Noob Column Sorting Confusion using GTK4, Columnview, C, looking for a working example

PROP_STR1 = 1,

or, add PROP_0 as the first element of the enum.

The first property id must be non-zero, which means the first element in the GParamSpec array must be NULL. It’s an implementation detail of how GObject properties work.
