Java - live JTextArea append

[Yakisoba]

I have a JTextArea that I would like to have updated as strings are appended to it.

for example, I have this function:

public void updateMessageCenter(String message){
this.outTextArea.append(message + newline);

}


whenever this:

updateMessageCenter("this would be the message");


is called I would like it to display in the text area.

Note: the append works, but it only displays the result AFTER the program has finished executing.

Any suggestions?

I think you're looking for something like a change listener.

I think.

hmmm...

I don't think that is quite what I am looking for.

The append object I use updates the contents of the textarea properly, however it doesn't display line-by-line (only displays when the program is finished running).

What I'm thinking I'll need is to call a paintComponent() on that textarea every time updateMessageCenter is called. Problem is I have a bunch of components on the screen right now and need to determine which ones need to be redrawn and when.

could be completly wrong though...any more suggestions?
