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.

Member Type Documentation
QStyleOption::StyleOptionDefault
This enum value can be passed as the optional argument to any QStyle
function.
QStyleOption::Default
MEMBER FUNCTION DOCUMENTATIONQStyleOption::QStyleOption ( StyleOptionDefault = Default )
The default option. This can always be passed as the optional argument
to QStyle functions.
QStyleOption::QStyleOption ( int in1 )
Pass one integer, in1. For example, headerSection.
QStyleOption::QStyleOption ( int in1, int in2 )
Pass two integers, in1 and in2. For example, linewidth and
midlinewidth.
QStyleOption::QStyleOption ( int in1, int in2, int in3, int in4 )
Pass four integers, in1, in2, in3 and in4.
QStyleOption::QStyleOption ( QMenuItem * m )
Pass a menu item, m.
QStyleOption::QStyleOption ( QMenuItem * m, int in1 )
Pass a menu item and an integer, m and in1.
QStyleOption::QStyleOption ( QMenuItem * m, int in1, int in2 )
Pass a menu item and two integers, m, in1 and in2.
QStyleOption::QStyleOption ( const QColor & c )
Pass a color, c.
QStyleOption::QStyleOption ( QTab * t )
Pass a QTab, t.
QStyleOption::QStyleOption ( QListViewItem * i )
Pass a QListViewItem, i.
QStyleOption::QStyleOption ( QCheckListItem * i )
Pass a QCheckListItem, i.
QStyleOption::QStyleOption ( Qt::ArrowType a )
Pass an Qt::ArrowType, a.
QStyleOption::QStyleOption ( const QRect & r )
Pass a QRect, r.
QStyleOption::QStyleOption ( QWidget * w )
Pass a QWidget, w.
Qt::ArrowType QStyleOption::arrowType () const

called; otherwise the return value is undefined.
int QStyleOption::frameShape () const
Returns a QFrame::Shape value if the appropriate constructor was
called; otherwise the return value is undefined.
int QStyleOption::headerSection () const
Returns the header section if the appropriate constructor was called;
otherwise the return value is undefined.
bool QStyleOption::isDefault () const
Returns TRUE if the option was constructed with the default
constructor; otherwise returns FALSE.
int QStyleOption::lineWidth () const
Returns the line width if the appropriate constructor was called;
otherwise the return value is undefined.
QListViewItem * QStyleOption::listViewItem () const
Returns a QListView item if the appropriate constructor was called;
otherwise the return value is undefined.
int QStyleOption::maxIconWidth () const
Returns the maximum width of the menu item check area if the
appropriate constructor was called; otherwise the return value is
undefined.
QMenuItem * QStyleOption::menuItem () const
Returns a menu item if the appropriate constructor was called;
otherwise the return value is undefined.
int QStyleOption::midLineWidth () const
Returns the mid-line width if the appropriate constructor was called;
otherwise the return value is undefined.
QRect QStyleOption::rect () const
Returns a rectangle if the appropriate constructor was called;
otherwise the return value is undefined.
QTab * QStyleOption::tab () const
Returns a QTabBar tab if the appropriate constructor was called;
otherwise the return value is undefined.
int QStyleOption::tabWidth () const
