Class TabFolder

java.lang.Object

org.eclipse.swt.widgets.Widget

org.eclipse.swt.widgets.Control

org.eclipse.swt.widgets.Scrollable

org.eclipse.swt.widgets.Composite

org.eclipse.swt.widgets.TabFolder

All Implemented Interfaces:

Drawable

public class TabFolder
extends Composite

Instances of this class implement the notebook user interface metaphor. It allows the user to select a notebook page from set of pages.

The item children that may be added to instances of this class must be of type TabItem. Control children are created and then set into a tab item using TabItem#setControl.

Note that although this class is a subclass of Composite, it does not make sense to set a layout on it.

Styles:

TOP, BOTTOM

Events:

Selection

Note: Only one of the styles TOP and BOTTOM may be specified.

IMPORTANT: This class is not intended to be subclassed.

Constructor Details

TabFolder

public TabFolder(Composite parent,
 int style)

Constructs a new instance of this class given its parent and a style value describing its behavior and appearance.

The style value is either one of the style constants defined in class SWT which is applicable to instances of this class, or must be built by bitwise OR'ing together (that is, using the int "|" operator) two or more of those SWT style constants. The class description lists the style constants that are applicable to the class. Style bits are also inherited from superclasses.

Parameters:

parent - a composite control which will be the parent of the new instance (cannot be null)

style - the style of control to construct

Throws:

IllegalArgumentException -

• ERROR_NULL_ARGUMENT - if the parent is null

SWTException -

• ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the parent
• ERROR_INVALID_SUBCLASS - if this class is not an allowed subclass

See Also:

• SWT
• SWT.TOP
• SWT.BOTTOM
• Widget.checkSubclass()
• Widget.getStyle()

Method Details

checkStyle

static int checkStyle(int style)

checkSubclass

protected void checkSubclass()

Description copied from class: Widget

Checks that this class can be subclassed.

The SWT class library is intended to be subclassed only at specific, controlled points (most notably, Composite and Canvas when implementing new widgets). This method enforces this rule unless it is overridden.

IMPORTANT: By providing an implementation of this method that allows a subclass of a class which does not normally allow subclassing to be created, the implementer agrees to be fully responsible for the fact that any such subclass will likely fail between SWT releases and will be strongly platform specific. No support is provided for user-written classes which are implemented in this fashion.

The ability to subclass outside of the allowed SWT classes is intended purely to enable those not on the SWT development team to implement patches in order to get around specific limitations in advance of when those limitations can be addressed by the team. Subclassing should not be attempted without an intimate and detailed understanding of the hierarchy.

Overrides:

checkSubclass in class Composite

addSelectionListener

public void addSelectionListener(SelectionListener listener)

Adds the listener to the collection of listeners who will be notified when the user changes the receiver's selection, by sending it one of the messages defined in the SelectionListener interface.

When widgetSelected is called, the item field of the event object is valid. widgetDefaultSelected is not called.

Parameters:

listener - the listener which should be notified when the user changes the receiver's selection

Throws:

IllegalArgumentException -

• ERROR_NULL_ARGUMENT - if the listener is null

SWTException -

• ERROR_WIDGET_DISPOSED - if the receiver has been disposed
• ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver

• ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver

getSelection

public TabItem[] getSelection()

Returns an array of TabItems that are currently selected in the receiver. An empty array indicates that no items are selected.

Note: This is not the actual structure used by the receiver to maintain its selection, so modifying the array will not affect the receiver.

Returns:

an array representing the selection

Throws:

SWTException -

• ERROR_WIDGET_DISPOSED - if the receiver has been disposed
• ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
