get the text extent of the string up and until the letter before Dave

Then the text extent of the string after e

Then hope no one changes text size.

No.
I'm sure it's just not within Flash's tiny html subset.

I'm not sure how to apply getTextExtent() here.
Doesn't that just give me the general metrics for the TF?
e.g. how do I get to x,y of D in Dave in some long string?

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?

Cheers;

Dave
