index)

Adds the specified child Component. This method is overridden to conditionally forward calls to the contentPane. By default, children are added to the contentPane instead of the frame, refer to RootPaneContainer for details.

Parameters

comp	the component to be enhanced
constraints	the constraints to be respected
index	the index

Throws

IllegalArgumentException	if `index` is invalid
IllegalArgumentException	if adding the container's parent to itself
IllegalArgumentException	if adding a window to a container
