Constructor Detail

DefaultBoundedRangeModel

public DefaultBoundedRangeModel(int minimum,
                                int maximum,
                                int initialValue)

Creates a default bounded range model with the given minimum value, maximum value and initial value.

Parameters:

minimum - the minimum value of the model.

maximum - the maximum value of the model.

initialValue - the initial value of the model.

Throws:

java.lang.IllegalArgumentException - if the constraint minimum <= initialValue <= maximum is not satisfied.

Method Detail

getMaximum

public int getMaximum()

Description copied from interface: BoundedRangeModel

Gets the range maximum.

Specified by:

getMaximum in interface BoundedRangeModel

Returns:

the value of the maximum property.

getMinimum

public int getMinimum()

Description copied from interface: BoundedRangeModel

Gets the range minimum.

Specified by:

getMinimum in interface BoundedRangeModel

Returns:

the value of the minimum property.

getValue

public int getValue()

Description copied from interface: BoundedRangeModel

Gets the current value.

Specified by:

getValue in interface BoundedRangeModel

Returns:

the current value.

getPercentComplete

public float getPercentComplete()

Description copied from interface: BoundedRangeModel

Gets the percent complete for the range. Note that this number is between 0.0 and 1.0.

Specified by:

getPercentComplete in interface BoundedRangeModel

Returns:

the percent complete.

setMaximum

public void setMaximum(int maximum)

Description copied from interface: BoundedRangeModel

Sets the range maximum. The other two properties may be changed as well to ensure that minimum <= value <= maximum. Notifies the listener if the model changes.

Specified by:

setMaximum in interface BoundedRangeModel

Parameters:

maximum - the maximum to set.

setMinimum

public void setMinimum(int minimum)

Description copied from interface: BoundedRangeModel

Sets the range minimum. The other two properties may be changed as well to ensure that minimum <= value <= maximum. Notifies the listener if the model changes.

Specified by:

setMinimum in interface BoundedRangeModel

Parameters:

minimum - the minimum to set.

setValue

public void setValue(int value)

Description copied from interface: BoundedRangeModel

Sets the current value. The value may be changed if it does not satisfy the model's constraints. Those constraints are that minimum <= value <= maximum. That means that the value will be bounded to the range [minimum; maximum]. Notifies the listener if the model changes.

Specified by:

setValue in interface BoundedRangeModel

Parameters:

value - the value to set.

addOnValueChangeListener

public void addOnValueChangeListener(OnValueChangeListener onValueChangeListener)

Description copied from interface: BoundedRangeModel

Adds a listener on the value change events of the range.

Specified by:

addOnValueChangeListener in interface BoundedRangeModel

Parameters:

onValueChangeListener - the value listener to add.

removeOnValueChangeListener

public void removeOnValueChangeListener(OnValueChangeListener onValueChangeListener)

Description copied from interface: BoundedRangeModel

Removes a listener on the value change events of the range.

Specified by:

removeOnValueChangeListener in interface BoundedRangeModel

Parameters:

onValueChangeListener - the value listener to remove.
