Number of characters that fit into given width

[Arthur Araruna]

I would like to be able to determine, given a string (QString) that is supposed to be displayed within a given width (qreal) area, how many of its characters would fit without overflowing that width.

Is there any helper class / function that I can use to get this information, or do I need to create my own? If I do, what measurements should I include in this calculation? I have access to the QFont and QFontMetrics objects that will be used.

Thank you.

Something like http://doc.qt.io/qt-5/qfontmetrics.html#elidedText ?

Maybe yes. Most likely to work.

The problem would be if ::ElideNone does not work as expected... Also, it would be better if I didn't have to make another QString in order to get just the number of characters.

But I'll give it a go.

Thank you.

Turns out it will not work for me.

The QString returned includes the ellipsis and there is no way to avoid them, because passing Qt::ElideNone means "do not truncate" instead of "omit the ellipsis" (as I feared).
