libqxt is licensed under CPL wich allows use in open source as well as in propriarty software.
We don't take part in any holy os,compiler,license war, contrary we believe in cross platform and cross business software.
We support all mayor operating systems and all mayor compilers.
For more information about the CPL please look at the LICENSE file shipped with libqxt.

You can find the sources and the binaries here.
You can also get the bleeding-edge version from our svn repository with this command:

svn co svn://libqxt.org/svn/libqxt/trunk libqxt

The svn version is in development, so some things may not work right at all times.
You might want to stick to the released versions if you need stability.

Configure

make sure qmake is in your PATH and run

./configure

or configure.bat on windows.
see configure --help for more information
(for msvc you could try ./configure.bat -msvc and open the solution file in msvc, we recomend compiling on commandline though)

build

type

make && make install

or nmake , when using msvc
Note: This will also install qxt.prf to your qtdir/mkspecs/features directory.

assistant docs

to get the docs into assistant:
close all running instances of assistant first
then type :

assistant -addContentFile /usr/share/doc/libqxt/index.dcf

or when on windows:

assistant -addContentFile C:\libqxt\doc\libqxt\index.dcf

change the command to match your install path if required

Add the following lines to your project file:

CONFIG  += qxt
        QXT     += core gui

The QXT variable should contain the modules you want. (In this example core and gui are used.)
Note: Some modules depend on other modules. The required modules are added automatically.
if you have an existing msvc project and can't swtich to qmake you can use zbenjamins solution:

             Howto use libqxt in a existing Visual Studio Project:
              1.  create and install libqxt. (See install instructions)
              2.  add {libqxtinstalldir}\include\qxt\QxtCore to your include path
              3.  add {libqxtinstalldir}\lib to your library search path
              4.  to add a specific libqxt module (f.e QxtSql) you have to:
                   - add {libqxtinstalldir}\include\qxt\QxtSql to your include path
                   - add the library QxtSql.lib to your project
                  Most of the times you have also to include the QxtCore and QxtKit modules.
                  It's done the same way like the example above.
        

You should be able to see the documents for libqxt offline in qt assistant ( see install)
