Sets the value of this Scrollbar to the specified value.
Parameters:
value - the new value of the Scrollbar. | | synchronized void | setValues(int value, int visible, int minimum, int maximum)
Sets the values for this Scrollbar.
This method enforces the same constraints as in java.awt.Scrollbar:
- The maximum must be greater than the minimum

and less than or equal to the maximum minus the
visible amount
- The visible amount must be greater than 1 and less than or equal
to the difference between the maximum and minimum values.
| | synchronized void | setValues(int value, int visible, int minimum, int maximum, int unitSize, int blockSize)
Sets param of this Scrollbar to the specified values. | | synchronized void | setVisibleAmount(int newAmount)
Sets the visible amount of this Scrollbar, which is the range
of values represented by the width of the scroll bar's bubble. | | void | startScrolling()
Tell the scroller to start scrolling. | | void | startScrollingInstance()
Tell the instance scroller to start scrolling. | | void | stopScrollingInstance()
Tell the instance scroller to stop scrolling. | | public String | toString()
|

| barWidthbarLength | | int barWidthbarLength(Code) | | |
| widthheight | | int widthheight(Code) | | |
| beforeThumb | | abstract boolean beforeThumb(int x, int y)(Code) | | |
| calculateArrowWidth | | void calculateArrowWidth()(Code) | | |
| calculateThumbRect | | protected Rectangle calculateThumbRect()(Code) | | Method to calculate the scroll thumb's size and position. This is
based on CalcSliderRect in ScrollBar.c of Motif source.
If we ever cache the thumb rect, we'll need to use a clone in
isInThumb().
|
| createArrowShape | | protected Polygon createArrowShape(boolean vertical, boolean up)(Code) | | Creates oriented directed arrow
|
| getArrowAreaWidth | | int getArrowAreaWidth()(Code) | | Width of the area reserved for arrow

|
| getThumbArea | | abstract protected Rectangle getThumbArea()(Code) | | Gets the area of the scroll track
|
| getUnitIncrement | | int getUnitIncrement()(Code) | | Gets the unit increment for this scrollbar.
|
| getVisibleAmount | | int getVisibleAmount()(Code) | | Returns the visible amount of this Scrollbar.
|
| handleMouseEvent | | public void handleMouseEvent(int id, int modifiers, int x, int y)(Code) | |

If we ever cache the thumb rect, we may need to clone the result of
calculateThumbRect().

| setBlockIncrement | | synchronized void setBlockIncrement(int blockSize)(Code) | | Sets the block increment for this scrollbar. This is the value
that will be added (subtracted) when the user hits the block down
(up) gadgets.
Parameters:
blockSize - is the block size for increment or decrement of the value |

| setSize | | public void setSize(int width, int height)(Code) | | |
| setUnitIncrement | | synchronized void setUnitIncrement(int unitSize)(Code) | | Sets the unit increment for this scrollbar. This is the value
that will be added (subtracted) when the user hits the unit down
(up) gadgets.
Parameters:
unitSize - is the unit size for increment or decrement of the value |
| setValue | | synchronized void setValue(int newValue)(Code) | | Sets the value of this Scrollbar to the specified value.
Parameters:
value - the new value of the Scrollbar. If this value isbelow the current minimum or above the current maximum minus the visible amount, it becomes the new one of those values, respectively.
See Also: XScrollbar.getValue |
| setValues | | synchronized void setValues(int value, int visible, int minimum, int maximum)(Code) | | Sets the values for this Scrollbar.
This method enforces the same constraints as in java.awt.Scrollbar:
- The maximum must be greater than the minimum
- The value must be greater than or equal to the minumum
and less than or equal to the maximum minus the
visible amount
- The visible amount must be greater than 1 and less than or equal
to the difference between the maximum and minimum values.
Values which do not meet these criteria are quietly coerced to the
appropriate boundary value.
Parameters:
value - is the position in the current window.
Parameters:
visible - is the amount visible per page
Parameters:
minimum - is the minimum value of the scrollbar
Parameters:
maximum - is the maximum value of the scrollbar |
| setValues | | synchronized void setValues(int value, int visible, int minimum, int maximum, int unitSize, int blockSize)(Code) | | Sets param of this Scrollbar to the specified values.
Parameters:
value - is the position in the current window.
Parameters:
visible - is the amount visible per page
Parameters:
minimum - is the minimum value of the scrollbar
Parameters:
maximum - is the maximum value of the scrollbar
Parameters:
unitSize - is the unit size for increment or decrement of the value
Parameters:
page - is the block size for increment or decrement of the value

| setVisibleAmount | | synchronized void setVisibleAmount(int newAmount)(Code) | | Sets the visible amount of this Scrollbar, which is the range
of values represented by the width of the scroll bar's bubble.
Parameters:
