<hr><a name="details"></a><h2>Detailed Description</h2>
The QStyleOption class specifies optional parameters for <a href="qstyle.html">QStyle</a> functions.
<p> 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 use to
give a variable-argument for these options.
<p> 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.
<p> For each constructor, you should refer to the documentation of
the QStyle functions to see the meaning of the arguments.
<p> When calling QStyle functions from your own widgets, you must only
pass either 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.
<p> When subclassing <a href="qstyle.html">QStyle</a>, you must similarly only expect the default
or documented arguments. The other arguments will have uninitialized
values.
<p> 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.
<p>See also <a href="appearance.html">Widget Appearance and Style</a>.
