Class DateTime
- All Implemented Interfaces:
Drawable
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, CALENDAR_WEEKNUMBERS
- Events:
- DefaultSelection, 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 only valid with the DATE style.
IMPORTANT: This class is not intended to be subclassed.
- Since:
- 3.3

- Restriction:
- This class is not intended to be subclassed by clients.

Constructor Details

DateTime
Constructs 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
SWT
which 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 thoseSWT
style 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

addSelectionListener
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 theSelectionListener
interface.widgetSelected
is called when the user changes the control's value.widgetDefaultSelected
is typically called when ENTER is pressed.- Parameters:
listener
- the listener which should be notified- Throws:
IllegalArgumentException
-- ERROR_NULL_ARGUMENT - if the listener is null
SWTException
-- ERROR_WIDGET_DISPOSED - if the receiver has been disposed
- ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver

checkSubclass
protected void checkSubclass()Description copied from class:Widget
Checks that this class can be subclassed.The SWT class library is intended to be subclassed only at specific, controlled points (most notably,
Composite
andCanvas
when implementing new widgets). This method enforces this rule unless it is overridden.IMPORTANT: 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.
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.
