Re: jLabel.setText doesn'
To: comp.lang.java.gui
Hi,
Try as I might I can't seem to get jLabel.setText(line); to output the
messages even though there is a call to System.out.println(line) that
IS working.
You know that you will overwrite all the previous lines which you read
with your reader and only display the last line, right?
Here is my function, it's a little mangled due to me trying lots of
things to get this to work. But I think it makes it's point clear
enough...
I wrote a little window around your code and removed the Progressbar
(just because I only wanted to see the label working). I will insert it
below, it worked for me, but displaying just the last line of "ls". Can
you check if this works for you as well?
If not, I would try to read a file instead of the output of a command
first, just to reduce the complexity as far as possible.
Best luck,
Benjamin
