class, or must be built by bitwise OR'ing together
(that is, using the int "|" operator) two or more
of those SWT style constants. |

| addKeyListener | | public void addKeyListener(KeyListener listener)(Code) | | 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 KeyListener
interface.
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.
Parameters:
listener - the listener which should be notified
exception:
IllegalArgumentException - - ERROR_NULL_ARGUMENT - if the listener is null
exception:
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 Point computeSize(int wHint, int hHint)(Code) | | Returns the preferred size of the receiver.
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.
Parameters:
wHint - the width hint (can be SWT.DEFAULT)
Parameters:
hHint - the height hint (can be SWT.DEFAULT) the preferred size of the control
exception:
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 Point computeSize(int wHint, int hHint, boolean changed)(Code) | | Returns the preferred size of the receiver.
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.
Parameters:
wHint - the width hint (can be SWT.DEFAULT)
Parameters:
hHint - the height hint (can be SWT.DEFAULT)
Parameters:
changed - true if the control's contents have changed, and false otherwise the preferred size of the control.

| dragDetect | | public boolean dragDetect(Event event)(Code) | | Detects a drag and drop gesture. This method is used
to detect a drag gesture when called from within a mouse
down listener.
By default, a drag is detected when the gesture
occurs anywhere within the client area of a control.
Some controls, such as tables and trees, override this
behavior. In addition to the operating system specific
drag gesture, they require the mouse to be inside an
item. Custom widget writers can use setDragDetect
to disable the default detection, listen for mouse down,
and then call dragDetect() from within the
listener to conditionally detect a drag.
Parameters:
event - the mouse down event true if the gesture occurred, and false otherwise.
exception:
IllegalArgumentException - - ERROR_NULL_ARGUMENT when the event is null

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.
Parameters:
changed - whether or not the receiver's contents have changed

The next time a paint request is processed, that area of
the receiver will be painted, including the background.
If the all flag is true, any
children of the receiver which intersect with the specified
area will also paint their intersecting areas. If the
all flag is false, the children
will not be painted.
Parameters:
x - the x coordinate of the area to draw
Parameters:
y - the y coordinate of the area to draw
Parameters:
width - the width of the area to draw
Parameters:
height - the height of the area to draw
