No way to change sort column programatically in GtkColumnView
GNOME Files needs a way to set the sort column at runtime from a menu action, as requested by designer.
However, doing this by calling
gtk_column_view_sort_by_column() results in the previous sort column header still drawing an arrow:
Indeed, I realize what I am doing is not supported, as per documentation of
* This function should be used to set up the initial sorting. * At runtime, users can change the sorting of a column view * by clicking on the list headers.
So, I would request to expand the scope of this method to support this use case.
I can provide a patch, for which I see two apparently simple possible solutions: either having
gtk_column_view_sort_by_column() always call
gtk_column_view_sorter_set_column(), or having
gtk_column_view_column_notify_sort() on the previous first sorte column, as
gtk_column_view_sorter_add_column() already does.
Indeed, I can workaround this whole issue by calling
gtk_column_view_sort_by_column() twice, the first time passing
NULL for the column. But this is ugly and probably the wrong thing to do.
