Weblistbox Frozen Columns

What does Frozen Columns do in the Weblistbox? I can not find any documentation about it.

Not showing here:

@Gary_Smith

What version of Xojo? Is this a plugin?

IIRC it allows making one or more columns on the left remain static when scrolling horizontally.

2025R1.1 and it is not a plugin.

@Greg_O I tried changing the value to 1 and scrolled horizontal but it did not do anything different. The columns still scrolled out of site. I found that setting when I was looking for a way to freeze the first column but could not get it to work. Do I need to add code to turn it on?

Thanks

Not seeing that option either with 2025r1.1 here:

What OS are you using?
Can you share a sample project where you see that option? Just zip it and upload it here.

I am using Winodws 11. The option does not appear immediately. The listbox is in a container but does the same on a window. If I set the row height to 29 and turn on allow row reordering then lock all 4 sides with left and right all the way to the edge of the container and then resize the container, it will show up.

Oh, I’m able to reproduce following this steps on a mac.

Maybe @Ricardo_Cruz can give us an idea.

It looks like a feature that was planned to be shipped in the initial version of Web 2. As Greg said, it’s for fixing one or more of the left columns while scrolling horizontally, like in this example:

There is some code already taking care of it but it will probably need some work to make it work with the current version of the underlying library. If there is enough interest (please open a Feature Request), the feature can be completed.

At the moment, that property isn’t supposed to be shown in the IDE, that’s a bug.

There is already https://tracker.xojo.com/xojoinc/xojo/-/issues/70692 . I think I opened a case as well, but I keep forgetting how to find my own cases on the tracker platform.

Haha, yeah, I know, and I was schizophrenic before I even saw that.

Had a number of licenses over the years, wonder if it is possible to merge all these. But that’s off topic, I would like to see those frozen columns.
