public class DateTime extends Composite
Note that although this class is a subclass of Composite
, it
does not make sense to add children to it, or set a layout on it.
Note: Only one of the styles DATE, TIME, or CALENDAR may be specified, and only one of the styles SHORT, MEDIUM, or LONG may be specified. The DROP_DOWN style is a HINT, and it is only valid with the DATE style.
IMPORTANT: This class is not intended to be subclassed.

public DateTime(Composite parent, int style)
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.

Control
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.

fields of the rectangle are relative to
the receiver's parent (or its display if its parent is null).
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.
