Re: jLabel.setText doesn'

Hi,


You know that you will overwrite all the previous lines which you read
with your reader and only display the last line, right?


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
