<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 used to
provide 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 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 QStyle, you must similarly only expect the
default or documented arguments. The other arguments will have
uninitialized values.
<p> If you make your own <a href="qstyle.html">QStyle</a> 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.
