gtktreeview sort string function

[Johnson Wong <jjwh tpg com au>]

Hi guys,

What compare functions does gtktreeview-columns use to sort strings?

I have my own GList sorted using g_ascii_strcasecmp(str1, str2) but this
is different then gtktreeview internal sorting function. 

The tree view puts lower case text above upper case text but
g_ascii_strcasecmp is the reverse of that eg:

tree view sorting
------
abc
hello
HELLO
xyz

g_ascii_strcasecmp
----
abc
HELLO
hello
xyz



Many Thanks
Johnson
