After I sent my note I realized that this probably belonged in a specialized 
widget library rather than being part of the core Qt library.  So I agree 
with you.   Bob's follow up note where he suggests that things like color 
selection widgets should be color managed is probably something that the Qt 
core should handle at least as an option.

LProf is being ported to Qt4 right now and it is only days away from having 
the Qt4 branch merged into the main line.  But we still need to remove the 
Qt3 compatibility widgets at this point and this is something that we will be 
doing gradually as we go forward after the Qt4 branch is merged.  All of the 
UI code is using designer 4 at this point and as soon as the port specific 
regressions are fixed it will be merged.

I am all in favor of having a common Qt CM widgets library and I don't think 
this needs to be part of the core Qt widget set.    We really should have a 
common widget set if for no other reason than that it would make the UI of 
the various Qt projects more consistant.  In fact it might make sense to 
create a subproject for this that is hosted by the LProf project.  That would 
put the library in a logical place where is was easy to find and highly 
visible.  But there might be other alternatives as well.

I addition there might be other CM specific widgets that could be included in 
a library like this such as a widget for viewing a 3D gamut hull and/or for 
comparing the gamut hulls of two profiles.

The same sort of thing needs to happen in the Gtk realm as well.
