  - ### 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`
