    Detailed Description

    Symbols describe how graphics and features look on a map. Different symbols are used with different geometry types. Line symbols are used to display graphics and features that are based on polyline geometries. Subclasses of this class represent specific types of line symbols.

    Member Function Documentation

    [protected] LineSymbol::LineSymbol(QObject *parent = nullptr)

    Default constructor with an optional parent.

    [override virtual] LineSymbol::~LineSymbol()

    Destructor.

    QColor LineSymbol::color() const

    Returns the color of the line.

    When getting the color (or tint color) from a symbol, the consensus value (for all layers) is reported. If there is no consensus (one or more layers have different colors), a null value is reported for the color. Likewise, setting a value for color on a symbol will apply that color to all layers the symbol contains.

    If you don't want changes to the symbol color to propagate to some of the symbol layers it contains, you can lock the color (or tint color) for those layers. If a symbol layer is color-locked, changes to the parent symbol will not affect the symbol layer. This also means that the layer will not be considered when determining a consensus color for the symbol as a whole.

    See also setColor().

    bool LineSymbol::isAntiAlias() const

    Returns whether the line should be anti-aliased.

    Defaults to true.

    void LineSymbol::setAntiAlias(bool antiAlias)

    Sets whether the line should render as antiAlias to smooth edges.

    Defaults to true.

    See also isAntiAlias().

    void LineSymbol::setColor(const QColor &color)

    Sets the color of the line.

    void LineSymbol::setWidth(float width)

    Sets the width of the line, in device independent pixels (DIPs).

    See also width().

    float LineSymbol::width() const

    Returns the width of the line, in device independent pixels (DIPs).
