I tried this
Code:
1 24 "style.xml"
but it didn't work. However, this does work and gives this output.
Code:
1 RT_MANIFEST "style.xml"
Updating Progress Bar-result-jpg

Though there is a bit of 'lag' when the progress bar finishes, and you click cancel. I also notice that this progress bar is faster than the one without a style. Is that just a side effect?
