flush contents of JTextArea

Thread view:

trpost@gmail.com - 21 Jul 2006 22:20 GMT

I am using JTextArea to write the status of several URL's, there are
about 100 of them. I am writting the output to the JTextArea and
stdout. When I run through the loop (takes about 60 seconds) to get the
status, I see the results are instantly printed to stdout, but have to
wait for the execution to end before I see anything in the JTextArea.

I am writing to stdout using System.out.println("....") and writing to
JTextArea using textArea1.append("....")

Is there anything I can do to flush the results instantly to the
JTextArea like is done with System.out.println or are there any
inherent flush methods for a JTextArea?

Thanks

I would bet that you're writing the results to your text area within the
EDT. It's busy doing your work instead of updating the screen. Put your
job into a thread and post updates back to the EDT.

Thanks... Logically this makes sense, but I have not done much with
threads... I may need to read up a bit, but if you could provide a
quick example or reference, I would appreciate it.

Show us some actual code. I've done a lot of what you describe and
never had too much delay. It will never be as fast as System.out.
