Can you set the background via CSS? That would be much easier as then you could use styles and string.replace(), dropping in html to set the styles. However, I suspect not...

Otherwise you have to use getTextExtent() to

-- find the metrics of the end of the string leading up to the word you want to highlight - so you know where to start drawing
-- work out the w and h of the actual word, so you knowhow wide / deep to draw
-- draw the rect somewhere
-- loop over the string looking for match.

Be a useful engine method, because you'll be wanting a few functions to do this tidily.

You want to draw a rectangle behind it, like a highlighter, or just make the text a different colour?

Xerte 2 desktop.

I don't need any interactivity, just a way to highlight a word or words in a string:
e.g. I would like this [word] to have a yellow highlight.

Method already exist?
