.SS "QwtSymbol::QwtSymbol ()"
.PP
Default Constructor
.PP
The symbol is constructed with gray interior, black outline with zero width, no size and style 'None'. 
.SS "QwtSymbol::QwtSymbol (\fBQwtSymbol::Style\fP style, const QBrush & brush, const QPen & pen, const QSize & size)"
.PP
Constructor. \fBParameters:\fP
.RS 4
\fIstyle\fP Symbol Style 
.br
\fIbrush\fP brush to fill the interior 
.br
\fIpen\fP outline pen 
.br
\fIsize\fP size 
.RE

.PP
Destructor. 
.SH "Member Function Documentation"
.PP 
.SS "const QBrush& QwtSymbol::brush () const"
.PP
Return Brush. 
.SS "void QwtSymbol::draw (QPainter * painter, const QRect & r) const\fC [virtual]\fP"
.PP
Draw the symbol into a bounding rectangle. This function assumes that the painter has been initialized with brush and pen before. This allows a much more performant implementation when painting many symbols with the same brush and pen like in curves.
.PP
\fBParameters:\fP
.RS 4
\fIpainter\fP Painter 
.br
\fIr\fP Bounding rectangle 
.RE
.PP

.SS "void QwtSymbol::draw (QPainter * painter, int x, int y) const"
.PP
Draw the symbol at a point (x,y). 
.SS "void QwtSymbol::draw (QPainter * painter, const QPoint & pos) const"
.PP
Draw the symbol at a specified point. \fBParameters:\fP
.RS 4
\fIpainter\fP Painter 
.br
\fIpos\fP Center of the symbol 
.RE
.PP

.SS "bool QwtSymbol::operator!= (const \fBQwtSymbol\fP &) const"
.PP
!= operator 
.SS "bool QwtSymbol::operator== (const \fBQwtSymbol\fP &) const"
.PP
== operator 
.SS "const QPen& QwtSymbol::pen () const"
.PP
Return Pen. 
.SS "void QwtSymbol::setBrush (const QBrush & br)"
.PP
Assign a brush. The brush is used to draw the interior of the symbol. 
.PP
\fBParameters:\fP
.RS 4
\fIbr\fP brush 
.RE
.PP

.SS "void QwtSymbol::setPen (const QPen & pn)"
.PP
Assign a pen. The pen is used to draw the symbol's outline.
.PP
\fBParameters:\fP
.RS 4
\fIpn\fP pen 
.RE
.PP

.SS "void QwtSymbol::setSize (int w, int h = -1)"
.PP
Specify the symbol's size. If the 'h' parameter is left out or less than 0, and the 'w' parameter is greater than or equal to 0, the symbol size will be set to (w,w). 
.PP
\fBParameters:\fP
.RS 4
\fIw\fP width 
.br
\fIh\fP height (defaults to -1) 
.RE
.PP

.SS "void QwtSymbol::setSize (const QSize & s)"
.PP
Set the symbol's size. 
.SS "void QwtSymbol::setStyle (\fBQwtSymbol::Style\fP s)"
.PP
Specify the symbol style. The following styles are defined:
.IP "\fBQwtSymbol::None<dd>No Style. The symbol cannot be drawn. \fP" 1c
.IP "\fBQwtSymbol::Ellipse<dd>Ellipse or circle \fP" 1c
.IP "\fBQwtSymbol::Rect<dd>Rectangle \fP" 1c
.IP "\fBQwtSymbol::Diamond<dd>Diamond \fP" 1c
.IP "\fBQwtSymbol::Triangle<dd>Triangle pointing upwards \fP" 1c
.IP "\fBQwtSymbol::DTriangle<dd>Triangle pointing downwards \fP" 1c
.IP "\fBQwtSymbol::UTriangle<dd>Triangle pointing upwards \fP" 1c
.IP "\fBQwtSymbol::LTriangle<dd>Triangle pointing left \fP" 1c
.IP "\fBQwtSymbol::RTriangle<dd>Triangle pointing right \fP" 1c
.IP "\fBQwtSymbol::Cross<dd>Cross \fP" 1c
.IP "\fBQwtSymbol::XCross<dd>Diagonal cross\fP" 1c
.PP
\fBParameters:\fP
.RS 4
\fIs\fP style 
.RE
.PP

.SS "const QSize& QwtSymbol::size () const"
.PP
Return Size. 
.SS "\fBStyle\fP QwtSymbol::style () const"
.PP
Return Style.
