QConicalGradient Class Reference

Member Function Documentation

QConicalGradient::QConicalGradient ()

Constructs a conical with center at (0, 0) starting the interpolation at angle 0.

See also QGradient::setColorAt(), setCenter(), and setAngle().

QConicalGradient::QConicalGradient ( const QPointF & center, qreal angle )

Constructs a conical gradient with the given center, starting the interpolation at the given angle. The angle must be specified in degrees between 0 and 360.

See also QGradient::setColorAt() and QGradient::setStops().

QConicalGradient::QConicalGradient ( qreal cx, qreal cy, qreal angle )

Constructs a conical gradient with the given center (cx, cy), starting the interpolation at the given angle. The angle must be specified in degrees between 0 and 360.

See also QGradient::setColorAt() and QGradient::setStops().

qreal QConicalGradient::angle () const

Returns the start angle of the conical gradient in logical coordinates.

See also setAngle() and stops().

QPointF QConicalGradient::center () const

Returns the center of the conical gradient in logical coordinates.

See also setCenter() and stops().

void QConicalGradient::setAngle ( qreal angle )

Sets angle to be the start angle for this conical gradient in logical coordinates.

This function was introduced in Qt 4.2.

See also angle().

void QConicalGradient::setCenter ( const QPointF & center )

Sets the center of this conical gradient in logical coordinates to center.

See also center().

void QConicalGradient::setCenter ( qreal x, qreal y )

This is an overloaded function.

Sets the center of this conical gradient in logical coordinates to (x, y).

See also center().
