If you sort the string array it sorts the value of each entry.
The key of the items are keep to the entry and are mangled.
Here now as [1], [0]

I asume next hapens:

1)
When you put the array into the combobox the entry order (keys)
are in sequential order restored by qt. 
Setting 'combobox.sort=FALSE' should not change the values.
Setting 'combobox.sort=true' should  order the values.


2) The values are in the same order as the array after 'astring.sort'
and the keys are mangled.
Setting 'combobox.sort=FALSE' tels QT to restore the sequential order 
by key values.



Alternatives:

When you copy the sorted values from astring entry by entry to a new 
string array (bstring) wich reorders the key in the same order as values.
After the copy do combobox1.list=bstring.

You can also add the items with foreach to the combobox after the
astring.sort.
In this way 'combobox.sort=FALSE' should not change the order.

As Benoit says

The '-' and '_' (minus and underscore) behaviour with sorting in qt
is also noticed in konqueror with filenames.
starting with '-' to get it as first in directory listing does not work.
It takes the first alfabet character instead of '-' or '_'.
Anyway at my box with kubuntu.
