Text implicit width

[Mouli]

Dear All

I need to determine Text box width based on the text.
I could see difference in sizes when I use Text metrics w.r.t. implicitWidth.
For few of the cases textMetrics.width is not giving the actual width that is needed for the given text.

But when I use implicitWidth i dont see any issue. Any thoughts on this?
Is it Ok to use implicitWidth ?

Text {
id: txt
text: qsTr("This is Test sample")

	width: textMetrics.width //txt.implicitWidth
	height: 14
	elide: Text.ElideRight
	font.pixelSize:   11
	font.family:"Arial"
	color: "#2B2D2E"
	font.letterSpacing: 0

}

TextMetrics {
id: textMetrics
font: txt.font
text: txt.text
}
