Why does GroupBox not have a Border attribute in QML?

mirro

What's wrong with the following code?

GroupBox {
    title: qsTr("Synchronize")
    border{color:"#FF0000"}
}

@mirro GroupBox has no property named border -> no direct change, you could use the background property to define your own background :

 GroupBox{
        id: control
        title: qsTr("Some Text")
        anchors.fill: parent
        anchors.margins: 10

        background: Rectangle {
                y: control.topPadding - control.padding
                width: parent.width
                height: parent.height - control.topPadding + control.padding
                color: "transparent"
                border.color: "#21be2b"
                radius: 2
            }
    }

How do I set the background property Image?

@mirro

background: Image {
                ...
            }

@J-Hilk
thanks a lot.I'd like to ask last question.

How is the repaint() of GroupBox defined in QML?

J.Hilk

@mirro what exactly do you mean with repaint() ?

@J-Hilk

I believe it isn't.
GroupBox only handles the visual logic (properties and positionning).
The painting is done by its background item, its contentItem item and label item.

Generally controls are a skeleton and delegate the painting to their child item
