getBlockIncrement(): Gets the block value increment for the adjustable object.
getMaximum(): Gets the maximum value of the adjustable object.
getMinimum(): Gets the minimum value of the adjustable object.
getOrientation(): Gets the orientation of the adjustable object.
getUnitIncrement(): Gets the unit value increment for the adjustable object.
getValue(): Gets the current value of the adjustable object.
getVisibleAmount(): Gets the length of the propertional indicator.
removeAdjustmentListener(AdjustmentListener): Removes an adjustment listener.
setBlockIncrement(int): Sets the block value increment for the adjustable object.
setMaximum(int): Sets the maximum value of the adjustable object.
setMinimum(int): Sets the minimum value of the adjustable object.
setUnitIncrement(int): Sets the unit value increment for the adjustable object.
setValue(int): Sets the current value of the adjustable object.
setVisibleAmount(int): Sets the length of the proportionl indicator of the adjustable object.
