Parameters:
e - an event object containing the following fields:
  • [out] value - the number that is the current value of this object

setCurrentValue

public void setCurrentValue(AccessibleValueEvent e)
Sets the value of this object to the given number. The argument is clipped to the valid interval whose upper and lower bounds are returned by getMaximumValue and getMinimumValue, i.e. if it is lower than the minimum value the new value will be the minimum, and if it is greater than the maximum then the new value will be the maximum.

Specified by:
setCurrentValue in interface AccessibleValueListener
Parameters:
e - an event object containing the following fields:
  • [in/out] value - on input, the number that will be the new value of this object
    - on output, set to null if the value cannot be set

getMaximumValue

public void getMaximumValue(AccessibleValueEvent e)
Returns the maximum value that can be represented by this object.

Specified by:
getMaximumValue in interface AccessibleValueListener
Parameters:
e - an event object containing the following fields:
  • [out] value - the number that is the maximum value that this object can represent. If this object has no upper bound then null is returned.

getMinimumValue

public void getMinimumValue(AccessibleValueEvent e)
Returns the minimum value that can be represented by this object.

Specified by:
getMinimumValue in interface AccessibleValueListener
Parameters:
