    \qmltype RectangleShape
    \inqmlmodule QtQuick.Shapes.DesignHelpers
    \brief A filled rectangle with an optional border.
    \since QtQuick 6.10
 
    RectangleShape is used to fill areas with solid color or gradients and to
    provide a rectangular border.
 
    Each Rectangle item is painted using either a solid fill color, specified
    using the \l fillColor property, or a gradient, defined using one of the \l
    ShapeGradient subtypes and set using the \l gradient property. If both a
    color and a gradient are specified, the gradient is used.
 
    An optional border can be added to a rectangle with its own color and
    thickness by setting the \l strokeColor and \l strokeWidth properties.
    Setting the color to \c transparent creates a border without a fill color.
 
    Rounded rectangles can be drawn using the \l radius property. The radius
    can also be specified separately for each corner. Additionally, \l bevel
    can be applied on any corner to cut it off sharply.
 
    RectangleShape's default value for \l {QtQuick.Shapes::Shape::preferredRendererType} is
    \c Shape.CurveRenderer.
