Class ScrollPane
- Accessible, ImageObserver, MenuContainer, Serializable
This widget provides a scrollable region that allows a single
subcomponent to be viewed through a smaller window.
static int | SCROLLBARS_ALWAYS- Constant indicating that scrollbars are always displayed in this
window.
|
static int | SCROLLBARS_AS_NEEDED- Constant indicating that scrollbars are created as needed in this
windows.
|
static int | SCROLLBARS_NEVER- Constant indicating that scrollbars are never displayed in this window.
|
ScrollPane()- Initializes a new instance of
ScrollPane with a default
scrollbar policy of SCROLLBARS_AS_NEEDED.

SCROLLBARS_ALWAYS
public static final int SCROLLBARS_ALWAYS
Constant indicating that scrollbars are always displayed in this
window.
SCROLLBARS_AS_NEEDED
public static final int SCROLLBARS_AS_NEEDED
Constant indicating that scrollbars are created as needed in this
windows.
SCROLLBARS_NEVER
public static final int SCROLLBARS_NEVER
Constant indicating that scrollbars are never displayed in this window.
ScrollPane
public ScrollPane()
Initializes a new instance of ScrollPane with a default
scrollbar policy of SCROLLBARS_AS_NEEDED.
ScrollPane
public ScrollPane(int scrollbarDisplayPolicy)
Initializes a new instance of ScrollPane with the
specified scrollbar policy.
scrollbarDisplayPolicy - When to display scrollbars, which must
be one of the constants defined in this class.
addImpl
protected final void addImpl(Component component,
Object constraints,
int index) Adds the specified child component to this container. A
ScrollPane can have at most one child, so if a second
one is added, then first one is removed.
- addImpl in interface Container
component - The component to add to this container.constraints - A list of layout constraints for this object.index - The index at which to add the child, which is ignored
in this implementation.
doLayout
public void doLayout()
Lays out this component. This consists of resizing the sole child
component to its perferred size.
- doLayout in interface Container
eventTypeEnabled
protected boolean eventTypeEnabled(int type)
Tells whether or not an event is enabled.
getHAdjustable
public Adjustable getHAdjustable()
Returns the horizontal scrollbar for this object. If the scrollbar
display policy is set to SCROLLBARS_NEVER then this
will be null.
- The horizontal scrollbar for this window.
getHScrollbarHeight
public int getHScrollbarHeight()
Returns the height of a horizontal scrollbar.
- The height of a horizontal scrollbar.
getScrollPosition
public Point getScrollPosition()
Returns the current scroll position of the viewport.
- The current scroll position of the viewport.
getScrollbarDisplayPolicy
public int getScrollbarDisplayPolicy()
Returns the current scrollbar display policy.
- The current scrollbar display policy.
getVAdjustable
public Adjustable getVAdjustable()
Returns the vertical scrollbar for this object. If the scrollbar
display policy is set to SCROLLBARS_NEVER then this
will be null.
- The horizontal scrollbar for this window.
getVScrollbarWidth
public int getVScrollbarWidth()
Returns the width of a vertical scrollbar.
- The width of a vertical scrollbar.
getViewportSize
public Dimension getViewportSize()
Returns the current viewport size. The viewport is the region of
this object's window where the child is actually displayed.
layout
public void layout()
This method is deprecated in favor of
doLayout().
Lays out this component. This consists of resizing the sole child
component to its perferred size.
- layout in interface Container
setLayout
public final void setLayout(LayoutManager layoutManager)
This method overrides its superclass method to ensure no layout
manager is set for this container. ScrollPane's do
not have layout managers.
- setLayout in interface Container
setScrollPosition
public void setScrollPosition(int x,
int y) Sets the scroll position to the specified value.
x - The new X coordinate of the scroll position.y - The new Y coordinate of the scroll position.
