_D_e_s_c_r_i_p_t_i_o_n:

     Retrieves the focus chain of the container, if one has been set
     explicitly. If no focus chain has been explicitly set, GTK+
     computes the focus chain based on the positions of the children.
     In that case, GTK+ stores 'NULL' in 'focusable.widgets' and
     returns 'FALSE'.

_U_s_a_g_e:

     gtkContainerGetFocusChain(object)

_A_r_g_u_m_e_n_t_s:

'object': ['GtkContainer']          a 'GtkContainer'

_V_a_l_u_e:

     A list containing the following elements: 

  retval: [logical] 'TRUE' if the focus chain of the container  has
          been set explicitly.

'focusable.widgets': [list]  location to store the focus chain of the
          container, or 'NULL'. You should free this list using
          'gListFree()' when you are done with it, however no
          additional reference count is added to the individual widgets
          in the focus chain.
