Styles:
DATE, TIME, CALENDAR, SHORT, MEDIUM, LONG
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.

IMPORTANT: This class is not intended to be subclassed.

Since:
1.1.1

Constructor Detail

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
See Also:
SWT.DATE, SWT.TIME, SWT.CALENDAR, Widget.checkSubclass(), Widget.getStyle()

Overrides:
setFont in class Control
Parameters:
font - the new font (or null)

IllegalArgumentException -
  • ERROR_INVALID_ARGUMENT - if the argument has been disposed
SWTException -
  • ERROR_WIDGET_DISPOSED - if the receiver has been disposed
  • ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver

getAdapter

public 
Object getAdapter(
Class adapter)
Description copied from class: Widget
Implementation of the Adaptable interface.

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:
getAdapter in interface Adaptable
Overrides:
getAdapter in class Composite

computeSize

public 
Point computeSize(int wHint,
                         int hHint,
                         boolean changed)
Description copied from class: Control
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.

Overrides:
computeSize in class Composite

setBounds

public void setBounds(
Rectangle bounds)
Description copied from class: Control
Sets the receiver's size and location to the rectangular area specified by the argument. The x and y 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.

Overrides:
setBounds in class Control
Parameters:
bounds - the new bounds for the receiver

checkSubclass

protected void checkSubclass()
Overrides:
checkSubclass in class Widget
