Wrap text from bottom to top

[maxnoder1995]

How can I implement text wrapping from the bottom to the top in LabVIEW? I'm looking for a solution to format my text in a way that it starts at the bottom of a text box or display area and wraps upwards, rather than the standard top-to-bottom approach.

So your text is one long string without line delimiters and you want it to dynamically re-wrap if the font size or indicator dimensions are changed?

I assume you are talking about an indicator, not a control, right?

The math will be a bit easier if you use a fixed width font (e.g. Consolas).

Can you explain the purpose of all this?

If each line is a linefeed delimited string to be dynamically appended to the indicator, all you might need is concatenate the new data on top.

Try this.

Saved by "going through a tunnel".

I (carelessly) read this post, and thought the Original Poster had a ListBox (which is what I thought he meant by "Text Box") and wanted to present it with the initial Selected Item the last item in the list (instead of the first).  By the time I got off the train and was able to set up my laptop again, I saw the posts from Christian and Paul, and figured out that I was "answering the wrong question".

That's a bit of a hack, because applying the operation twice does not restore the original string as one might foolishly expect. Might be OK is some use cases.

(Easiest to demonstrate by repeating the operation a couple of times. We get more and more empty lines in-between the text lines. Not easy to fix.)

OK.  Just remove the concatenation of the End of Line Constant and it will work as you like.

Even then, applying the operation twice (or any even times) does not return to the original text in general but scrambles the words.

We still need to hear from the OP to see what problem should actually be solved.... 😄

This seems to work.
