In the experiments I've done with making SVG objects act like HTML <textarea>s: listening for keystrokes, handling backspacing and word-wrap and so forth, I have generally used .getBBox() to determine how wide a rendered piece of text is. Once it gets to be too wide for its rectangle then I start a new line. I've noticed that other people, when approaching this task, tend to use .getComputedTextLength.
If T is a variable refering to a <text>, then the values of T.getComputedTextLength(); T.getBBox().width tend to differ from each other by just a few pts., with T.getBBox().width actually being a bit smaller in the typical case. The W3C 1.1 reco for getComputedTextLength() reads as follows: The total sum of all of the advance values from rendering all of the characters within this element, including the advance value on the glyphs (horizontal or vertical), the effect of properties 'kerning', 'letter-spacing' and 'word-spacing' and adjustments due to attributes dx and dy on 'tspan' elements. For non-rendering environments, the user agent shall make reasonable assumptions about glyph metrics. but don't quite understand what it is doing that getBBox().width doesn't do. There are several of the special text handling functions whose raison d'etre I don't quite understand, but perhaps if I understand this one, the others will start to make sense. Might someone be able to remove my misunderstanding?
