I was trying to find an easy way to show some info in at dialog, and stumbled over DialogHeader.extraContent, but it gives an error when running: Invalid property assignment: "extraContent" is a read-only property

Dialog {
id: timersDialog;
allowedOrientations: Orientation.Portrait | Orientation.Landscape;

DialogHeader {
    id: header;
    dialog: timersDialog
    title: "Title"
    extraContent: 
        Label {
            text: "Extra content"
        }
}}

What is the property exactly for then?

Long shot but try with reserveExtraContent bool set to true

Good suggestion, but nope

In documentation of reserveExtraContent it says: "This property defaults to true if extraContent has one or more children; otherwise false." so perhaps you could try add a child item to it, instead of using it directly. I believe you can also make a subclass of it...

Edit: That's what @coderus said.

Label {

    text: "Extra content"
}

Interesting. I'll give that a try. It should be added to the docs.
