Dialog with Text as contentItem: Binding loop for property implicitWidth

[maxwell31]

Hi,

I have an error dialog:

  Dialog {
      id: errorDialog
      objectName: "errorDialog"
      title: "Error"
      property string text: ""
      contentItem: TextStandard {
          text: errorDialog.text
      }
      modal: true
      focus: true
      anchors.centerIn: parent
      standardButtons: Dialog.Ok

      onAccepted: console.log("Ok clicked")
      onRejected: console.log("Cancel clicked")
  }

which uses a customized text as contentItem:

import QtQuick 2.12
import Style 1.0

Text {
    text: ""
    property int prefferedBlockWidth: Style.fontSizeStandard*Style.fontSizeStandard*Style.lineHeightFactor*Style.lineHeightFactor
    font.family: Style.fontNameStandard
    font.pixelSize: Style.fontSizeStandard
    font.letterSpacing: 0.25
    lineHeight: Style.lineHeightFactor*Style.fontSizeStandard
    lineHeightMode: Text.FixedHeight
    wrapMode: Text.WordWrap
}

If the dialog is shown, i get the error

QML Dialog: Binding loop detected for property "implicitWidth"

But I don't understand why.

@maxwell31 Add in Dialog component

Dialog {
    width: 400
    ...

The error will go away.
