[Qt-qml] QML and binding loop problem

[Valentine Silvansky]

Hi all! I've got some problem...

I have to make a elide for multiline text. Here is the code I wrote:

<pre>
Text {
	id: tempText
	visible: false
	width: parent.width
	wrapMode: Text.WordWrap
	function elideMultiline(etext, pointSize, linesCount) {
		console.log("elideMultiline: " + etext + " " + pointSize + " " + linesCount)
		tempText.font.pointSize = pointSize
		var l = etext.length
		var s = "";
		for (var i = 0; i < linesCount; i++) {
			s += "W";
			if (i < linesCount - 1)
				s += "\n"
		}
		tempText.text = s
		console.log("s = " + s)
		var maxHeight = tempText.paintedHeight
		tempText.text = etext
		while (tempText.paintedHeight > maxHeight) {
			tempText.text = etext.substring(0, l--) + "..."
		}
		return tempText.text
	}
}
Text {
	id: longText
	width: parent.width
	wrapMode: Text.WordWrap
	font.pointSize: 16
	text: tempText.elideMultiline("my very-very-very-very and very long
text with a lot of words in it and which i want to be correctly
elided", font.pointSize, 2)
}</pre>

And when running my qml I've got this output:

QML Text: Binding loop detected for property "text"

The resulting qml output is ok, function works as expected, but i've
got tons of console output messages...
What's the problem of this code?

PS: if I use Component.onCompleted: { text = "....." } no messages are printed
