csv (comma separated value) file
i didn't find nothing about to manage (read/write) csv files with glib do you know about something that i didn't find? otherwise i might develop it thanks in advance ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Currently its pretty easy using g_file_get_contents()/g_strsplit() if you can have it all in ram, or using GIO and again, g_strsplit() on a per line basis if you need to stream it.

Cheers, -Tristan it's not so easy, for example the following csv file: a;b;c has only two columns, you cannot handle this case with a simple g_strsplit call - Paolo ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
treeview with compact indentation?
I wonder if there's a way to produce a more compact layout for a treeview with expanders? I'd like this for a case where the treeview is in a left-hand pane, alongside stuff that the tree represents. I mean, the default looks something like this, with heading 1 expanded: heading 1 item 1 item 2 But the effect I'm looking for is like: heading 1 item 1 item 2 with the children tucked under their parent. I noticed the existence of gtk_tree_view_set_level_indentation(), but this doesn't accept a negative argument. Thanks for any suggestions. -- Allin Cottrell Department of Economics Wake Forest University ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Duh, sorry for the noise: I just had to _not_ put the headings into a separate first column in the treeview.

Sorry for the noise ;-) Dont have much of an opinion if it should be in glib, we have GKeyFile wich does similar high-levelish stuff already so it might be a suitable addition. Cheers, -Tristan (interestingly my own use-case, would be a mix of both - a fixed length keyfile like header, with variable length trailing csv data).

Hi 2009/8/3 Andrea Zagli aza...@inwind.it: i didn't find nothing about to manage (read/write) csv files with glib do you know about something that i didn't find? GSF (GNOME Structured File Library)[1], which Gnumeric uses, does CSV: http://library.gnome.org/devel/gsf/stable/gsf-Text.html otherwise i might develop it 1. http://library.gnome.org/devel/gsf/stable/index.html Cheers, Joshua -- Joshua Lock ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

[...] Dont have much of an opinion if it should be in glib, we have GKeyFile wich does similar high-levelish stuff already so it might be a suitable addition. I'd rather steer people towards XML for new stuff, and for old stuff, maybe a csv library split off from gnumeric might be possible?
