.SH MEMBER FUNCTION DOCUMENTATION
.SH "QStyle::QStyle ()"
Constructs a QStyle.
.SH "QStyle::~QStyle ()\fC [virtual]\fR"
Destroys the style and frees all allocated resources.
.SH "int QStyle::defaultFrameWidth () const"
\fBThis function is obsolete.\fR It is provided to keep old source working. We strongly advise against using it in new code.
.SH "void QStyle::drawComplexControl ( ComplexControl control, QPainter * p, const QWidget * widget, const QRect & r, const QColorGroup & cg, SFlags how = Style_Default, SCFlags sub = SC_All, SCFlags subActive = SC_None, const QStyleOption & opt = QStyleOption::Default ) const\fC [pure virtual]\fR"
Draws the ComplexControl \fIcontrol\fR using the painter \fIp\fR in the area \fIr\fR. Colors are used from the color group \fIcg\fR. The \fIsub\fR argument specifies which SubControls to draw. Multiple SubControls can be OR'ed together. The \fIsubActive\fR argument specifies which SubControl is active.
.PP
The rect \fIr\fR should be in logical coordinates. Reimplementations of this function should use visualRect() to change the logical coordinates into screen coordinates when using drawPrimitive() and drawControl().
.PP
The \fIhow\fR argument is used to control how the ComplexControl is drawn. Multiple flags can OR'ed together. See the table below for an explanation of which flags are used with the various ComplexControls.
.PP
The \fIwidget\fR argument is a pointer to a QWidget or one of its subclasses. The widget can be cast to the appropriate type based on the value of \fIcontrol\fR. The \fIopt\fR argument can be used to pass extra information required when drawing the ComplexControl. Note that \fIopt\fR may be the default value even for ComplexControls that can make use of the extra options. See the table below for the appropriate \fIwidget\fR and \fIopt\fR usage:
