如何在 javascript 中定义 QML 梯度 object

Question

This is my qtquick qml code

function show_me(element) {
    console.log(element.gradient)
}


Rectangle {
    gradient: Gradient {
        GradientStop {
            position: 0
            color: "#30cfd0"
        }

        GradientStop {
            position: 1
            color: "#330867"
        }
    }

    MouseArea {
        anchors.fill: parent
        hoverEnabled: true

        onEntered: {
            show_me(parent)
        }
    }
}

The output is

qml: QQuickGradient(0x559f18a4dd40)

the output gives me a QtQuickGradient object

I wonder how do I define a QtQuickGradient object in javascript?

I want to something like:

var gradient = //QtQuickGradient (i don't know)
element.gradient = gradient

Please help me to define it

You can create the Gradient object using common Component item, for example:

Component {
    id: myGradient
    Gradient {
        GradientStop { position: 0.0; color: "red" }
        GradientStop { position: 0.5; color: "yellow" }
        GradientStop { position: 1.0; color: "green" }
    }
}

Rectangle {
    id: rect
    width: 100
    height: 100
    anchors.centerIn: parent
    color: "orange"
    Text {
        anchors.centerIn: parent
        text: "click me"
    }
    TapHandler {
        onTapped: {
            var gradient = myGradient.createObject(rect);
            rect.gradient = gradient;
        }
    }
}
