Question

So I have a socket connected and constantly reading from a server. I have no problem printing lines to the terminal as they arrive, but I’m struggling with Swing. I want to add each line to the display as it comes in, with certain pre-defined words highlighted. I looked at JEditPane, and the only way I could see would be setText(getText()+newText), which I looked at and thought it looked very wrong. I had a look at the Document classes, and none of them seems to have an obvious append method. Am I missing something obvious, or is there an easy way to do this with another component?

Answer 1

One way to address this would be to create a JTextPane with a DocumentListener that will do your necessary hightlight.
Create your text as you get from server and call insertString on the text pane’s document. The insertString would work as append.

Check the javadoc out.
