From kde-cygwin Fri Sep 24 08:39:27 2004 From: Holger Schroeder Date: Fri, 24 Sep 2004 08:39:27 +0000 To: kde-cygwin Subject: Re: License and copyright iussues (was: qwindowxpstyle.cpp) Message-Id: <200409241039.27076.holger-kde () holgis ! net> X-MARC-Message: https://marc.info/?l=kde-cygwin&m=109601518018862 Hi, first: IANAL. i started this native port of qt native on win32, and i did it the following way: i started with the X11 GPL version of qt. in that version all files were dual-licensed in the headers. as i only had the right to use qt under the gpl license, i used it under the gpl license. i mainly took the *_x11.cpp files in there and copied them over to *_win.cpp and replaced the X11 function calls by native win32 GDI and whatever function calls. when doing that, i removed the lines from the original headers, which stated, that the files could be used under the qt commercial license. imagine the following case: a commercial customer from TT has only the right to use the X11 version. and now he finds our work and would read, that he can use it with a commercial Qt license. so we would give him the possibility to create commercial windows programs with qt. this is surely not what we want. as i understand it, we should recheck, that all files, that we created/changed donīt have the lines in the header, that state, that the file can be used with a commercial qt license. as we always worked on the files under the gpl license, we can not grant any license rights on the files, besides the gpl. if there are any files in cvs, from which it isnīt clear, that they are not simply copied over from a commercial qt-windows version, we have to remove them from cvs. btw: you are doing great work on this project right now, lyx people consider using this qt version, the kdiff3 guy is testing it, the KO/Pi guy tests it, and even Jaroslaw Staniek from the Kexi project tests it to create the windows version of Kexi with it, once he completes the merge of his kdelibs changes for windows in main kde cvs. you rock !!! thanks, Holger On Friday 24 September 2004 09:59, Chris January wrote: > Andreas raises a valid point about this file. > If this is an original file written by someone outside of Trolltech and you > wish to license it to kde-cygwin under the GPL license then can the > original author please re-submit the file with an appropriate copyright > notice (including their name) and license terms.
