  - getProperty
```
public static String getProperty(JComponent jc,

                                 String defaultValue)
```
    This retrieves a property. If the component has this property manually set (by calling component.putClientProperty()), then that value will be returned. Otherwise this method refers to UIManager.get(). If that value is missing, this returns defaultValue.
    
    Parameters:
    
    jc - component
    
    propertyName - the property name
    
    defaultValue - if no other value is found, this is returned
    
    Returns:
    
    the property value
  - getClickLocationTolerance
```
public abstract int getClickLocationTolerance()
```
    How many pixels can you deviate from a thumb and and still "click" it
    
    Returns:
    
    click location tolerance
  - validatePositions
```
protected static boolean validatePositions(MultiThumbSliderUI.State state)
```
    Makes sure the thumbs are in the right order.
    
    Parameters:
    
    state - state
    
    Returns:
    
    true if the thumbs are valid. False if there are two thumbs with the same value (this is not allowed)
  - addThumb
```
protected boolean addThumb(int index1,
                           int index2)
```
    This will try to add a thumb between index1 and index2.
    This method will not add a thumb if there is already a very small distance between these two endpoints
    
    Parameters:
    
    index1 - index 1
    
    index2 - index 2
    
    Returns:
    
    true if a new thumb was added
  - updateIndication

```
  - calculateGeometry
```
protected void calculateGeometry()
