Unicode Character Chooser
Well, now, by using this component, you can easily add this functionality to your Java applications! For example, here is the demonstrator application showing the kinds of results that you can achieve  And here is the dialog that you use to enter the unicode characters:  The jar file that you download is an executable Jar file that contains, but also demonstrates, the Unicode Chooser. The demonstration is basically a JTextArea wrapped in a JFrame - it shows character insertion into a text component. From your application you could call the UnicodeChooser as follows:
JFrame frame;
JTextArea textArea;
UnicodeChooser chooser = UnicodeChooser.instance(frame);
...
chooser.addPropertyChangeListener(new PropertyChangeListener() {
public void propertyChange(PropertyChangeEvent evt) {
if (UnicodeChooser.INSERT_CHARACTER_PROPERTY.equals(evt.getPropertyName())) {
Character symbol = (Character) evt.getNewValue();
if (symbol != null) {
textArea.insert(symbol.toString(),textArea.getCaretPosition());
}
}
}
});
chooser.setVisible(true);
It's as easy as that! Note that the Unicode Character chooser is modeless, so the user can leave the unicode chooser dialog open while working in a main text component. It also means that you can use the unicode character chooser to input words - or even sentences - of characters rather than just single characters Simon White |
