- Gets the height of the tick area for horizontal sliders and the width of the
tick area for vertical sliders. BasicSliderUI uses the returned value to
determine the tick area rectangle. If you want to give your ticks some room,
make this larger than you need and paint your ticks away from the sides in paintTicks().

- Called for every label in the label table. Used to draw the labels for horizontal sliders.
The graphics have been translated to labelRect.y already.
- See Also:
JSlider.setLabelTable(java.util.Dictionary)
paintVerticalLabel
protected void paintVerticalLabel(Graphics g,
int value,
Component label)
- Called for every label in the label table. Used to draw the labels for vertical sliders.
The graphics have been translated to labelRect.x already.

scrollByBlock
public void scrollByBlock(int direction)
scrollByUnit
public void scrollByUnit(int 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.
xPositionForValue
protected int xPositionForValue(int value)
yPositionForValue
protected int yPositionForValue(int value)
valueForYPosition
public int valueForYPosition(int yPos)
- Returns a value give a y position. If yPos is past the track at the top or the
bottom it will set the value to the min or max of the slider, depending if the
slider is inverted or not.
valueForXPosition
public int valueForXPosition(int xPos)
- Returns a value give an x position. If xPos is past the track at the left or the
right it will set the value to the min or max of the slider, depending if the
slider is inverted or not.
