Content Assistant in JAVA

Question

I am trying to create a xml editor which must have a content assistant. I am new in java so my code isn't working properly.

I am trying to change a text color while typing (words between '<' and '>' including '<' and '>' must be blue), my non working code:

textPane.addKeyListener(new KeyAdapter() {
        @Override
        public void keyTyped(KeyEvent arg0) {
            char key = arg0.getKeyChar();
            switch(key){
            case '<': textPane.setForeground(Color.blue); break;
            case '>': textPane.setForeground(Color.black); break;
        }
    }

Thanks

Your approach is not going to work. You need to work with the Document, AttributeSet and DocumentListener classes.

DocumentListener tutorial: http://docs.oracle.com/javase/tutorial/uiswing/events/documentlistener.html

Try doing some reading, and come back with questions about that approach. All you're going to accomplish with your current tack is changing the text color of the entire component, not just the bits between angle brackets.

Is this part of the assignment? It seems a little involved for somebody new to programming.
