Static Methods Relevant to DXMEvent Objects
Statics Class
andEventCreates 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.
Statics Class
keyDownReturns 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.
Key KeyCode PGUP 10021 PGDN 10022 END 10023 HOME 10024 LEFT 10025 UP 10026 RIGHT 10027 DOWN 10028 INSERT 1002D DELETE 1002E NUMPAD0 10060 NUMPAD1 10061 NUMPAD2 10062 NUMPAD3 10063 NUMPAD4 10064 NUMPAD5 10065 NUMPAD6 10066 NUMPAD7 10067 NUMPAD8 10068 NUMPAD9 10069 MULTIPLY 1006A ADD 1006B SEPARATOR 1006C SUBTRACT 1006D DECIMAL 1006E DIVIDE 1006F F1 10070 F2 10071 F3 10072 F4 10073 F5 10074 F6 10075 F7 10076 F8 10077 F9 10078 F10 10079 F11 1007A F12 1007B F13 1007C F14 1007D F15 1007E F16 1007F F17 10080 F18 10081 F19 10082 F20 10083 F21 10084 F22 10085 F23 10086 F24 10087 Statics Class
keyUpReturns 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.
Statics Class
notEventCreates 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.
Statics Class
orEventCreates 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.
Statics Class
predicateCreates 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.
Statics Class
thenEventCreates 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.
Statics Class
timerCreates 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.
Statics Class
unregisterCallbackUsed to unregister the callback.
public static void unregisterCallback(
Object object
);Parameters
- object
- The object used to unregister the callback.
