Method Detail

getKey

public Key getKey()

Returns the key code key that was pressed or released.

The key code corresponds to the actual key on the keyboard, rather than the generated character.

All three types of key events provide this information.

getModifiers

public java.util.EnumSet<KeyboardModifier> getModifiers()

Returns keyboard modifiers.

The result is a logical OR of KeyboardModifier flags.

getCharCode

public int getCharCode()

Returns the unicode character code.

This is only defined for a keyPressed event, and returns the unicode character code of a character that is entered.

For the keyWentDown and keyWentUp events, '0' is returned.

The getCharCode() may be different from getKey(). For example, a Key_M key may correspond to 'm' or 'M' character, depending on whether the shift key is pressed simultaneously.

getKey(), getText()

getText

public java.lang.String getText()

The (unicode) text that this key generated.

This is only defined for a keyPressed event, and returns a string that holds exactly one unicode character, which corresponds to getCharCode().

For the keyWentDown and keyWentUp events, an empty string is returned.
