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 contentPane is where you add child components. So, to create a JInternalFrame that has a number of buttons arranged with a BorderLayout object, you might do something like this:

    JComponent c = (JComponent) frame.getContentPane();
    c.setLayout(new BorderLayout());
    c.add(new JButton(), BorderLayout.NORTH);
    c.add(new JButton(), BorderLayout.CENTER);
 

The contentPane is actually managed by an instance of JRootPane, which also manages a layoutPane, glassPane, and optional menuBar for the frame. Please see the JRootPane documentation for a complete description of these components.

For the keyboard keys used by this component in the standard Look and Feel (L&F) renditions, see the JInternalFrame key assignments.

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. A future release of Swing will provide support for long term persistence.

selected - a boolean, where true means the frame is selected (currently active) and false means it is not

Throws:

PropertyVetoException - when the attempt to set the property is vetoed by the receiver.

isSelected

public boolean isSelected()

Returns whether the JInternalFrame is the currently "selected" or active frame.

Returns:

true if the frame is currently selected (active)

See Also:

setSelected(boolean)

setFrameIcon

public void setFrameIcon(Icon icon)

Sets an image to be displayed in the titlebar of the frame (usually in the top-left corner). This image is not the desktopIcon object, which is the image displayed in the JDesktop when the frame is iconified. Passing null to this function is valid, but the L&F can choose the appropriate behavior for that situation, such as displaying no icon or a default icon for the L&F.

Parameters:

icon - the Icon to display in the title bar

See Also:

getFrameIcon()

getFrameIcon

public Icon getFrameIcon()

Returns the image displayed in the title bar of the frame (usually in the top-left corner).

Returns:

the Icon displayed in the title bar

setFrameIcon(javax.swing.Icon)

moveToFront

public void moveToFront()

Convenience method that moves this component to position 0 if its parent is a JLayeredPane.

moveToBack

public void moveToBack()

Convenience method that moves this component to position -1 if its parent is a JLayeredPane.

setLayer

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

See Also:

JLayeredPane

setLayer

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 int specifying this frame's desktop layer

See Also:

setLayer(Integer), JLayeredPane

getLayer

public int getLayer()

Convenience method for getting the layer attribute of this component.

Returns:

an Integer object specifying this frame's desktop layer

See Also:

JLayeredPane

getDesktopPane

public JDesktopPane getDesktopPane()

Convenience method that searchs the anscestor heirarchy for a JDesktop instance. If JInternalFrame finds none, the desktopIcon tree is searched.

Returns:

the JDesktopPane this frame belongs to, or null if none is found

setDesktopIcon

public void setDesktopIcon(JInternalFrame.JDesktopIcon d)

Sets the JDesktopIcon associated with this JInternalFrame.

Parameters:

d - the JDesktopIcon to display on the desktop

Returns:

the JDesktopIcon displayed on the desktop

See Also:

setDesktopIcon(javax.swing.JInternalFrame.JDesktopIcon)

getNormalBounds

public Rectangle getNormalBounds()

If the JInternalFrame is not in maximized state, return getBounds(); otherwise, return the bounds that the JInternalFrame would be restored to.

Returns:

the bounds of this frame when in the normal state

Since:

1.3

setNormalBounds

public void setNormalBounds(Rectangle r)

Sets the normal bounds for this frame, the bounds that the frame would be restored to from its maximized state. This method is intended for use only by desktop managers.

Parameters:

r - the bounds that the frame should be restored to

Since:

1.3

getFocusOwner

public Component getFocusOwner()

If this JInternalFrame is active, return the child which has focus. Otherwise, return null.

At present, this method works only for JComponent children.

Returns:

the component with focus, or null if no children have focus assigned to them.

Since:

1.3

restoreSubcomponentFocus

public void restoreSubcomponentFocus()

This method directs the internal frame to restore focus to the last subcomponent that had focus. This is used by the UI when the user selected the frame, e.g., by clicking on the title bar.

Since:

1.3

reshape

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.

Overrides:

reshape in class JComponent

Parameters:

x - an int giving the component's new horizontal position measured in pixels from the left of its container

y - an int giving the component's new vertical position, measured in pixels from the bottom of its container

width - an int giving the component's new width in pixels

height - an int giving the component's new height in pixels

addInternalFrameListener

public void addInternalFrameListener(InternalFrameListener l)

Adds the specified internal frame listener to receive internal frame events from this internal frame.

Parameters:

l - the internal frame listener

removeInternalFrameListener

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

fireInternalFrameEvent

protected void fireInternalFrameEvent(int id)

doDefaultCloseAction

public void doDefaultCloseAction()

setDefaultCloseOperation

public void setDefaultCloseOperation(int operation)

Sets the operation which will happen by default when the user initiates a "close" on this window. The possible choices are:

• DO_NOTHING_ON_CLOSE - do not do anything - require the program to handle the operation in the windowClosing method of a registered InternalFrameListener object.
• HIDE_ON_CLOSE - automatically hide the window after invoking any registered InternalFrameListener objects
• DISPOSE_ON_CLOSE - automatically hide and dispose the window after invoking any registered InternalFrameListener objects

The value is set to DISPOSE_ON_CLOSE by default.

See Also:

addInternalFrameListener(javax.swing.event.InternalFrameListener), getDefaultCloseOperation()

getDefaultCloseOperation

public int getDefaultCloseOperation()

Returns the default operation which occurs when the user initiates a "close" on this window.

See Also:

setDefaultCloseOperation(int)

pack

public void pack()

Causes subcomponents of this JInternalFrame to be laid out at their preferred size.

See Also:

Window.pack()

show

public void show()

Shows this internal frame, and brings it to the front.

If this window is not yet visible, show makes it visible. If this window is already visible, then this method brings it to the front.

Overrides:

show in class Component

See Also:

Window.show(), Window.toFront(), Component.setVisible(boolean)

dispose

public void dispose()

Disposes of this internal frame. If the frame is not already closed, a frame-closed event is posted.

Gets the warning string that is displayed with this window. Since an internal frame is always secure (since it's fully contained within a window which 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.
