Hey,guys
code：

Dialog
    footer:DialogButtonBox {
             standardButtons: DialogButtonBox.Ignore| DialogButtonBox.Retry| DialogButtonBox.Abort
             onAccepted: console.log("Ok clicked")
             onRejected: console.log("Cancel clicked")
             delegate:Button{
                text: DialogButtonBox.name
             }
｝

this code result is:button have no name.
How to get the name of relevant button?
Thank you for any advice!
