How can I remove the sort indicator in a GtkTreeViewColumn while preserving the collation of the columns?

I found it can be done with not applying set_sort_column_id

to a tree column . We have to do this programmatically, using a method set_clickable

for the column where you don't want the arrow to appear in its header, then using signal_connect

for a signal clicked

and binding it to a functionwhich will use the get_sort_column_id

modelsto get the current sort order: GTK_SORT_ASCENDING

or GTK_SORT_DESCENDING

then apply the sort order backwards using set_sort_column_id

in the model .
