}

Constructs a KeyEvent object.

This method throws an IllegalArgumentException if source is null.

Parameters:

source - The Component that originated the event

id - An integer indicating the type of event. For information on allowable values, see the class description for KeyEvent

when - A long integer that specifies the time the event occurred. Passing negative or zero value is not recommended

modifiers - The modifier keys down during event (shift, ctrl, alt, meta). Passing negative value is not recommended. Zero value means that no modifiers were passed. Use either an extended _DOWN_MASK or old _MASK modifiers, however do not mix models in the one event. The extended modifiers are preferred for using

keyCode - The integer code for an actual key, or VK_UNDEFINED (for a key-typed event)

keyChar - The Unicode character generated by this event, or CHAR_UNDEFINED (for key-pressed and key-released events which do not map to a valid Unicode character)

Throws:

IllegalArgumentException - if id is KEY_TYPED and keyChar is CHAR_UNDEFINED; or if id is KEY_TYPED and keyCode is not VK_UNDEFINED

IllegalArgumentException - if source is null

Constructs a KeyEvent object.

This method throws an IllegalArgumentException if source is null.

Parameters:

source - The Component that originated the event

id - An integer indicating the type of event. For information on allowable values, see the class description for KeyEvent

when - A long integer that specifies the time the event occurred. Passing negative or zero value is not recommended

modifiers - The modifier keys down during event (shift, ctrl, alt, meta). Passing negative value is not recommended. Zero value means that no modifiers were passed. Use either an extended _DOWN_MASK or old _MASK modifiers, however do not mix models in the one event. The extended modifiers are preferred for using

keyCode - The integer code for an actual key, or VK_UNDEFINED (for a key-typed event)

keyChar - The Unicode character generated by this event, or CHAR_UNDEFINED (for key-pressed and key-released events which do not map to a valid Unicode character)

keyLocation - Identifies the key location. The only legal values are KEY_LOCATION_UNKNOWN, KEY_LOCATION_STANDARD, KEY_LOCATION_LEFT, KEY_LOCATION_RIGHT, and KEY_LOCATION_NUMPAD.

Throws:

IllegalArgumentException - if id is KEY_TYPED and keyChar is CHAR_UNDEFINED; or if id is KEY_TYPED and keyCode is not VK_UNDEFINED; or if id is KEY_TYPED and keyLocation is not KEY_LOCATION_UNKNOWN; or if keyLocation is not one of the legal values enumerated above.

IllegalArgumentException - if source is null

 public int getExtendedKeyCode() 
{
        return (int)extendedKeyCode;
}

Returns an extended key code for the event. The extended key code is a unique id assigned to a key on the keyboard just like {@code keyCode}. However, unlike {@code keyCode}, this value depends on the current keyboard layout. For instance, pressing the left topmost letter key in a common English layout produces the same value as {@code keyCode}, {@code VK_Q}. Pressing the same key in a regular Russian layout gives another code, unique for the letter "Cyrillic I short".

 public static int getExtendedKeyCodeForChar(int c) 
{
        // Return a keycode (if any) associated with a character.
        return sun.awt.ExtendedKeyCodes.getExtendedKeyCodeForChar(c);
}

Returns an extended key code for a unicode character.

 public char getKeyChar() 
{
        return keyChar;
}

Returns the character associated with the key in this event. For example, the KEY_TYPED event for shift + "a" returns the value for "A".

KEY_PRESSED and KEY_RELEASED events are not intended for reporting of character input. Therefore, the values returned by this method are guaranteed to be meaningful only for KEY_TYPED events.

 public int getKeyCode() 
{
        return keyCode;
}

Returns the integer keyCode associated with the key in this event.

 public int getKeyLocation() 
{
        return keyLocation;
}

Returns the location of the key that originated this key event. Some keys occur more than once on a keyboard, e.g. the left and right shift keys. Additionally, some keys occur on the numeric keypad. This provides a way of distinguishing such keys.

 public static String getKeyModifiersText(int modifiers) 
{
        StringBuilder buf = new StringBuilder();
        if ((modifiers & InputEvent.META_MASK) != 0) {
            buf.append(Toolkit.getProperty("AWT.meta", "Meta"));
            buf.append("+");
        }
        if ((modifiers & InputEvent.CTRL_MASK) != 0) {
            buf.append(Toolkit.getProperty("AWT.control", "Ctrl"));
            buf.append("+");
        }
        if ((modifiers & InputEvent.ALT_MASK) != 0) {
            buf.append(Toolkit.getProperty("AWT.alt", "Alt"));
            buf.append("+");
        }
        if ((modifiers & InputEvent.SHIFT_MASK) != 0) {
            buf.append(Toolkit.getProperty("AWT.shift", "Shift"));
            buf.append("+");
        }
        if ((modifiers & InputEvent.ALT_GRAPH_MASK) != 0) {
            buf.append(Toolkit.getProperty("AWT.altGraph", "Alt Graph"));
            buf.append("+");
        }
        if ((modifiers & InputEvent.BUTTON1_MASK) != 0) {
            buf.append(Toolkit.getProperty("AWT.button1", "Button1"));
            buf.append("+");
        }
        if (buf.length()  > 0) {
            buf.setLength(buf.length()-1); // remove trailing '+'
        }
        return buf.toString();
}

Returns a String describing the modifier key(s), such as "Shift", or "Ctrl+Shift". These strings can be localized by changing the awt.properties file.

Note that InputEvent.ALT_MASK and InputEvent.BUTTON2_MASK have the same value, so the string "Alt" is returned for both modifiers. Likewise, InputEvent.META_MASK and InputEvent.BUTTON3_MASK have the same value, so the string "Meta" is returned for both modifiers.

Returns a String describing the keyCode, such as "HOME", "F1" or "A". These strings can be localized by changing the awt.properties file.

Returns whether the key in this event is an "action" key. Typically an action key does not fire a unicode character and is not a modifier key.

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

 public  void setKeyChar(char keyChar) 
{
        this.keyChar = keyChar;
}

Set the keyChar value to indicate a logical character.

 public  void setKeyCode(int keyCode) 
{
        this.keyCode = keyCode;
}

Set the keyCode value to indicate a physical key.

 public  void setModifiers(int modifiers) 
{
        this.modifiers = modifiers;
        if ((getModifiers() != 0) && (getModifiersEx() == 0)) {
            setNewModifiers();
        } else if ((getModifiers() == 0) && (getModifiersEx() != 0)) {
            setOldModifiers();
        }
}

Set the modifiers to indicate additional keys that were held down (e.g. shift, ctrl, alt, meta) defined as part of InputEvent.

NOTE: use of this method is not recommended, because many AWT implementations do not recognize modifier changes. This is especially true for KEY_TYPED events where the shift modifier is changed.
