QML: Binding loop detected for property "implicitHeight":

Question

I get this message in QtCreator output:

file:///C:/.../foo.qml:428:5: QML PopupWarning: Binding loop detected for property "implicitHeight":
qrc:/qt-project.org/imports/QtQuick/Controls/FluentWinUI3/Dialog.qml:16:5

"PopupWarning.qml":

import QtQuick
import QtQuick.Controls


Dialog {
    parent: Overlay.overlay

    property alias text : dialogText.text

    anchors.centerIn: parent
    width: parent.width/2

    dim: true
    modal: true

    //implicitHeight: dialogText.height

    Text {
        id: dialogText
        width: parent.width
        font.pointSize: 15
    }
}

The problem is that I cannot specify exact height, because the Text inside dialog may be of various lengths. The same with the title. Also, standardButtons may or may not be present. And I would like to keep the Dialog size as small as possible. The code works, but I would like to prevent all warnings.

Question: is there some way to calculate the height of the Dialog/Popup in this situation?

Answer 1

I found a way to calculate the height in my case:

height: (standardButtons != Dialog.NoButton) ? header.height + footer.height + dialogText.height + 35 : header.height + dialogText.height + 35

The value of 35 comes from this equation (when you did not specify the dialog height):

Component.onCompleted: console.log(height - dialogText.height)

Visually it looks exactly the same, even if I change the font size
