```
public void scrollByUnit(int direction)
```
    Scrolls by unit.
    
    Parameters:
    
    direction - the direction
  - scrollDueToClickInTrack
```
protected void scrollDueToClickInTrack(int dir)
```
    This function is called when a mousePressed was detected in the track, not in the thumb. The default behavior is to scroll by block. You can override this method to stop it from scrolling or to add additional behavior.
    
    Parameters:
    
    dir - the direction and number of blocks to scroll
  - xPositionForValue
```
protected int xPositionForValue(int value)
```
    Returns the x position for a value.
    
    Parameters:
    
    value - the value
    
    Returns:
    
    the x position for a value
  - yPositionForValue
```
protected int yPositionForValue(int value)
```
    Returns the y position for a value.
    
    Parameters:
    
    value - the value
    
    Returns:
    
    the y position for a value
  - yPositionForValue
```
protected int yPositionForValue(int value,
                                int trackY,
                                int trackHeight)
```
    Returns the y location for the specified value. No checking is done on the arguments. In particular if trackHeight is negative undefined results may occur.
    
    Parameters:
    
    value - the slider value to get the location for
    
    trackY - y-origin of the track
    
    trackHeight - the height of the track
    
    Returns:
    
    the y location for the specified value of the slider
    
    Since:
    
    1.6
  - valueForYPosition
```
public int valueForYPosition(int yPos)
```
    Returns the value at the y position. If yPos is beyond the track at the bottom or the top, this method sets the value to either the minimum or maximum value of the slider, depending on if the slider is inverted or not.
    
    Parameters:
    
    yPos - the location of the slider along the y axis
    
    Returns:
    
    the value at the y position
  - valueForXPosition
```
public int valueForXPosition(int xPos)
```
    Returns the value at the x position. If xPos is beyond the track at the left or the right, this method sets the value to either the minimum or maximum value of the slider, depending on if the slider is inverted or not.
    
    Parameters:
    
    xPos - the location of the slider along the x axis
    
    Returns:
    
    the value of the x position
