What is the QMessageBox::aboutQt equivalent in QML?

Is there an equivalent of QMessageBox::aboutQt which can be used in QML? I didn't find anything suitable in the QtQuick.Dialogs module (https://doc.qt.io/qt-5/qtquickdialogs-index.html).

Solution

  • The closest match of QMessageBox::about with QML would be MessageDialog setup like this:

    import QtQuick 2.2
import QtQuick.Dialogs 1.1

MessageDialog {
    title: "Your title"
    icon: StandardIcon.Information
    text: "Your text"
    standardButtons: StandardButton.Ok
    Component.onCompleted: visible = true
}

    As for QMessageBox::aboutQt, according to this topic, in the Qt forum, there is no QML equivalent and it is better to invoke qApp->aboutQt:

    reading the docs seems there's no aboutQt for QML.

    probably better to invoke standard qApp->aboutQt from C++ class.
