org.eclipse.swt.widgets.Widget
   org.eclipse.swt.widgets.Control
      org.eclipse.swt.widgets.Scrollable

All known Subclasses:   org.eclipse.swt.widgets.List,  org.eclipse.swt.widgets.Text,  org.eclipse.swt.widgets.Composite,
Scrollable
abstract public class Scrollable extends Control (Code)
This class is the abstract superclass of all classes which represent controls that have standard scroll bars.
Styles:
H_SCROLL, V_SCROLL
Events:
(none)

IMPORTANT: This class is intended to be subclassed only within the SWT implementation.



Field Summary
 ScrollBarhorizontalBarverticalBar
    

Constructor Summary
 Scrollable()
     Prevents uninitialized instances from being created outside the package.
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.


Method Summary
public  RectanglecomputeTrim(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.
 ScrollBarcreateScrollBar(int type)
    
protected  voidcreateWidget()
    
public  RectanglegetClientArea()
     Returns a rectangle which describes the area of the receiver which is capable of displaying data (that is, not covered by the "trimmings").
public  ScrollBargetHorizontalBar()
     Returns the receiver's horizontal scroll bar if it has one, and null if it does not.
public  ScrollBargetVerticalBar()
     Returns the receiver's vertical scroll bar if it has one, and null if it does not.

Constructor Detail
Scrollable
Scrollable()(Code)
Prevents uninitialized instances from being created outside the package.


Scrollable
public Scrollable(Composite parent, int style)(Code)
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)
Parameters:
  style - the style of control to construct
exception:
  IllegalArgumentException -
  • ERROR_NULL_ARGUMENT - if the parent is null

exception:
  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.H_SCROLL
See Also:   SWT.V_SCROLL
See Also:   Widget.checkSubclass
See Also:   Widget.getStyle



Method Detail
computeTrim
public Rectangle computeTrim(int x, int y, int width, int height)(Code)
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).


Parameters:
  x - the desired x coordinate of the client area
Parameters:
  y - the desired y coordinate of the client area
Parameters:
  width - the desired width of the client area
Parameters:
  height - the desired height of the client area the required bounds to produce the given client area
exception:
  SWTException -
  • ERROR_WIDGET_DISPOSED - if the receiver has been disposed
  • ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver

See Also:   Scrollable.getClientArea

getClientArea
public Rectangle getClientArea()(Code)
Returns a rectangle which describes the area of the receiver which is capable of displaying data (that is, not covered by the "trimmings"). the client area
exception:
  SWTException -
  • ERROR_WIDGET_DISPOSED - if the receiver has been disposed
  • ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver

See Also:   Scrollable.computeTrim


getHorizontalBar
public ScrollBar getHorizontalBar()(Code)
Returns the receiver's horizontal scroll bar if it has one, and null if it does not. the horizontal scroll bar (or null)
exception:
  SWTException -
  • ERROR_WIDGET_DISPOSED - if the receiver has been disposed
  • ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver


getVerticalBar
public ScrollBar getVerticalBar()(Code)
Returns the receiver's vertical scroll bar if it has one, and null if it does not. the vertical scroll bar (or null)
exception:
  SWTException -
  • ERROR_WIDGET_DISPOSED - if the receiver has been disposed
  • ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
