Detailed Description

Once a QPainterPath object is constructed, subpaths like lines and curves can be added to the path (creating QPainterPath::LineToElement and QPainterPath::CurveToElement components).

The lines and curves stretch from the currentPosition() to the position passed as argument. The currentPosition() of the QPainterPath object is always the end position of the last subpath that was added (or the initial start point). The moveTo() function can be used to move the currentPosition() without adding a line or curve, creating a QPainterPath::MoveToElement component.

See also QPainterPath.

Member Function Documentation

bool Element::isCurveTo() const

Returns true if the element is a curve, otherwise returns false.

See also type and QPainterPath::CurveToElement.

bool Element::isLineTo() const

Returns true if the element is a line, otherwise returns false.

See also type and QPainterPath::LineToElement.

bool Element::isMoveTo() const

Returns true if the element is moving the current position, otherwise returns false.

See also type and QPainterPath::MoveToElement.

QPointF Element::operator QPointF() const

Returns the element's position.

See also x and y.

bool Element::operator!=(const Element &other) const

Returns true if this element is not equal to other; otherwise returns false.

See also operator==().

bool Element::operator==(const Element &other) const

Returns true if this element is equal to other; otherwise returns false.

See also operator!=().
