In my program, the user can enter a date in a entry (and some other data
too) and it'll append in a liststore/treeview.
I'm having problems sorting this date column. Since notations of dates
are different around the world ( dd/mm/, mm/dd/yy, dd-mm/yy, etc.),
how can this be done?
Do I have to replace the entry with 3 spinbuttons perhaps? But how can I
put them all in one column together, and to be sortable?
Add yet another column to your *liststore*, and use that model column
for sorting of the visible treeview column.
Depending on your application, using an integer containing seconds since
epoch[1] may be fitting, alternately you can use a string containing an
ISO date (-MM-DD, 2009-03-09 for today in my timezone), that works
very well for sorting. It doesn't really matter, as it won't be visible
for users.
