How do you trap the backspace key in the
keyPressed() event?  I'm trying to only
enable numbers, a period, and a backspace
in a control.

My codes so far looks like:

    char c = e.getKeyChar();


    if ( !Character.isDigit( c )			/* number */
            || ( new Character(c).charValue() != '.' )   /* period */
            ||  ?? )   /* backspace */ )
        e.consume();

TIA.
