public abstract class Scrollable extends Control
IMPORTANT: This class is intended to be subclassed only within the SWT implementation.
| Constructor and Description |
|---|
Scrollable(Composite parent,
int style)
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 |
|---|---|
Rectangle |
computeTrim(int x,
int y,
int width,
int height)
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.
|
Rectangle |
getClientArea()
Returns a rectangle which describes the area of the
receiver which is capable of displaying data (that is,
not covered by the "trimmings").
|
ScrollBar |
getHorizontalBar()
Returns the receiver's horizontal scroll bar if it has
one, and null if it does not.
|
ScrollBar |
getVerticalBar()
Returns the receiver's vertical scroll bar if it has
one, and null if it does not.

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.

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).
