/*!
    \class QGtkStyle
    \brief The QGtkStyle class provides a widget style rendered by GTK+
    \since 4.5

    \internal
    \inmodule QtWidgets

    The QGtkStyle style provides a look and feel that integrates well
    into GTK-based desktop environments such as the XFCe and GNOME.

    It does this by making use of the GTK+ theme engine, ensuring
    that Qt applications look and feel native on these platforms.

    Note: The style requires GTK+ version 2.18 or later.
          The Qt3-based "Qt" GTK+ theme engine will not work with QGtkStyle.
