Yes, in the makefile you can specify USE_QT4 instead of USE_QT3. It

doesn't work

right now, but it did a few weeks ago. Problem with QT4 is that copying

pixmap

to widget (bitblt) was so horribly slow. (And I did turn off double

buffering

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

to QT3.
File requesters and the FX selector are always made with QT4 though.

:-)

(IOW. Radium requires both QT3 and QT4 in the default setup.)
