Class DateTime
 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.
 
- Styles:
- DATE, TIME, CALENDAR, SHORT, MEDIUM, LONG, DROP_DOWN
- Events:
- Selection
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.

- 1.1.1

Constructor Details- 
DateTimeConstructs 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 SWTwhich is applicable to instances of this class, or must be built by bitwise OR'ing together (that is, using theint"|" operator) two or more of thoseSWTstyle 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:
- IllegalArgumentException-- ERROR_NULL_ARGUMENT - if the parent is null
 
- 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

setFontDescription copied from class:ControlSets the font that the receiver will use to paint textual information to the font specified by the argument, or to the default font for that kind of control if the argument is null.
- 
getAdapterDescription copied from class:WidgetImplementation of theAdaptableinterface.IMPORTANT: This method is not part of the RWT public API. It is marked public only so that it can be shared within the packages provided by RWT. It should never be accessed from application code. - Specified by:
- getAdapterin interface- Adaptable
- Overrides:
- getAdapterin class- Composite
- Parameters:
- adapter- the lookup class
- Returns:
- an object that can be cast to the given class or nullif there is no adapter associated with the given class.
 
- 
computeSizeDescription copied from class:ControlReturns 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.DEFAULTis 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 befalse, so layout manager caches can be retained.- Overrides:
- computeSizein class- Composite
- Parameters:
- wHint- the width hint (can be- SWT.DEFAULT)
- hHint- the height hint (can be- SWT.DEFAULT)
- changed-- trueif the control's contents have changed, and- falseotherwise
- Returns:
- the preferred size of the control.
- See Also:
- 
- Layout
- Control.getBorderWidth()
- Control.getBounds()
- Control.getSize()
- Control.pack(boolean)
- "computeTrim, getClientArea for controls that implement them"
 
 
- 
setBoundsDescription copied from class:ControlSets the receiver's size and location to the rectangular area specified by the argument. Thexandyfields 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.
