Constructor Detail

NebulaSlider

public NebulaSlider(org.eclipse.swt.widgets.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:

java.lang.IllegalArgumentException -

• ERROR_NULL_ARGUMENT - if the parent is null

org.eclipse.swt.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

Widget.getStyle()

Method Detail

addListener

public void addListener(int eventType,
                        org.eclipse.swt.widgets.Listener listener)

Overrides:

addListener in class org.eclipse.swt.widgets.Widget

See Also:

Widget.addListener(int, org.eclipse.swt.widgets.Listener)

addSelectionListener

public void addSelectionListener(org.eclipse.swt.events.SelectionListener listener)

Adds the listener to the collection of listeners who will be notified when the control is selected by the user, by sending it one of the messages defined in the SelectionListener interface.

widgetDefaultSelected is not called.

Parameters:

listener - the listener which should be notified when the control is selected by the user,

Throws:

java.lang.IllegalArgumentException -

• ERROR_NULL_ARGUMENT - if the listener is null

org.eclipse.swt.SWTException -

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

computeSize

public org.eclipse.swt.graphics.Point computeSize(int wHint,
                                                  int hHint,
                                                  boolean changed)

Overrides:

computeSize in class org.eclipse.swt.widgets.Control

See Also:

Control.computeSize(int, int, boolean)

removeSelectionListener

public void removeSelectionListener(org.eclipse.swt.events.SelectionListener listener)

Removes the listener from the collection of listeners who will be notified when the control is selected by the user.

Parameters:

listener - the listener which should no longer be notified
