label in cell inside Clist

[Jose Eusebio Roza Pando <jeroza alu uah es>]

Hi ,
I use this senteces for setting a int in a cell inside Clist.
   text=g_strdup_printf("     %d",(int)histoD3[i]);
   gtk_clist_set_text(GTK_CLIST(clist),i,0,text);

the label (the int) is shown justify to left,
How can I justify to right?
Thanks a lot
     Eusebio
