Yes, in the makefile you can specify USE_QT4 instead of USE_QT3. It
right now, but it did a few weeks ago. Problem with QT4 is that copying
to widget (bitblt) was so horribly slow. (And I did turn off double
plus some other other options, but it only helped a little bit.)
I don't know what the problem was, maybe my X setup is too old.
It's not surprising that bitblt is a little bit slower in QT4 since
their QPixmap is not a wrapper around the X Pixmap anymore. Maybe
that's the whole explanation. It was usable, but not very nice compared
File requesters and the FX selector are always made with QT4 though.
(IOW. Radium requires both QT3 and QT4 in the default setup.)
