How to elide text in TextEdit

[Qyrychen]

hi All!
There is Qml model and TableView in my application.
TextEdit is used in delegate for text displaying (I use this element because I will use QSyntaxHighlighter with it)
Also I use wrapMode: Text.NoWrap

After column width changing I want get elide string (like ThisIsATex... for example)
I use TextMetrics for text eliding (http://doc.qt.io/qt-5/qml-qtquick-te...tml#width-prop)

onWidthChanged: {
                        textMetrics.text = delegateTextEdit.text
                        textMetrics.elideWidth = delegateTextEdit.width - 10
                        var str = textMetrics.elidedText
                        console.debug(str)
 
                        //delegateTextEdit.text = str
                    }

onWidthChanged: {
                        textMetrics.text = delegateTextEdit.text
                        textMetrics.elideWidth = delegateTextEdit.width - 10
                        var str = textMetrics.elidedText
                        console.debug(str)

                        //delegateTextEdit.text = str
                    }

To copy to clipboard, switch view to plain text mode 

Problem:
- on width changing I can see correct elide text in console (in TableView it doesn't appear)

- after last line uncommented I see text only at first column in my table. Yes, text is elided but only in one way
