Resizing Column beyond Listbox Width does not show the Horizontal Scrollbar

I found a solution from 2018 Astonishingly, it was one of Emile’s ! It transpires that no matter WHAT you do to a list box, that horizontal bar will never appear unless you change the columnwidths string property to something which is full of specific values.

Is this still true in 2023? I’ve just run into it with a project refactor. The Horizontal Scrollbar is enabled, but any changes to a WidthActual value that would cause the listbox to grow wider that the defined visual area does not cause the scrollbar to appear.

I imagine if the last width specifier in the columnwidths string is *, then this is what will happen.

I thought WidthActual was read-only. I wouldn’t expect setting it to have any effect. I’ve always used ColumnWidths to adjust column sizes.

WidthActual is both read write and has been for a long time.

The original column 4 value is * (60, 170, 30, 64, *, 100), but then I set it to the StringWidth of the text being added - originally thinking that would cause the refresh and the scrollbar to appear. So, I finally learned (from that post) that I needed to update the whole list. That just seems unnecessary since the WidthActual value is Read/Write. I just looked and can’t find a feature request, so I’ll create one.
