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.
