public class KeyEvent
extends InputEvent

This event is generated when a key is pressed or released. There are two categories of key events:

"Key typed" events are higher-level, and have already compensated for modifiers and keyboard layout to generate a single Unicode character. It may take several key press events to generate one key typed. The getKeyCode method will return VK_UNDEFINED, and getKeyChar will return a valid Unicode character or CHAR_UNDEFINED.

"Key pressed" and "key released" events are lower-level, and are platform and keyboard dependent. They correspond to the actaul motion on a keyboard, and return a virtual key code which labels the key that was pressed. The getKeyCode method will return one of the VK_* constants (except VK_UNDEFINED), and the getKeyChar method is undefined.

Some keys do not generate key typed events, such as the F1 or HELP keys. Not all keyboards can generate all virtual keys, and no attempt is made to simulate the ones that can't be typed. Virtual keys correspond to the keyboard layout, so for example, VK_Q in English is VK_A in French. Also, there are some additional virtual keys to ease handling of actions, such as VK_ALL_CANDIDATES in place of ALT+VK_CONVERT. Do not rely on the value of the VK_* constants, except for VK_ENTER, VK_BACK_SPACE, and VK_TAB.

Initializes a new instance of KeyEvent with the specified information. Note that an invalid id leads to unspecified results.

Parameters:
source - the component that generated this event
id - the event id
when - the timestamp when the even occurred
modifiers - the modifier keys during the event, in old or new style
keyCode - the integer constant for the virtual key type
keyChar - the Unicode value of the key
keyLocation - the location of the key
Throws:
IllegalArgumentException - if source is null, if keyLocation is invalid, or if (id == KEY_TYPED && (keyCode != VK_UNDEFINED || keyChar == CHAR_UNDEFINED))

Initializes a new instance of KeyEvent with the specified information. Note that an invalid id leads to unspecified results.

Parameters:
source - the component that generated this event
id - the event id
when - the timestamp when the even occurred
modifiers - the modifier keys during the event, in old or new style
keyCode - the integer constant for the virtual key type
Throws:
IllegalArgumentException - if source is null, or if id == KEY_TYPED but keyCode != VK_UNDEFINED
Method Detail

getKeyCode

public int getKeyCode()
Returns the key code for the event key. This will be one of the VK_* constants defined in this class. If the event type is KEY_TYPED, the result will be VK_UNDEFINED.

Returns:
the key code for this event

setKeyCode

public void setKeyCode(int keyCode)
Sets the key code for this event. This must be one of the VK_* constants defined in this class.

Parameters:
keyCode - the new key code for this event

getKeyChar

public char getKeyChar()
Returns the Unicode value for the event key. This will be CHAR_UNDEFINED if there is no Unicode equivalent for this key, usually when this is a KEY_PRESSED or KEY_RELEASED event.

Returns:
the Unicode character for this event

setKeyChar

public void setKeyChar(char keyChar)
Sets the Unicode character for this event to the specified value.

Parameters:
keyChar - the new Unicode character for this event

setModifiers

public void setModifiers(int modifiers)
Deprecated. 

Sets the modifier keys to the specified value. This should be a union of the bit mask constants from InputEvent. The use of this method is not recommended, particularly for KEY_TYPED events, which do not check if the modifiers were changed.

Parameters:
modifiers - the new modifier value, in either old or new style
See Also:
InputEvent

getKeyLocation

public int getKeyLocation()
Returns the keyboard location of the key that generated this event. This provides a way to distinguish between keys like left and right shift which share a common key code. The result will be one of KEY_LOCATION_UNKNOWN, KEY_LOCATION_STANDARD, KEY_LOCATION_LEFT, KEY_LOCATION_RIGHT, or KEY_LOCATION_NUMPAD.

Returns:
the key location
Since:
1.4

getKeyText

public static String getKeyText(int keyCode)
Returns the text name of key code, such as "HOME", "F1", or "A". XXX Sun claims this can be localized via the awt.properties file - how do we implement that?

Returns:
the text name of the key code

getKeyModifiersText

public static String getKeyModifiersText(int modifiers)
Returns a string describing the modifiers, such as "Shift" or "Ctrl+Button1". XXX Sun claims this can be localized via the awt.properties file - how do we implement that?

Parameters:
modifiers - the old-style modifiers to convert to text
Returns:
a string representation of the modifiers in this bitmask

isActionKey

public boolean isActionKey()
Tests whether or not this key is an action key. An action key typically does not fire a KEY_TYPED event, and is not a modifier.

Returns:
true if this is an action key

paramString

public String paramString()
Returns a string identifying the event. This is formatted as the field name of the id type, followed by the keyCode, then the keyChar, modifiers (if any), extModifiers (if any), and keyLocation.

Overrides:
paramString in class ComponentEvent
Returns:
a string identifying the event
