qmllint: claims binding will not update on a signal handler (i.e. not a binding)

XMLWordPrintable

    • 740d67fbc (dev), e730c16cd (6.10)

      With this code

      import QtQuick
Item {
  DropArea {
    onDropped: (drop) => {
      console.log(drop.hasUrls)
    }
  }
}

      qmllint will complain

       

      /Users/user/Qt/6.10.0/macos/bin/qmllint test.qml 
Warning: test.qml:8:24: Reading non-constant and non-notifiable property hasUrls. Binding might not update when the property changes. [stale-property-read]
      console.log(drop.hasUrls)
                       ^^^^^^^

      But onDropped is not a binding so this warning is bogus and in my opinion it is more than ok to use/read that property since you want to use it only "at that point in time".
