The listener 0N/A * is therefore spared the details of processing individual mouse movements 0N/A * and mouse clicks, and can instead process a "meaningful" (semantic) 0N/A * event like "button pressed". 217N/A * An unspecified behavior will be caused if the {@code id} parameter 217N/A * of any particular {@code ActionEvent} instance is not 217N/A * in the range from {@code ACTION_FIRST} to {@code ACTION_LAST}. 0N/A * @see ActionListener 0N/A * @author Carl Quinn 0N/A * The shift modifier. An indicator that the shift key was held 0N/A * down during the event. 0N/A * The control modifier. An indicator that the control key was held 0N/A * down during the event. 0N/A * The meta modifier. An indicator that the meta key was held 0N/A * down during the event. 0N/A * The alt modifier. An indicator that the alt key was held 0N/A * down during the event. 0N/A * The first number in the range of ids used for action events. 0N/A * The last number in the range of ids used for action events. 0N/A * This event id indicates that a meaningful action occured. 0N/A * The nonlocalized string that gives more details 0N/A * of what actually caused the event. 0N/A * This information is very specific to the component 0N/A * @see #getActionCommand 0N/A * Timestamp of when this event occurred. Because an ActionEvent is a high- 0N/A * level, semantic event, the timestamp is typically the same as an 0N/A * underlying InputEvent. 0N/A * This represents the key modifier that was selected, 0N/A * and is used to determine the state of the selected key. 0N/A * If no modifier has been selected it will default to 0N/A * @see #getModifiers 0N/A * JDK 1.1 serialVersionUID 0N/A * Constructs an <code>ActionEvent</code> object. 217N/A * This method throws an 0N/A * <code>IllegalArgumentException</code> if <code>source</code> 0N/A * is <code>null</code>. 0N/A * A <code>null</code> <code>command</code> string is legal, 0N/A * but not recommended. 217N/A * @param source The object that originated the event 217N/A * @param id An integer that identifies the event. 217N/A * For information on allowable values, see 217N/A * the class description for {@link ActionEvent} 217N/A * @param command A string that may specify a command (possibly one 0N/A * of several) associated with the event 0N/A * @throws IllegalArgumentException if <code>source</code> is null 217N/A * @see #getActionCommand() 0N/A * Constructs an <code>ActionEvent</code> object with modifier keys. 217N/A * This method throws an 0N/A * <code>IllegalArgumentException</code> if <code>source</code> 0N/A * is <code>null</code>. 0N/A * A <code>null</code> <code>command</code> string is legal, 0N/A * but not recommended. 217N/A * @param source The object that originated the event 217N/A * @param id An integer that identifies the event. 217N/A * For information on allowable values, see 217N/A * the class description for {@link ActionEvent} 217N/A * @param command A string that may specify a command (possibly one 217N/A * of several) associated with the event 217N/A * @param modifiers The modifier keys down during event 217N/A * (shift, ctrl, alt, meta). 217N/A * Passing negative parameter is not recommended. 217N/A * Zero value means that no modifiers were passed 0N/A * @throws IllegalArgumentException if <code>source</code> is null 217N/A * @see #getActionCommand() 0N/A * Constructs an <code>ActionEvent</code> object with the specified 0N/A * modifier keys and timestamp. 217N/A * This method throws an 0N/A * <code>IllegalArgumentException</code> if <code>source</code> 0N/A * is <code>null</code>. 0N/A * A <code>null</code> <code>command</code> string is legal, 0N/A * but not recommended. 217N/A * @param source The object that originated the event 217N/A * @param id An integer that identifies the event. 217N/A * For information on allowable values, see 217N/A * the class description for {@link ActionEvent} 217N/A * @param command A string that may specify a command (possibly one 217N/A * of several) associated with the event 217N/A * @param modifiers The modifier keys down during event 217N/A * (shift, ctrl, alt, meta). 217N/A * Passing negative parameter is not recommended. 217N/A * Zero value means that no modifiers were passed 217N/A * @param when A long that gives the time the event occurred. 217N/A * Passing negative or zero value 0N/A * @throws IllegalArgumentException if <code>source</code> is null 217N/A * @see #getActionCommand() 0N/A * Returns the command string associated with this action. 0N/A * This string allows a "modal" component to specify one of several 0N/A * commands, depending on its state.
