[RQt-devel] qtinterfaces doc, tutorials, or apps built upon?

[Tomas Sieger]

Hi all,
 could you please point me out some study material, from which to
learn how to use qtinterfaces?
I've already studied qt* vignettes, demos, and also cranvas sources,
but still - the limited qt* doc makes developing quite slow.
Are there any other resources, please?
Or maybe some apps built upon qt*, possibly some that combine qtpaint
painting with qtbase GUI?

regards,
 Tomas
