public class Group extends Composite
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.
Note: Only one of the above styles may be specified.
IMPORTANT: This class is not intended to be subclassed.
SHADOW_XXXare not yet implemented in RWT.
|Constructor and Description|
Constructs a new instance of this class given its parent and a style value describing its behavior and appearance.
|Modifier and Type||Method and Description|
Returns the preferred size of the receiver.
Given 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.
Implementation of the
Returns a rectangle which describes the area of the receiver which is capable of displaying data (that is, not covered by the "trimmings").
Returns the receiver's text, which is the string that the is used as the title.
Sets 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.

public Group(Composite parent, int style)
The style value is either one of the style constants defined in
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
SWT style 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.
parent- a composite control which will be the parent of the new instance (cannot be null)
style- the style of control to construct
public void setText(java.lang.String text)
text- the new text
public java.lang.String getText()
public Rectangle getClientArea()
public Rectangle computeTrim(int x, int y, int width, int height)
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).
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
public Point computeSize(int wHint, int hHint, boolean changed)
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.
wHint- the width hint (can be
hHint- the height hint (can be
trueif the control's contents have changed, and
