> ## Static Methods Relevant to DXMEvent Objects

> ###

> andEvent

> Statics Class

> Creates an event that occurs only when the two given events happen simultaneously. The event time for the new event is when both of the given events occur.

> public static DXMEvent andEvent(
> DXMEvent first,
> DXMEvent second
> );

> ##### Parameters

> first and second
>   The DXMEvent objects.

> ##### Return Values

> Returns a DXMEvent object. When the event occurs, it produces a PairObject. The first member is the event data returned by the first event. The second member is the event data returned by the second event.

> ###

> keyDown

> Statics Class

> Returns an DXMEvent when a specific key is pressed. This is a state-transition event.

> public static DXMEvent keyDown(
> int keyCode
> );

> ##### Parameters

> keyCode
>   Can either be quoted characters such as 'a' or specific Java keycode constants.

> ##### Return Values

> Returns the DXMEvent object. This event produces no data.

> ##### Remarks

> The following table lists the hexadecimal values for all the special keycodes. The pattern for each key is 0x10000 plus the Win32 scan code.

> keyUp

> Statics Class

> Returns an DXMEvent when a specific key is released. This is a state-transition event.

> public static DXMEvent keyUp(
> int keyCode
> );

> ##### Parameters

> keyCode
>   Can either be quoted characters such as 'a' or specific Java keycode constants.

> ##### Return Values

> Returns the DXMEvent object. This event produces no data.

> ##### Remarks

> For a list of special keycodes, see keyDown.

> ###

> notEvent

> Statics Class

> Creates an event that occurs when the given event does not occur. This is useful for creating combined events that occur only if the given event is not also occurring, for example, an event that occurs when the left mouse button is down and the right button is not down.

> public static DXMEvent notEvent(
> DXMEvent ev
> );

> ##### Parameters

> ev
>   The DXMEvent object.

> ##### Return Values

> Returns the DXMEvent object. This event produces no data.

> ###

> orEvent

> Statics Class

> Creates an event that occurs when either one of the given events occur. The event time for the new event is when either the first or second given event has occurred.

> public static DXMEvent orEvent(
> DXMEvent first,
> DXMEvent second
> );

> ##### Parameters

> first and second
>   The DXMEvent objects.

> ##### Return Values

> Returns a DXMEvent object. Its data is the event data of either the first or second event.

> ###

> predicate

> Statics Class

> Creates an event that occurs when the value of the given boolean behavior changes from false to true. Note that, because of implementation dependencies and the potential for aliasing, the system cannot always detect when a boolean behavior becomes true. For example, the expression: predicate(eq(sin(localTime), toBvr(0))) may never occur unless the system happens to sample it when sin(localTime)is exactly zero. Therefore, it is advisable to use inequality comparisons (for example, gte) rather than equality comparisons (for example, eq). Alternatively, the timer constructor may be a better choice for these situations.

> public static DXMEvent predicate(
> BooleanBvr bool
> );

> ##### Parameters

> bool
>   The BooleanBvr object.

> ##### Return Values

> Returns the DXMEvent. This event produces no data.

> ###

> thenEvent

> Statics Class

> Creates an event if e2 occurs after e1. The event time of the new event is the time of the second event.

> public static DXMEvent thenEvent(
> DXMEvent e1,
> DXMEvent e2
> );

> ##### Parameters

> e1
>   The first event, that, when it occurs, triggers the second event.
> e2
>   The second event, caused by the occurrence of the first event.

> ##### Return Values

> Returns the DXMEvent object. Its event data is the time the second event fired and a PairObject containing the event data for both events.

> ###

> timer

> Statics Class

> Creates an event that occurs when the specified time has elapsed.

> public static DXMEvent timer(
> NumberBvr timeout
> );

> ##### Parameters

> timeout
>   The NumberBvr object. This parameter can also be of type double.

> ##### Return Values

> Returns the DXMEvent object. This event produces no data.

> ###

> unregisterCallback

> Statics Class

> Used to unregister the callback.

> public static void unregisterCallback(
> Object object
> );

> ##### Parameters

> object
>   The object used to unregister the callback.

> ##### See Also

> registerCallback
