public bool ignore_hidden { get; set; }
Warning: ignore_hidden is deprecated since 3.22.
If true, unmapped widgets are ignored when determining the size of the group.
Measuring the size of hidden widgets has not worked reliably for a long time. In most cases, they will report a size of 0 nowadays, and thus, their size will not affect the other size group members. In effect, size groups will always operate as if this property was true. Use a Stack instead to hide widgets while still having their size taken into account.
