Sorting GtkListStore date column
I'm fairly new to GTK programming, and I'm helping out on an open source GTK-based project (gcvs, part of the cvsgui project.) We have a GtkListStore with a column containing date. The column is specified as G_TYPE_STRING. When sorted, it does an alphanumeric sort, so in English it puts all the Fridays together first, followed by all the Mondays, Saturdays, Sundays, etc. Obviously, I want to sort this in date sequence. How do I accomplish this? I searched the archives before posting and couldn't find anything applicable. Thanks. -- Guy Rouillier ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

You can sort on a hidden column in the list store (that is, one not displayed in a tree view) which has, say, this format: MMDDSS Sorry, that should of course be MMDDHHMMSS (expressed numerically).

Thanks, Chris and Fredderic for the suggestions. Fredderic, gCvs is is a desktop GUI to manage CVS repositories, so the date range for listed files can span multiple years. Hence, a day-of-the-week approach won't work. I'll use the approach of storing the time_t corresponding to each displayed date in a hidden column, and use that hidden column as the sort column for the date column.
