Serializable
@Deprecated(since="9") public class Event extends Object implements Serializable
Event
class is obsolete and is available only for backwards compatibility. It has been replaced by the AWTEvent
class and its subclasses. Event
is a platform-independent class that encapsulates events from the platform's Graphical User Interface in the Java 1.0 event model. In Java 1.1 and later versions, the Event
class is maintained only for backwards compatibility. The information in this class description is provided to assist programmers in converting Java 1.0 programs to the new event model.
In the Java 1.0 event model, an event contains an id
field that indicates what type of event it is and which other Event
variables are relevant for the event.
For keyboard events, key
contains a value indicating which key was activated, and modifiers
contains the modifiers for that event. For the KEY_PRESS and KEY_RELEASE event ids, the value of key
is the unicode character code for the key. For KEY_ACTION and KEY_ACTION_RELEASE, the value of key
is one of the defined action-key identifiers in the Event
class (PGUP
, PGDN
, F1
, F2
, etc).

Event
class is obsolete and is available only for backwards compatibility. It has been replaced by the AWTEvent

Event
class is obsolete and is available only for backwards compatibility. It has been replaced by the AWTEvent
class and its subclasses. Creates an instance of Event
with the specified target component, event type, and argument.
target
- the target component.id
- the event type.arg

Event
class is obsolete and is available only for backwards compatibility. It has been replaced by the AWTEvent
class and its subclasses. Translates this event so that its x and y coordinates are increased by dx and dy, respectively.
This method translates an event relative to the given component. This involves, at a minimum, translating the coordinates into the local coordinate system of the given component. It may also involve translating a region in the case of an expose event.
dx
- the distance to translate the x coordinate.dy
- the distance to translate the y coordinate.public boolean shiftDown()
Event
class is obsolete and is available only for backwards compatibility. It has been replaced by the AWTEvent
class and its subclasses. Checks if the Shift key is down.

if the key is down; false
otherwise.public boolean controlDown()
Event
class is obsolete and is available only for backwards compatibility. It has been replaced by the AWTEvent
class and its subclasses. Checks if the Control key is down.
true
if the key is down; false
otherwise.public boolean metaDown()
Event
class is obsolete and is available only for backwards compatibility. It has been replaced by the AWTEvent
class and its subclasses. Checks if the Meta key is down.
true
if the key is down; false
otherwise.protected String paramString()
Event
class is obsolete and is available only for backwards compatibility. It has been replaced by the AWTEvent
class and its subclasses. Returns a string representing the state of this Event
. This method is intended to be used only for debugging purposes, and the content and format of the returned string may vary between implementations. The returned string may be empty but may not be null
.
