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
