Constructor Details

TransliteratingTextComponent

public TransliteratingTextComponent()

Constructor.

Method Details

handleKeyTyped

protected void handleKeyTyped(KeyEvent e)

DumbTextComponent API. Framework method that is called when a KeyEvent is received. This implementation runs the new character through the current Transliterator, if one is set, and inserts the transliterated text into the buffer.

Overrides:

handleKeyTyped in class DumbTextComponent

flush

public void flush()

transliterate

protected void transliterate(char ch,
 boolean flush)

setTransliterator

public void setTransliterator(Transliterator t)

Set the Transliterator and direction to use to process incoming KeyEvents.

Parameters:

t - the Transliterator to use

getTransliterator

public Transliterator getTransliterator()

escape

public static final String escape(String s)

Escape non-ASCII characters as Unicode. JUST FOR DEBUGGING OUTPUT.
