Try switching the sizing to what is needed. Something like
...
gint combo_id=gtk_combo_box_get_active(combo);
if(combo_id==0)
{
g_print("%i\n", gtk_tree_view_column_get_width(column2));
gtk_tree_view_column_set_sizing(GTK_TREE_VIEW_COLUMN(column2),
GTK_TREE_VIEW_COLUMN_FIXED);
gtk_tree_view_column_set_fixed_width(GTK_TREE_VIEW_COLUMN(column2), 25);
gtk_tree_view_column_set_sizing(GTK_TREE_VIEW_COLUMN(column2),
GTK_TREE_VIEW_COLUMN_AUTOSIZE);
gtk_tree_view_column_set_resizable(GTK_TREE_VIEW_COLUMN(column2), TRUE);
}
...
Then when you start the program, get the saved values, set as fixed and then
switch to autosize.
