The forums have several requests for text frames that automatically adjust to the content.  Several times I've told people that Inkscape can't do this.  That changes today!

The rectangle applies the Bounding Box LPE linked to the text object, then the Offset LPE for a margin.  Here's the svg for your entertainment.

Paddy_CAD,

Thank you very much for discovering this feature!  It helps a lot!  Best wishes, Roy

Paddy_CAD,

Thank you very much... This is what I'm looking for.

Best regards, Ricardo

Paddy_CAD,

this is a great trick!

Do you know if there's a way of reusing the result as some sort of text template? I've tried

• duplicate but the LPE sticks to original text
• clone, but you can only modify the original text
• group and then duplicate but the frame doesn't adapt to text anymore

Best regards

As you discovered, duplicating (or copy-pasting) a linked LPE faithfully reproduces the original link so you must update the linked LPE manually.

I played around with this a little more and I'm happy to report that the linked frame responds to all text formatting and kerning.  

(SVG rendering in this forum seems to have problems with text alignment.  It looks perfect in Inkscape on my macbook)

Very neat!

Would it be possible to restrict growing in only Y direction so that I can define my rectangle with a fixed width and have the height change when the text overflows?

Best Regards

No, it can't be done.

Well, maybe, but it's complicated.

Actually, you could try this.
