this
this(Composite parent, int style)

Constructs a new instance of this class given its parent and a style value describing its behavior and appearance. <p> The style value is either one of the style constants defined in class <code>SWT</code> which is applicable to instances of this class, or must be built by <em>bitwise OR</em>'ing together (that is, using the <code>int</code> "|" operator) two or more of those <code>SWT</code> style constants. The class description lists the style constants that are applicable to the class. Style bits are also inherited from superclasses. </p>

Undocumented in source. Be warned that the author may not have intended to support it.
addControlListener
void addControlListener(ControlListener listener)

Adds the listener to the collection of listeners who will be notified when the control is moved or resized, by sending it one of the messages defined in the <code>ControlListener</code> interface.

addDragDetectListener
void addDragDetectListener(DragDetectListener listener)

Adds the listener to the collection of listeners who will be notified when a drag gesture occurs, by sending it one of the messages defined in the <code>DragDetectListener</code> interface.

addFocusListener
void addFocusListener(FocusListener listener)

Adds the listener to the collection of listeners who will be notified when the control gains or loses focus, by sending it one of the messages defined in the <code>FocusListener</code> interface.

addHelpListener
void addHelpListener(HelpListener listener)

Adds the listener to the collection of listeners who will be notified when help events are generated for the control, by sending it one of the messages defined in the <code>HelpListener</code> interface.

addKeyListener
void addKeyListener(KeyListener listener)

Adds the listener to the collection of listeners who will be notified when keys are pressed and released on the system keyboard, by sending it one of the messages defined in the <code>KeyListener</code> interface. <p> When a key listener is added to a control, the control will take part in widget traversal. By default, all traversal keys (such as the tab key and so on) are delivered to the control. In order for a control to take part in traversal, it should listen for traversal events. Otherwise, the user can traverse into a control but not out. Note that native controls such as table and tree implement key traversal in the operating system. It is not necessary to add traversal listeners for these controls, unless you want to override the default traversal. </p> @param listener the listener which should be notified

To indicate that the caller does not wish to constrain a particular dimension, the constant <code>SWT.DEFAULT</code> is passed for the hint. </p>

computeSize
Point computeSize(int wHint, int hHint, bool changed)

Returns the preferred size of the receiver. <p> The <em>preferred size</em> 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 <code>SWT.DEFAULT</code> is passed for the hint. </p><p> If the changed flag is <code>true</code>, it indicates that the receiver's <em>contents</em> have changed, therefore any caches that a layout manager containing the control may have been keeping need to be flushed.

Sets the receiver's size and location to the rectangular area specified by the argument. The <code>x</code> and <code>y</code> fields of the rectangle are relative to the receiver's parent (or its display if its parent is null). <p> Note: Attempting to set the width or height of the receiver to a negative number will cause that value to be set to zero instead. </p>

setBounds
void setBounds(int x, int y, int width, int height)

Sets the receiver's size and location to the rectangular area specified by the arguments. The <code>x</code> and <code>y</code> arguments are relative to the receiver's parent (or its display if its parent is null), unless the receiver is a shell. In this case, the <code>x</code> and <code>y</code> arguments are relative to the display. <p> Note: Attempting to set the width or height of the receiver to a negative number will cause that value to be set to zero instead. </p>

setBounds
int setBounds(int x, int y, int width, int height, bool move, bool resize)
Undocumented in source. Be warned that the author may not have intended to support it.
setCapture
void setCapture(bool capture)

If the argument is <code>true</code>, causes the receiver to have all mouse events delivered to it until the method is called with <code>false</code> as the argument. Note that on some platforms, a mouse button must currently be down for capture to be assigned.

setCursor
void setCursor(Cursor cursor)

Sets the receiver's cursor to the cursor specified by the argument, or to the default cursor for that kind of control if the argument is null. <p> When the mouse pointer passes over a control its appearance is changed to match the control's cursor. </p>

setDragDetect
void setDragDetect(bool dragDetect)

Sets the receiver's drag detect state. If the argument is <code>true</code>, the receiver will detect drag gestures, otherwise these gestures will be ignored.

setEnabled

setFocus
bool setFocus()

Causes the receiver to have the <em>keyboard focus</em>, such that all keyboard events will be delivered to it. Focus reassignment will respect applicable platform constraints.

setFont
void setFont(Font font)

setLocation
void setLocation(int x, int y)

Sets the receiver's location to the point specified by the arguments which are relative to the receiver's parent (or its display if its parent is null), unless the receiver is a shell. In this case, the point is relative to the display.

setMenu
void setMenu(Menu menu)

Sets the receiver's pop up menu to the argument. All controls may optionally have a pop up menu that is displayed when the user requests one for the control. The sequence of key strokes, button presses and/or button releases that are used to request a pop up menu is platform specific. <p> Note: Disposing of a control that has a pop up menu will dispose of the menu. To avoid this behavior, set the menu to null before the control is disposed. </p>

