Styling Ranges of text

[patsko]

Hi,

I'm having problem with the TextArea- and/or RichText-controls in Flex. I
can't find any way to change the background color or individual lines or
characters in the control. I've tried to apply styles to tags in the
htmlText-property. But no luck there.

Is it even possible to do this in Flex3?

Thanks in advance
Patrik

I've now tried a workaround with labels/textInputs that autosizes and flows.

But I don't get the editing I want. Since I can't select text between the
inputboxes.

Does anyone have any info on the problem with background colors on specific
ranges of text?

That has been asked here before with no useful response. Basically you would
need to do it yourself. It isn't terribly hard to do, just tedious.

This is easier with using a single font/height for your code, but basically
you can use TextLineMetrics to get information about a given line of text, or
more specifically a given letter. You can then draw the background based on
those offsets.
