Class HAdjustmentEvent

java.lang.Object
  java.util.EventObject
      java.awt.AWTEvent
          org.havi.ui.event.HAdjustmentEvent

All Implemented Interfaces:

Serializable

public class HAdjustmentEvent
extends AWTEvent

An HAdjustmentEvent event is used to interact with a component implementing the HAdjustmentValue interface as follows:

• An HAdjustmentEvent event may be sent from the HAVi system to the component to cause a change to the value or editable mode of the component as a result of user interaction. For example, this event may be generated by a virtual keyboard user interface on a platform which lacks suitable adjustment keys.
• An HAdjustmentEvent event is sent from the component to all registered HAdjustmentListeners when a change to the value or editable mode of the component occurs.

All interoperable HAVi components which expect to receive HAdjustmentEvent events should also implement the HAdjustmentInputPreferred interface.

The parameters to the constructors are as follows, in cases where parameters are not used, then the constructor should use the default values.

Default parameter values exposed in the constructors

Field Summary

static int	ADJUST_END_CHANGE An adjustment event with this id indicates that the value of an HAdjustmentValue component has been finally set.
static int	ADJUST_FIRST The first integer id in the range of event ids supported by the HAdjustmentEvent class.
static int	ADJUST_LAST The last integer id in the range of event ids supported by the HAdjustmentEvent class.
static int	ADJUST_LESS An adjustment event with this id is sent whenever the value of an HAdjustmentValue component is decreased by one unit.
static int	ADJUST_MORE An adjustment event with this id is sent whenever the value of an HAdjustmentValue component is increased by one unit.
static int	ADJUST_PAGE_LESS An adjustment event with this id is sent whenever the value of an HAdjustmentValue component is decreased by one block.
static int	ADJUST_PAGE_MORE An adjustment change event with this id is sent whenever the value of an HAdjustmentValue component is increased by one block.
static int	ADJUST_START_CHANGE An adjustment event with this id indicates that the value of an HAdjustmentValue component may be about to change.

Field Detail

ADJUST_FIRST

public static final int ADJUST_FIRST

The first integer id in the range of event ids supported by the HAdjustmentEvent class.

See Also:

Constant Field Values

ADJUST_LAST

public static final int ADJUST_LAST

The last integer id in the range of event ids supported by the HAdjustmentEvent class.

See Also:

Constant Field Values

ADJUST_START_CHANGE

public static final int ADJUST_START_CHANGE

An adjustment event with this id indicates that the value of an HAdjustmentValue component may be about to change. This event is sent when the user causes the component to enter its editable mode. Note that it is a platform specific implementation option for such components to enter editable mode automatically e.g. when they receive input focus. In such a case the order in which the HFocusEvent and HAdjustmentEvent are sent is platform specific.

See Also:

HAdjustmentInputPreferred.getAdjustMode(), Constant Field Values

ADJUST_LESS

public static final int ADJUST_LESS

An adjustment event with this id is sent whenever the value of an HAdjustmentValue component is decreased by one unit.

See Also:

HAdjustmentValue.setUnitIncrement(int), HAdjustmentValue.getUnitIncrement(), Constant Field Values

ADJUST_MORE

public static final int ADJUST_MORE

An adjustment event with this id is sent whenever the value of an HAdjustmentValue component is increased by one unit.

See Also:

HAdjustmentValue.setUnitIncrement(int), HAdjustmentValue.getUnitIncrement(), Constant Field Values

ADJUST_PAGE_LESS

public static final int ADJUST_PAGE_LESS

An adjustment event with this id is sent whenever the value of an HAdjustmentValue component is decreased by one block.

See Also:

HAdjustmentValue.setBlockIncrement(int), HAdjustmentValue.getBlockIncrement(), Constant Field Values

ADJUST_PAGE_MORE

public static final int ADJUST_PAGE_MORE

An adjustment change event with this id is sent whenever the value of an HAdjustmentValue component is increased by one block.

See Also:

HAdjustmentValue.setBlockIncrement(int), HAdjustmentValue.getBlockIncrement(), Constant Field Values

ADJUST_END_CHANGE

public static final int ADJUST_END_CHANGE

An adjustment event with this id indicates that the value of an HAdjustmentValue component has been finally set. This event is sent when the user causes the component to leave its editable mode. Note that it is a platform specific implementation option for such components to leave editable mode automatically e.g. when they lose input focus. In such a case the order in which the HFocusEvent and HAdjustmentEvent are sent is platform specific.

HAdjustmentInputPreferred.getAdjustMode(), Constant Field Values

Constructor Detail

HAdjustmentEvent

public HAdjustmentEvent(HAdjustmentInputPreferred source,
                        int id)

Constructs an HAdjustmentEvent.

Parameters:

source - The HAdjustmentInputPreferred component whose value has been modified.

id - The event id of the HAdjustmentEvent generated by the HAdjustmentInputPreferred component. This is the value that will be returned by the event object's getID method.
