Hi Kevin. I'm glad to see KDE developer here because i'm KDE fan for many years :) But this KDE MIME-support code hardly depend from other KDE stuff, isn't it? I need "pure" Qt code - this is our software client requirement :/ So i'm wrote CMimeDatabase class. And just want to make it fully compliant with freedesktop standart.
(see http://api.kde.org/4.0-api/kdelibs-apidocs/kdecore/html/kmimetype_8h_source.html - KUrl, KServiceType etc.) 2013/12/14 Kevin Krammer <[email protected]> > On Friday, 2013-12-13, 20:11:34, Jerome Leclanche wrote: > > There is a Qt 4 port of this. > > And there should also be the original Qt4 based code in the kdelibs > repository. > > Cheers, > Kevin > > > As for windows support...
