Field Detail

character

public char character

Enabled: the character represented by the key that was typed. This is the final character that results after all modifiers have been applied. For example, when the user types Ctrl+A, the character value is 0x01 (NUL). It is important that applications do not attempt to modify the character value based on a stateMask (such as SWT.CTRL) or the resulting character will not be correct.

keyCode

public int keyCode

Enabled: the key code of the key that was typed, as defined by the key code constants in class SWT. When the character field of the event is ambiguous, this field contains the unicode value of the original character. For example, typing Ctrl+M or Return both result in the character '\r' but the keyCode field will also contain '\r' when Return was typed.
