All Implemented Interfaces:

public class JTabbedPane

extends JComponent

implements java.io.Serializable, SwingConstants

A component that lets the user switch between a group of components by clicking on a tab with a given title and/or icon. For examples and information on using tabbed panes see How to Use Tabbed Panes, a section in The Java Tutorial.

Tabs/components are added to a TabbedPane object by using the addTab and insertTab methods. A tab is represented by an index corresponding to the position it was added in, where the first tab has an index equal to 0 and the last tab has an index equal to the tab count minus 1.

The TabbedPane uses a SingleSelectionModel to represent the set of tab indices and the currently selected index. If the tab count is greater than 0, then there will always be a selected index, which by default will be initialized to the first tab. If the tab count is 0, then the selected index will be -1.

Restrictions

The following restrictions apply to implementations this optional package:

Implementations of AGUI are not required to support the full tooltip functionality as defined in the Java SE Swing user interface toolkit specification and the methods related to tool tips may fail silently as indicated by a system property.. The following methods are used to set and access the tooltip:
• getToolTipTextAt(int)
• setToolTipTextAt(int, java.lang.String)
• Implementations of this class may allow the method JTabbedPane.setMnemonicAt(int,int) to fail silently if this method can not be supported by the platform. The following side effects will occur:
• • The component's label string will not be modified.
  • Attempts to activate the modifier will not be honored.

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 java.beans.XMLEncoder.

Method Detail

paint

public final void paint(java.awt.Graphics g)

Description copied from class: JComponent

Invoked by Swing to draw components. Applications should not invoke paint directly, but should instead use the repaint method to schedule the component for redrawing.

This method actually delegates the work of painting to three protected methods: paintComponent, paintBorder, and paintChildren. They're called in the order listed to ensure that children appear on top of component itself. Generally speaking, the component and its children should not paint in the insets area allocated to the border. Subclasses can just override this method, as always.

Overrides:

paint in class JComponent

Parameters:

g - the Graphics context in which to paint

See Also:

JComponent.paintBorder(java.awt.Graphics), JComponent.paintChildren(java.awt.Graphics), JComponent.getComponentGraphics(java.awt.Graphics), JComponent.repaint(long, int, int, int, int)

createChangeListener

protected ChangeListener createChangeListener()

Subclasses that want to handle ChangeEvents differently can override this to return a subclass of ModelListener or another ChangeListener implementation.

See Also:

fireStateChanged()

addChangeListener

public void addChangeListener(ChangeListener l)

Adds a ChangeListener to this tabbedpane.

Parameters:

l - the ChangeListener to add

See Also:

fireStateChanged(), removeChangeListener(javax.swing.event.ChangeListener)

removeChangeListener

public void removeChangeListener(ChangeListener l)

Removes a ChangeListener from this tabbedpane.

Parameters:

l - the ChangeListener to remove

See Also:

fireStateChanged(), addChangeListener(javax.swing.event.ChangeListener)

getChangeListeners

public ChangeListener[] getChangeListeners()

Returns an array of all the ChangeListeners added to this JTabbedPane with addChangeListener.

Returns:

all of the ChangeListeners added or an empty array if no listeners have been added

Since:

1.4

fireStateChanged

protected void fireStateChanged()

Sends a ChangeEvent, whose source is this tabbedpane, to each listener. This method method is called each time a ChangeEvent is received from the model.

See Also:

addChangeListener(javax.swing.event.ChangeListener), EventListenerList

getModel

public SingleSelectionModel getModel()

Returns the model associated with this tabbedpane.

See Also:

setModel(javax.swing.SingleSelectionModel)

setModel

public void setModel(SingleSelectionModel model)

Sets the model to be used with this tabbedpane.

Parameters:

public int getTabPlacement()

Returns the placement of the tabs for this tabbedpane.

See Also:

setTabPlacement

public void setTabPlacement(int tabPlacement)

Sets the tab placement for this tabbedpane. Possible values are:

• JTabbedPane.TOP
• JTabbedPane.BOTTOM
• JTabbedPane.LEFT
• JTabbedPane.RIGHT

The default value, if not set, is SwingConstants.TOP.

Parameters:

tabPlacement - the placement for the tabs relative to the content

Throws:

java.lang.IllegalArgumentException - if tab placement value isn't one of the above valid values

getTabLayoutPolicy

public int getTabLayoutPolicy()

Returns the policy used by the tabbedpane to layout the tabs when all the tabs will not fit within a single run.

Since:

1.4

See Also:

setTabLayoutPolicy(int)

setTabLayoutPolicy

public void setTabLayoutPolicy(int tabLayoutPolicy)

Sets the policy which the tabbedpane will use in laying out the tabs when all the tabs will not fit within a single run. Possible values are:

• JTabbedPane.WRAP_TAB_LAYOUT
• JTabbedPane.SCROLL_TAB_LAYOUT

The default value, if not set by the UI, is JTabbedPane.WRAP_TAB_LAYOUT.

Some look and feels might only support a subset of the possible layout policies, in which case the value of this property may be ignored.

Parameters:

tabLayoutPolicy - the policy used to layout the tabs

Throws:

java.lang.IllegalArgumentException - if layoutPolicy value isn't one of the above valid values

Since:

1.4

See Also:

getTabLayoutPolicy()

getSelectedIndex

public int getSelectedIndex()

setDisplayedMnemonicIndexAt

public void setDisplayedMnemonicIndexAt(int tabIndex,
                                        int mnemonicIndex)

Provides a hint to the look and feel as to which character in the text should be decorated to represent the mnemonic. Not all look and feels may support this. A value of -1 indicates either there is no mnemonic for this tab, or you do not wish the mnemonic to be displayed for this tab.

The value of this is updated as the properties relating to the mnemonic change (such as the mnemonic itself, the text...). You should only ever have to call this if you do not wish the default character to be underlined. For example, if the text at tab index 3 was 'Apple Price', with a mnemonic of 'p', and you wanted the 'P' to be decorated, as 'Apple Price', you would have to invoke setDisplayedMnemonicIndex(3, 6) after invoking setMnemonicAt(3, KeyEvent.VK_P).

Note that it is the programmer's responsibility to ensure that each tab has a unique mnemonic or unpredictable results may occur.

Parameters:

tabIndex - the index of the tab that the mnemonic refers to

mnemonicIndex - index into the String to underline

Throws:

java.lang.IndexOutOfBoundsException - if tabIndex is out of range (tabIndex < 0 || tabIndex >= tab count)

java.lang.IllegalArgumentException - will be thrown if mnemonicIndex is >= length of the tab title , or < -1

1.4

setMnemonicAt

public void setMnemonicAt(int tabIndex,
                          int mnemonic)

Sets the keyboard mnemonic for accessing the specified tab. The mnemonic is the key which when combined with the look and feel's mouseless modifier (usually Alt) will activate the specified tab.

A mnemonic must correspond to a single key on the keyboard and should be specified using one of the VK_XXX keycodes defined in java.awt.event.KeyEvent. Mnemonics are case-insensitive, therefore a key event with the corresponding keycode would cause the button to be activated whether or not the Shift modifier was pressed.

This will update the displayed mnemonic property for the specified tab.

Parameters:

tabIndex - the index of the tab that the mnemonic refers to

mnemonic - the key code which represents the mnemonic

Throws:

java.lang.IndexOutOfBoundsException - if tabIndex is out of range (tabIndex < 0 || tabIndex >= tab count)

Since:

1.4
