public class DateTime extends Composite
Instances of this class are selectable user interface objects that allow the user to enter and modify date or time values.

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

  • Constructor Details

    • DateTime

      public DateTime(Composite parent, int style)
      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 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.

      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

      public void addSelectionListener(SelectionListener listener)
      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 the SelectionListener 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

    • 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 and Canvas 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.

      Overrides:
      checkSubclass in class Composite

      public void setDate(int year, int month, int day)
      Sets the receiver's year, month, and day in a single operation.

      This is the recommended way to set the date, because setting the year, month, and day separately may result in invalid intermediate dates.

      Parameters:

      month - an integer between 0 and 11
      day - a positive integer beginning with 1

      Since:
      3.4

    • setDay

      public void setDay(int day)
      Sets the receiver's date, or day of the month, to the specified day.

      The first day of the month is 1, and the last day depends on the month and year. If the specified day is not valid for the receiver's month and year, then it is ignored.

      Parameters:
      day - a positive integer beginning with 1
      Throws:
      SWTException -
      • ERROR_WIDGET_DISPOSED - if the receiver has been disposed

    • setMenu

      public void setMenu(Menu menu)
      Description copied from class: Control
      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.

      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.

      Overrides:
      setMenu in class Control
      Parameters:
      menu - the new pop up menu
