.SH "Detailed Description"
.PP
A point in polar coordinates\&.
In polar coordinates a point is determined by an angle and a distance\&. See http://en.wikipedia.org/wiki/Polar_coordinate_system
.SH "Constructor & Destructor Documentation"
.PP
.SS "QwtPointPolar::QwtPointPolar ()\fC [inline]\fP"
Constructs a null point, with a radius and azimuth set to 0\&.0\&.
.PP
\fBSee Also:\fP
.RS 4
QPointF::isNull()
.RE
.PP
.SS "QwtPointPolar::QwtPointPolar (doubleazimuth, doubleradius)\fC [inline]\fP"
Constructs a point with coordinates specified by radius and azimuth\&.
.PP
\fBParameters:\fP
.RS 4
\fIazimuth\fP Azimuth
.br
\fIradius\fP Radius
.RE
.PP
.SS "QwtPointPolar::QwtPointPolar (const \fBQwtPointPolar\fP &other)\fC [inline]\fP"
Constructs a point using the values of the point specified\&.
.PP
\fBParameters:\fP
.RS 4
\fIother\fP Other point
.RE
.PP
.SS "QwtPointPolar::QwtPointPolar (const QPointF &p)"
Convert and assign values from a point in Cartesian coordinates
.PP
\fBParameters:\fP

.PP
.SS "\fBQwtPointPolar\fP QwtPointPolar::normalized () const"
Normalize radius and azimuth
.PP
When the radius is < 0\&.0 it is set to 0\&.0\&. The azimuth is a value >= 0\&.0 and < 2 * M_PI\&.
.PP
\fBReturns:\fP
.RS 4
Normalized point
.RE
.PP
.SS "bool QwtPointPolar::operator!= (const \fBQwtPointPolar\fP &other) const"
Compare 2 points
.PP
Two points are equal to each other if radius and azimuth-coordinates are the same\&. Points are not equal, when the azimuth differs, but other\&.azimuth() == \fBazimuth()\fP % (2 * PI)\&.
.PP
\fBReturns:\fP
.RS 4
True if the point is not equal to other; otherwise return false\&.