If the argument is <code>false</code>, causes subsequent drawing operations in the receiver to be ignored. No drawing of any kind can occur in the receiver until the flag is set to true. Graphics operations that occurred while the flag was <code>false</code> are lost. When the flag is set to <code>true</code>, the entire widget is marked as needing to be redrawn. Nested calls to this method are stacked. <p> Note: This operation is a hint and may not be supported on some platforms or for some widgets. </p>

setRegion
void setRegion(Region region)

Sets the shape of the control to the region specified by the argument. When the argument is null, the default shape of the control is restored.

setRelations

The event type is one of the event constants defined in class <code>SWT</code>.

addDisposeListener
void addDisposeListener(DisposeListener listener)

Adds the listener to the collection of listeners who will be notified when the widget is disposed. When the widget is disposed, the listener is notified by sending it the <code>widgetDisposed()</code> message.

checkOpen
void checkOpen()
Undocumented in source. Be warned that the author may not have intended to support it.
checkOrientation
void checkOrientation(Widget parent)
Undocumented in source. Be warned that the author may not have intended to support it.
checkParent
void checkParent(Widget parent)

Throws an exception if the specified widget can not be used as a parent for the receiver.

checkSubclass
void checkSubclass()

Checks that this class can be subclassed. <p> The SWT class library is intended to be subclassed only at specific, controlled points (most notably, <code>Composite</code> and <code>Canvas</code> when implementing new widgets). This method enforces this rule unless it is overridden. </p><p> <em>IMPORTANT:</em> 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. </p><p> 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. </p>

checkWidget
void checkWidget()

Throws an <code>SWTException</code> if the receiver can not be accessed by the caller. This may include both checks on the state of the receiver and more generally on the entire execution context. This method <em>should</em> be called by widget implementors to enforce the standard SWT invariants. <p> Currently, it is an error to invoke any method (other than <code>isDisposed()</code>) on a widget that has had its <code>dispose()</code> method called. It is also an error to call widget methods from any thread that is different from the thread that created the widget. </p><p> In future releases of SWT, there may be more or fewer error checks and exceptions may be thrown for different reasons. </p>

createHandle
void createHandle(int index)
Undocumented in source. Be warned that the author may not have intended to support it.
createWidget

Undocumented in source. Be warned that the author may not have intended to support it.
destroyWidget
void destroyWidget()
Undocumented in source. Be warned that the author may not have intended to support it.
dispose
void dispose()

Disposes of the operating system resources associated with the receiver and all its descendants. After this method has been invoked, the receiver and all descendants will answer <code>true</code> when sent the message <code>isDisposed()</code>. Any internal connections between the widgets in the tree will have been removed to facilitate garbage collection. <p> NOTE: This method is not called recursively on the descendants of the receiver. This means that, widget implementers can not detect when a widget is being disposed of by re-implementing this method, but should instead listen for the <code>Dispose</code> event. </p>

error
void error(int code)
Undocumented in source. Be warned that the author may not have intended to support it.
getData
Object getData()

Returns the application defined widget data associated with the receiver, or null if it has not been set. The <em>widget data</em> is a single, unnamed field that is stored with every widget. <p> Applications may put arbitrary objects in this field. If the object stored in the widget data needs to be notified when the widget is disposed of, it is the application's responsibility to hook the Dispose event on the widget and do so. </p>

getDataStr
String getDataStr()
Undocumented in source. Be warned that the author may not have intended to support it.
getData
Object getData(String key)

Returns the application defined property of the receiver with the specified name, or null if it has not been set. <p> Applications may have associated arbitrary objects with the receiver in this fashion. If the objects stored in the properties need to be notified when the widget is disposed of, it is the application's responsibility to hook the Dispose event on the widget and do so. </p>

getDataStr
String getDataStr(String key)
Undocumented in source. Be warned that the author may not have intended to support it.
getDisplay
Display getDisplay()

Returns the <code>Display</code> that is associated with the receiver. <p> A widget's display is either provided when it is created (for example, top level <code>Shell</code>s) or is the same as its parent's display. </p>

getListeners
Listener[] getListeners(int eventType)

Returns an array of listeners who will be notified when an event of the given type occurs. The event type is one of the event constants defined in class <code>SWT</code>.

getName
String getName()
Undocumented in source. Be warned that the author may not have intended to support it.
getNameText
String getNameText()
Undocumented in source. Be warned that the author may not have intended to support it.
getStyle
int getStyle()

Returns the receiver's style information. <p> Note that the value which is returned by this method <em>may not match</em> the value which was provided to the constructor when the receiver was created. This can occur when the underlying operating system does not support a particular combination of requested styles. For example, if the platform widget used to implement a particular SWT widget always has scroll bars, the result of calling this method would always have the <code>SWT.H_SCROLL</code> and <code>SWT.V_SCROLL</code> bits set. </p>
