DESCRIPTION
       The QStyleOption class specifies optional parameters for QStyle functions.

       Some QStyle functions take an optional argument specifying extra information that is
       required for a paritical primitive or control. So that the QStyle class can be extended,
       QStyleOption is used to provide a variable-argument for these options.

       The QStyleOption class has constructors for each type of optional argument, and this set
       of constructors may be extended in future Qt releases. There are also corresponding access
       functions that return the optional arguments: these too may be extended.

       For each constructor, you should refer to the documentation of the QStyle functions to see
       the meaning of the arguments.

       When calling QStyle functions from your own widgets, you must only pass the default
       QStyleOption or the argument that QStyle is documented to accept. For example, if the
       function expects QStyleOption(QMenuItem *, int), passing QStyleOption(QMenuItem *) leaves
       the optional integer argument uninitialized.

       When subclassing QStyle, you must similarly only expect the default or documented
       arguments. The other arguments will have uninitialized values.

       If you make your own QStyle subclasses and your own widgets, you can make a subclass of
       QStyleOption to pass additional arguments to your QStyle subclass. You will need to cast
       the "const QStyleOption&" argument to your subclass, so be sure your style has been called
       from your widget.

       See also Widget Appearance and Style.
