Exposing struct members to QML from derived QQuickItem-class

adaptine

Hiall

I have a class deriving from QQuickItem with overloaded updatePaintNode among others ...
The class is registered as qmlRegisterType<DPShip>("dpship", 1, 0, "DPShip");
This works perfectly fine.

I want to have border.width and border.color properties in QML for my class.
So in DPShip.h I tried:

struct borderStruct
{
    Q_GADGET
    Q_PROPERTY(qreal width MEMBER m_width)
    Q_PROPERTY(QColor color MEMBER m_color)
    
    qreal m_width;
    QColor m_color;
};

class DPShip : public QQuickItem
{
    Q_OBJECT
    Q_PROPERTY(borderStruct border READ border WRITE setBorder NOTIFY borderChanged)

public:
    DPShip(QQuickItem *parent = Q_NULLPTR);

protected:
    QSGNode *updatePaintNode(QSGNode *oldNode, UpdatePaintNodeData *updatePaintNodeData);

    borderStruct border() const;
    setBorder(const borderStruct& border);

private:
    borderStruct border_obj;

signals:
    void borderChanged(const borderStruct &border);
}

In QML I instantiate my item as DPShip { } , which works fine as mentioned above, also Qt Creator recognizes the border property, but no members, ie. in the editor I get the error: "border" does not have members. (M17) when I write border.width for instance.

How do I do this?

我有一个从 QQuickItem 派生的类，其中包含重载的 updatePaintNode ......
该类被注册为qmlRegisterType<DPShip>("dpship", 1, 0, "DPShip");
这很好用。
我想为我的班级在 QML 中拥有border.width和border.color属性。
所以在 DPShip.h 我试过：

Hi I also want to know that qgss series draws borders. Can I see your source code? thank you
