If you're already using a rectangle to determine the size of the text, why not use one half the size to determine text that should be half the size?
Besides that, there's probably not a better way to achieve what you're after, other than exposing the font size. Another option to consider, if you want to somehow get access to the font size, is to provide a function in QFontMetrics: int fontSize(const QRect &boundingRect) const I'm not sure if that makes sense for QFontMetrics' API, but I'm just throwing ideas around. :) ________________________________________ From: Harri Pasanen <[email protected]> Sent: Thursday, 29 January 2015 21:12 To: Curtis Mitch; [email protected] Subject: Re: [Interest] QML Text.Fit question We'll putting on my designer classes here: Imagine I have a rectangle on screen, let's say a sign to a shop. I want to have the title text within the sign so that it leaves 5 mm margin on both sides and top and bottom. So I compute the rectangle where the text needs to fit, exactly so that it complements the golden ratio of the larger layout. Then I need to use the same font, exactly half size elsewhere in the image, again to please my eye. At that point it is convenient to know what the initial font size was. Or how would you achieve this otherwise?
