    Member Function Documentation

    ScaleRangeDisplayFilter::ScaleRangeDisplayFilter(const QString &name, const QString &whereClause, double minScale, double maxScale, QObject *parent = nullptr)

    Creates a new ScaleRangeDisplayFilter with the specified name, where clause, and scale range.

    • name - A descriptive name for this display filter.
    • whereClause - A SQL expression that defines which features are rendered.
    • minScale - The minimum scale at which this display filter is applied.
    • maxScale - The maximum scale at which this display filter is applied.
    • parent - The optional parent QObject.

    A maxScale greater than the minScale will create an invalid scale display filter.

    [override virtual] ScaleRangeDisplayFilter::~ScaleRangeDisplayFilter()

    Destructor.

    double ScaleRangeDisplayFilter::maxScale() const

    Returns the maximum scale at which this display filter is applied.

    This display filter is only applied when zoomed further out than the maximum scale. Set this property to allow current scale of the map to determine when this display filter is applied. A value of 0 indicates this display filter is applied without an upper limit. The default value is 0.

    See also setMaxScale().

    double ScaleRangeDisplayFilter::minScale() const

    Returns the minimum scale at which this display filter is applied.

    This display filter is only applied when zoomed further in than the minimum scale. Set this property to allow current scale of the map to determine when this display filter is applied. A value of 0 indicates this display filter is applied without a lower limit. The default value is 0.

    void ScaleRangeDisplayFilter::setMaxScale(double maxScale)

    Sets the maxScale to maxScale.

    void ScaleRangeDisplayFilter::setMinScale(double minScale)
