Comment 5 for bug 605530

Looks like this is still broken. Judging from the Qt stylesheet reference, the reason text-align doesn't work is that it isn't supported on anything but QProgressBar and QPushButton, which isn't used in any of Mixxx's widgets.

"This property is currently supported only by QPushButton and QProgressBar."

As far as I can tell, there is no way at all to customize the alignment of text in a QLabel via Qt style sheets.
