Deklaration

public class KeyEvent
extends java.awt.event.InputEvent

Beschreibung

Diese Klasse repräsentiert ein Key-Event. Sie werden beim Drücken oder Loslassen einer Taste ausgelöst. KeyEvent definiert zahlreiche Konstanten (»Virtual Keys«), die zur plattformunabhängigen Abfrage der gedrückten Taste verwendet werden können.

Konstruktoren im Detail

public KeyEvent(Component source, int id, long when, int modifiers, int keyCode)
Erzeugt ein neues KeyEvent.
public KeyEvent(Component source, int id, long when, int modifiers, int keyCode, char keyChar)
Erzeugt ein neues KeyEvent mit dem Auslöser source, dem Typ id und dem Eintrittszeitpunkt when. Die Taste wird durch den virtuellen Code keyCode und die in modifiers gesetzten Zusatztasten beschrieben. Falls es sich um ein Unicode-Zeichen handelt, ist es in keyChar enthalten, ansonsten hat keyChar den Wert CHAR_UNDEFINED.

 

Methoden im Detail

public char getKeyChar()
Liefert das Unicode-Zeichen der Taste. Falls es sich um eine Sondertaste handelt, ist der Rückgabewert CHAR_UNDEFINED.
public int getKeyCode()
Liefert den virtuellen Code der Taste. Bei KEY_TYPED-Events ist der Rückgabewert VK_UNDEFINED.
public int getKeyLocation()     [1.4]
Liefert die Position der Taste (z.B. linke oder rechte »Shift«-Taste.
public static String getKeyModifiersText(int modifiers)     [1.2]
Liefert einen Text, der die in modifiers gesetzten Modifier-Tasten enthält.
public static String getKeyText(int keyCode)
Liefert den Namen der Taste. Mit dieser Methode können insbesondere die Namen der Sondertasten ermittelt werden.
public boolean isActionKey()
Liefert true, falls es sich um eine Aktionstaste handelt, sonst false.
public String paramString()
Liefert einen String, der den Ereignis-Typ und den Namen der Taste enthält.
public void setKeyChar(char keyChar)
Setzt das Unicode-Zeichen des Ereignisses auf keyChar.
public void setKeyCode(int keyCode)
Setzt den virtuellen Tastencode des Ereignisses auf keyCode.
public void setModifiers(int modifiers)     [1.2]
Setzt die Modifier-Tasten des Events mit der Bitmaske modifiers.
