Class Group
Shadow styles are hints and may not be honoured by the platform. To create a group with the default shadow style for the platform, do not specify a shadow style.
The various SHADOW_* styles are not yet implemented.
- Styles:
- SHADOW_ETCHED_IN, SHADOW_ETCHED_OUT, SHADOW_IN, SHADOW_OUT, SHADOW_NONE
- Events:
- (none)
Note: Only one of the above styles may be specified.
IMPORTANT: This class is not intended to be subclassed.
Note: The styles
SHADOW_XXX are not yet implemented in RWT.- Since:
- 1.0

Constructor Details- 
GroupConstructs 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.The various SHADOW_* styles are not yet implemented. - 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

Method Details- 
setTextSets the receiver's text, which is the string that will be displayed as the receiver's title, to the argument, which may not be null. The string may include the mnemonic character. Mnemonics are indicated by an '&' that causes the next character to be the mnemonic. When the user presses a key sequence that matches the mnemonic, focus is assigned to the first child of the group. On most platforms, the mnemonic appears underlined but may be emphasised in a platform specific manner. The mnemonic indicator character '&' can be escaped by doubling it in the string, causing a single '&' to be displayed.- Parameters:
- text- the new text
- Throws:
- IllegalArgumentException-- ERROR_NULL_ARGUMENT - if the text 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
 
 
- 
getTextReturns the receiver's text, which is the string that the is used as the title. If the text has not previously been set, returns an empty string.- Returns:
- the text
- Throws:
- SWTException-- ERROR_WIDGET_DISPOSED - if the receiver has been disposed
- ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
 
 
- 
getClientAreaDescription copied from class:ScrollableReturns a rectangle which describes the area of the receiver which is capable of displaying data (that is, not covered by the "trimmings").- Overrides:
- getClientAreain class- Scrollable
- Returns:
- the client area
- See Also:
 
- 
computeTrimDescription copied from class:ScrollableGiven a desired client area for the receiver (as described by the arguments), returns the bounding rectangle which would be required to produce that client area.In other words, it returns a rectangle such that, if the receiver's bounds were set to that rectangle, the area of the receiver which is capable of displaying data (that is, not covered by the "trimmings") would be the rectangle described by the arguments (relative to the receiver's parent). - Overrides:
- computeTrimin class- Scrollable
- Parameters:
- x- the desired x coordinate of the client area
- y- the desired y coordinate of the client area
- width- the desired width of the client area
- height- the desired height of the client area
- Returns:
- the required bounds to produce the given client area
- See Also:
 
- 
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)

- 
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.
