# Qt X11 Extras

Qt X11 Extras enables the Qt programmer to write applications for the Linux/X11 platform. Applications developed with Qt can also be deployed across several other desktop and embedded operating systems without having to rewrite the source code.

## Getting Started

      #include <QX11Info>

To link against the module, add this line to your qmake `.pro` file:

      QT += x11extras
