# 1

[nobr]\n won't work - HTML will. You could use something likeStringBuilder builder = new StringBuilder ();

for (Object element: list) { // or whatever's the type of your list

if (builder.length () > 0) {

builder.append ("<br>");

}

builder.append (String.valueOf (element));

}

label.setText (String.format("<html>%s</html>", builder.toString ());

[/nobr]

would \n work in something else, like a textArea or something (wich i tried but could not draw one in the design cause of nullpointerexeption)

Yes, that'd work fine.
