autoresize text in qml

In the process of studying QML and QtQuick, the following question arose. How can I make the text automatically reduce the font size by decreasing the element in which it is located. Now I have this method

Rectangle {id: main_windowwidth: 700height: 500property int main_w: main_window.widthRectangle {    width: 400    height: 400    anchors.centerIn: parent    color: 'green'    Text {        text: "SIZE ME!!!"        anchors.centerIn: parent        color: 'white'        font.pointSize: {            if (main_window.main_w < main_window.width)                return main_window.main_w / 35 // we need 20pt            return main_window.width / 35        }        visible: {            if (parent.width < 100)                return false            return true        }    }}

It works, but not too elegantly. Maybe there are some methods that the text automatically resized. If the wrap in the ColumnLayout does not work.

Please help. Thank you

Here my code with fontSizeMode trying:

Rectangle {id: rootwidth: 700height: 700property int mrg: 10   Rectangle {    anchors.centerIn: parent    width: 400    height: 400    color: 'green'    Text {        id: field        text: "Size me!"        minimumPointSize: 10        font.pointSize: 60        fontSizeMode: Text.Fit        color: 'white'        anchors.centerIn: parent    }}}
