1.It can be setted up from current sources (as fork) somewhere on the net.
2.It's not trivial task since Den provided binary libs also for win32,linux32/64 and darwin .
3.Any change must be Qt-4.5 compatibile as we guarantee that, so if your addon does not exist in Qt-4.5 then
it should not be there.
4.Biggest problem is that C bindings (sources) are generated by Den's scripts which aren't available, so everything without
it is real PITA.
1. that would be nice
2. that we should think how to cross compile. may be a problem.
3. I've checked. QFileDialog::sidebarUrls QFileDialog::setSidebarUrls were introduced in Qt 4.3. I am not sure why they were not included.
This also makes me doubt that all Qt sources were generated by scripts. Scripts would get all members of QFileDialog class.
Or, probably, Den just manually removed whatever did not generated correctly.
For example, I had to replace copyPtrIntArrayToQListTemplate call with inline code.
4. Yes, it would be nice Den share these scripts, if he is not interested to maintain these qt*pas bindings.
May be some tools/scripts can be found on Web...
