| | public void | setExtent(int value)
| | public void | setMaximum(int maximum)

| BLOCK | | final public static int BLOCK(Code) | | |
| MARGIN | | final public static int MARGIN(Code) | | |
| UNIT | | final public static int UNIT(Code) | | |
| changeFromEvent | | protected boolean changeFromEvent(Code) | | |
| SAbstractAdjustable | | public SAbstractAdjustable(int value, int extent, int min, int max)(Code) | | Creates a scrollbar with the specified orientation,
value, extent, mimimum, and maximum.
The "extent" is the size of the viewable area. It is also known
as the "visible amount".
Note: Use setBlockIncrement to set the block
increment to a size slightly smaller than the view's extent.
That way, when the user jumps the knob to an adjacent position,
one or two lines of the original contents remain in view.
throws:
IllegalArgumentException - if orientation is not one of VERTICAL, HORIZONTAL

See Also: SAbstractAdjustable.setVisibleAmount
See Also: SAbstractAdjustable.setMinimum
See Also: SAbstractAdjustable.setMaximum |
| SAbstractAdjustable | | public SAbstractAdjustable()(Code) | | Creates a scrollbar with the specified orientation
and the following initial values:
minimum = 0
maximum = 100
value = 0
extent = 10
|
| addAdjustmentListener | | public void addAdjustmentListener(AdjustmentListener l)(Code) | | Adds an AdjustmentListener. Adjustment listeners are notified
each time the scrollbar's model changes. Adjustment events are
provided for backwards compatability with java.awt.Scrollbar.
Note that the AdjustmentEvents type property will always have a
placeholder value of AdjustmentEvent.TRACK because all changes
to a BoundedRangeModels value are considered equivalent. To change
the value of a BoundedRangeModel one just sets its value property,
i.e. model.setValue(123). No information about the origin of the
change, e.g. it's a block decrement, is provided. We don't try
fabricate the origin of the change here.
Parameters:
l - the AdjustmentLister to add

| adjust | | abstract protected void adjust()(Code) | | |
| fireAdjustmentValueChanged | | protected void fireAdjustmentValueChanged(int id, int type, int value)(Code) | | |
| fireFinalEvents | | public void fireFinalEvents()(Code) | | |
| fireIntermediateEvents | | public void fireIntermediateEvents()(Code) | | |
| getBlockIncrement | | public int getBlockIncrement(int direction)(Code) | | Returns the amount to change the scrollbar's value by,
given a block (usually "page") up/down request. A ScrollBarUI
implementation typically calls this method when the user clicks
above or below the scrollbar "knob" to change the value
up or down by large amount. Subclasses my override this
method to compute a value, e.g. the change required to scroll
up or down one paragraph in a text document.
The JScrollPane component creates scrollbars (by default)
that override this method and delegate to the viewports
Scrollable view, if it has one. The Scrollable interface
provides a more specialized version of this method.
Parameters:
direction - is -1 or 1 for up/down respectively the value of the blockIncrement property
See Also: SAbstractAdjustable.setBlockIncrement
See Also: SAbstractAdjustable.setValue |
| getExtent | | final public int getExtent()(Code) | | |
| getMaximum | | final public int getMaximum()(Code) | | The maximum value of the scrollbar is maximum - extent.
the value of the model's maximum property
See Also: SAbstractAdjustable.setMaximum |
| getMinimum | | final public int getMinimum()(Code) | | Returns the minimum value supported by the scrollbar
(usually zero).
the value of the model's minimum property
See Also: SAbstractAdjustable.setMinimum |
| getUnitIncrement | | public int getUnitIncrement(int direction)(Code) | | Returns the amount to change the scrollbar's value by,
given a unit up/down request. A ScrollBarUI implementation
typically calls this method when the user clicks on a scrollbar
up/down arrow and uses the result to update the scrollbar's
value. Subclasses my override this method to compute
a value, e.g. the change required to scroll up or down one
(variable height) line text or one row in a table.
The JScrollPane component creates scrollbars (by default)
that override this method and delegate to the viewports
Scrollable view, if it has one. The Scrollable interface
provides a more specialized version of this method.
Parameters:
direction - is -1 or 1 for up/down respectively the value of the unitIncrement property
See Also: SAbstractAdjustable.setUnitIncrement
See Also: SAbstractAdjustable.setValue |
| getVisibleAmount | | final public int getVisibleAmount()(Code) | | Returns the scrollbar's extent, aka its "visibleAmount". In many
scrollbar look and feel implementations the size of the
scrollbar "knob" or "thumb" is proportional to the extent.
the value of the model's extent property
See Also: SAbstractAdjustable.setVisibleAmount |
| isChangeFromEvent | | public boolean isChangeFromEvent()(Code) | | |
| processLowLevelEvent | | public void processLowLevelEvent(String action, String[] values)(Code) | | |
| setExtent | | public void setExtent(int value)(Code) | | |
| setValueIsAdjusting | | public void setValueIsAdjusting(boolean b)(Code) | | Sets the model's valueIsAdjusting property. Scrollbar look and
feel implementations should set this property to true when
a knob drag begins, and to false when the drag ends. The
scrollbar model will not generate ChangeEvents while
valueIsAdjusting is true. True if the scrollbar thumb is being dragged.
