Method Detail

getOrientation

int getOrientation()
Gets the orientation of the adjustable object.

Returns:
the orientation of the adjustable object; either HORIZONTAL, VERTICAL, or NO_ORIENTATION

setMinimum

void setMinimum(int min)
Sets the minimum value of the adjustable object.

Parameters:
min - the minimum value

getMinimum

int getMinimum()
Gets the minimum value of the adjustable object.

Returns:
the minimum value of the adjustable object

setMaximum

void setMaximum(int max)
Sets the maximum value of the adjustable object.

Parameters:
max - the maximum value

getMaximum

int getMaximum()
Gets the maximum value of the adjustable object.

Returns:
the maximum value of the adjustable object

setUnitIncrement

void setUnitIncrement(int u)
Sets the unit value increment for the adjustable object.

Parameters:
u - the unit increment

getUnitIncrement

int getUnitIncrement()
Gets the unit value increment for the adjustable object.

Returns:
the unit value increment for the adjustable object

setBlockIncrement

void setBlockIncrement(int b)
Sets the block value increment for the adjustable object.

Parameters:
b - the block increment

getBlockIncrement

int getBlockIncrement()
Gets the block value increment for the adjustable object.

Returns:
the block value increment for the adjustable object

setVisibleAmount

void setVisibleAmount(int v)
Sets the length of the proportional indicator of the adjustable object.

Parameters:
v - the length of the indicator

getVisibleAmount

int getVisibleAmount()
Gets the length of the proportional indicator.

Returns:
the length of the proportional indicator

setValue

void setValue(int v)
Sets the current value of the adjustable object. If the value supplied is less than minimum or greater than maximum - visibleAmount, then one of those values is substituted, as appropriate.

Calling this method does not fire an AdjustmentEvent.

Parameters:
v - the current value, between minimum and maximum - visibleAmount

getValue

int getValue()
Gets the current value of the adjustable object.

Returns:
the current value of the adjustable object

addAdjustmentListener

void addAdjustmentListener(AdjustmentListener l)
Adds a listener to receive adjustment events when the value of the adjustable object changes.

Parameters:
l - the listener to receive events
See Also:
AdjustmentEvent

removeAdjustmentListener

void removeAdjustmentListener(AdjustmentListener l)
Removes an adjustment listener.

Parameters:
l - the listener being removed
See Also:
AdjustmentEvent
