jdk.awt.event.ActionEvent — clojure-interop/java.awt 1.0.5

A semantic event which indicates that a component-defined action occurred. This high-level event is generated by a component (such as a Button) when the component-specific action occurs (such as being pressed). The event is passed to every ActionListener object that registered to receive such events using the component's addActionListener method.

Note: To invoke an ActionEvent on a Button using the keyboard, use the Space bar.

The object that implements the ActionListener interface gets this ActionEvent when the event occurs. The listener is therefore spared the details of processing individual mouse movements and mouse clicks, and can instead process a "meaningful" (semantic) event like "button pressed".

An unspecified behavior will be caused if the id parameter of any particular ActionEvent instance is not in the range from ACTION_FIRST to ACTION_LAST.

*-action-first clj

Static Constant.

The first number in the range of ids used for action events.

type: int

*-action-last clj

Static Constant.

The last number in the range of ids used for action events.

type: int

*-action-performed clj

Static Constant.

This event id indicates that a meaningful action occurred.

type: int

*-alt-mask clj

Static Constant.

The alt modifier. An indicator that the alt key was held down during the event.

type: int

*-ctrl-mask clj

Static Constant.

The control modifier. An indicator that the control key was held down during the event.

type: int

*-meta-mask clj

Static Constant.

The meta modifier. An indicator that the meta key was held down during the event.

type: int

*-shift-mask clj

Static Constant.

The shift modifier. An indicator that the shift key was held down during the event.

type: int

->action-event clj

(->action-event source id command)

(->action-event source id command modifiers)

(->action-event source id command when modifiers)

Constructor.

Constructs an ActionEvent object with the specified modifier keys and timestamp.

This method throws an IllegalArgumentException if source is null. A null command string is legal, but not recommended.

source - The object that originated the event - java.lang.Object id - An integer that identifies the event. For information on allowable values, see the class description for ActionEvent - int command - A string that may specify a command (possibly one of several) associated with the event - java.lang.String when - A long that gives the time the event occurred. Passing negative or zero value is not recommended - long modifiers - The modifier keys down during event (shift, ctrl, alt, meta). Passing negative parameter is not recommended. Zero value means that no modifiers were passed - int

throws: java.lang.IllegalArgumentException - if source is null

get-action-command clj

(get-action-command this)

Returns the command string associated with this action. This string allows a "modal" component to specify one of several commands, depending on its state. For example, a single button might toggle between "show details" and "hide details". The source object and the event would be the same in each case, but the command string would identify the intended action.

Note that if a null command string was passed to the constructor for this ActionEvent, this this method returns null.

returns: the string identifying the command for this event - java.lang.String

get-modifiers clj

(get-modifiers this)

Returns the modifier keys held down during this action event.

returns: the bitwise-or of the modifier constants - int

get-when clj

(get-when this)

Returns the timestamp of when this event occurred. Because an ActionEvent is a high-level, semantic event, the timestamp is typically the same as an underlying InputEvent.

returns: this event's timestamp - long

param-string clj

(param-string this)

Returns a parameter string identifying this action event. This method is useful for event-logging and for debugging.

returns: a string identifying the event and its associated command - java.lang.String
