DietPi-Globals | whiptail has no scrollbar

[MichaIng]

This is an old issue, but I just fell over this again. I actually wanted to automatically add a scrollbar to G_WHIP_MSG if text is too long to fit on the screen. By this we could remove G_WHIP_SCROLLBOX and rely on the anyway made Y size estimation.

Strange is now, that the scrollbars do not appear with the --scrolltext flag. It took me a while to find out why some manual whiptail test succeed with this while G_WHIP does not. The reason is that the scrollbar starts AFTER the text. So if the text fills the whole whiptail y size, the scrollbars are completely hidden:

This is odd, since the scrollbar does not have any point, if the text does not fill the whole whiptail, as then there is nothing to scroll 😕. I am totally confused now as this feature has no point at all then, but can't believe that this has never been fixed for several years.
EDIT: Without --scrolltext, scrolling is not possible at all, hence the functional part of the feature works, but the visual part (scroll bars) not as intended.

If I oversee something, please give me a hint, otherwise we can remove G_WHIP_SCROLLBOX anyway and should better report this bug to the maintainer, if not already done for a long time. But couldn't find it at least on quick search.

Same on Buster btw...

Seems to have worked well back in end of 2017, not sure which distro (bottom of page): https://www.krazyworks.com/whiptail-and-dialog-snippets/

Same error reported here little earlier: https://stackoverflow.com/a/46146021
Probably not whiptail bug but newt bug.

Strange that this is so rarely mentioned. Will do a bugs.debian.org report later: https://bugs.debian.org/cgi-bin/pkgreport.cgi?dist=unstable;package=whiptail
