  It's inspired by trackers, but has fewer

 The development of Radium started in 1999 on the Amiga platform.   Since then
  it has been ported to Linux. 
 Any plans to move to at least Qt4? Qt3 is so 2000s :) 
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.)
