Field Detail

scrolledHandle

long scrolledHandle

---

horizontalBar

ScrollBar horizontalBar

---

verticalBar

ScrollBar verticalBar

Constructor Detail

Scrollable

Scrollable()

Prevents uninitialized instances from being created outside the package.

---

Scrollable

public Scrollable(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.

Method Detail

clientHandle

long clientHandle()

---

computeTrim

public org.eclipse.swt.graphics.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.

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).
