JInternalFrame (Java 2 Platform SE 5.0) (original) (raw)

javax.swing

Class JInternalFrame

java.lang.Object extended by java.awt.Component java.awt.Container javax.swing.JComponent javax.swing.JInternalFrame

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 theDesktopManager object maintained by the JDesktopPane.

The JInternalFrame content pane is where you add child components. As a conveniance add and its variants, remove andsetLayout have been overridden to forward to thecontentPane 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 ofJRootPane, which also manages a layout pane, glass pane, and optional menu bar for the internal frame. Please see theJRootPane documentation for a complete description of these components. Refer to RootPaneContainer for details on adding, removing and setting the LayoutManager of a JInternalFrame.

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

setSelected

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.

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](../../java/awt/Component.html#show%28%29) in class [Component](../../java/awt/Component.html "class in java.awt")

hide

public void hide()

Overrides:

[hide](../../java/awt/Component.html#hide%28%29) in class [Component](../../java/awt/Component.html "class in java.awt")

dispose

public void dispose()

Makes this internal frame invisible, unselected, and closed. If the frame is not already closed, this method fires anINTERNAL_FRAME_CLOSED event. The results of invoking this method are similar tosetClosed(true), but dispose always succeeds in closing the internal frame and does not fire an INTERNAL_FRAME_CLOSING event.

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](../../java/awt/Container.html#setFocusCycleRoot%28boolean%29) in class [Container](../../java/awt/Container.html "class in java.awt")

Parameters:

focusCycleRoot - this value is ignored

Since:

1.4

isFocusCycleRoot

public final boolean isFocusCycleRoot()

Always returns true because all JInternalFrames must be roots of a focus traversal cycle.

Overrides:

[isFocusCycleRoot](../../java/awt/Container.html#isFocusCycleRoot%28%29) in class [Container](../../java/awt/Container.html "class in java.awt")

Returns:

true

Since:

1.4

getFocusCycleRootAncestor

public final Container getFocusCycleRootAncestor()

Always returns null because JInternalFrames must always be roots of a focus traversal cycle.

Overrides:

[getFocusCycleRootAncestor](../../java/awt/Component.html#getFocusCycleRootAncestor%28%29) in class [Component](../../java/awt/Component.html "class in java.awt")

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](../../javax/swing/JComponent.html#paramString%28%29) in class [JComponent](../../javax/swing/JComponent.html "class in javax.swing")

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](../../javax/swing/JComponent.html#paintComponent%28java.awt.Graphics%29) in class [JComponent](../../javax/swing/JComponent.html "class in javax.swing")

Parameters:

g - the Graphics object to protect

getAccessibleContext

public AccessibleContext getAccessibleContext()

Gets the AccessibleContext associated with thisJInternalFrame. For internal frames, the AccessibleContext takes the form of an AccessibleJInternalFrame object. A new AccessibleJInternalFrame instance is created if necessary.

Specified by:

[getAccessibleContext](../../javax/accessibility/Accessible.html#getAccessibleContext%28%29) in interface [Accessible](../../javax/accessibility/Accessible.html "interface in javax.accessibility")

Overrides:

[getAccessibleContext](../../javax/swing/JComponent.html#getAccessibleContext%28%29) in class [JComponent](../../javax/swing/JComponent.html "class in javax.swing")

Returns:

an AccessibleJInternalFrame that serves as the AccessibleContext of thisJInternalFrame
