public class Link extends Control
IMPORTANT: This class is not intended to be subclassed.
|Constructor and Description|
Constructs a new instance of this class given its parent and a style value describing its behavior and appearance.

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
Returns the preferred size of the receiver.
Returns the receiver's text, which will be an empty string if it has never been set.
Removes the listener from the collection of listeners who will be notified when the control is selected by the user.

public Link(Composite parent, int style)
The style value is either one of the style constants defined in
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
SWT style constants. The class description
lists the style constants that are applicable to the class.
Style bits are also inherited from superclasses.
parent- a composite control which will be the parent of the new instance (cannot be null)
style- the style of control to construct
public void addSelectionListener(SelectionListener listener)
widgetSelected is called when the control is selected by the user.
widgetDefaultSelected is not called.
listener- the listener which should be notified
public Point computeSize(int wHint, int hHint, boolean changed)
The preferred size of a control is the size that it would
best be displayed at. The width hint and height hint arguments
allow the caller to ask a control questions such as "Given a particular
width, how high does the control need to be to show all of the contents?"
To indicate that the caller does not wish to constrain a particular
dimension, the constant
SWT.DEFAULT is passed for the hint.
If the changed flag is
true, it indicates that the receiver's
contents have changed, therefore any caches that a layout manager
containing the control may have been keeping need to be flushed. When the
control is resized, the changed flag will be
false, so layout
manager caches can be retained.
wHint- the width hint (can be
hHint- the height hint (can be
trueif the control's contents have changed, and
Control.pack(boolean), "computeTrim, getClientArea for controls that implement them"
public String getText()
public void removeSelectionListener(SelectionListener listener)
listener- the listener which should no longer be notified
public void setText(String string)
The string can contain both regular text and hyperlinks. A hyperlink is delimited by an anchor tag, <A> and </A>. Within an anchor, a single HREF attribute is supported. When a hyperlink is selected, the text field of the selection event contains either the text of the hyperlink or the value of its HREF, if one was specified. In the rare case of identical hyperlinks within the same string, the HREF attribute can be used to distinguish between them. The string may include the mnemonic character and line delimiters. The only delimiter the HREF attribute supports is the quotation mark (").
Mnemonics are indicated by an '&' that causes the next character to be the mnemonic. The receiver can have a mnemonic in the text preceding each link. When the user presses a key sequence that matches the mnemonic, focus is assigned to the link that follows the text. Mnemonics in links and in the trailing text are ignored. On most platforms, the mnemonic appears underlined but may be emphasised in a platform specific manner. The mnemonic indicator character '&' can be escaped by doubling it in the string, causing a single '&' to be displayed.
