How do I change the color of specific words in a JTextPane
just while the user is typing?
Should I override JTextPane
paintComponent
method?
Overwriting paintComponent
will not help you.
This is not an easy one, but not impossible either. Something like this will help you:
DefaultStyledDocument document = new DefaultStyledDocument();
JTextPane textpane = new JTextPane(document);
StyleContext context = new StyleContext();
// build a style
Style style = context.addStyle("test", null);
// set some style properties
StyleConstants.setForeground(style, Color.BLUE);
// add some data to the document
document.insertString(0, "", style);
You may need to tweak this, but at least it shows you where to start.
