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

     This function is supposed to be used in a '"query-tooltip"' signal
     handler for 'GtkTreeView'.  The 'x', 'y' and 'keyboard.tip' values
     which are received in the signal handler, should be passed to this
     function without modification.

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

     gtkTreeViewGetTooltipContext(object, x, y, keyboard.tip)

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

'object': ['GtkTreeView']  a 'GtkTreeView'

     'x': [integer]  the x coordinate (relative to widget coordinates)

     'y': [integer]  the y coordinate (relative to widget coordinates)

'keyboard.tip': [logical]  whether this is a keyboard tooltip or not

_D_e_t_a_i_l_s:

     The return value indicates whether there is a tree view row at the
     given coordinates ('TRUE') or not ('FALSE') for mouse tooltips. 
     For keyboard tooltips the row returned will be the cursor row. 
     When 'TRUE', then any of 'model', 'path' and 'iter' which have
     been provided will be set to point to that row and the
     corresponding model.  'x' and 'y' will always be converted to be
     relative to 'tree.view''s bin_window if 'keyboard.tooltip' is
     'FALSE'.  

     Since  2.12

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

     A list containing the following elements: 

  retval: [logical]  whether or not the given tooltip context points to
          a row.

 'model': ['GtkTreeModel']  a pointer to receive a 'GtkTreeModel' or
          'NULL'

  'path': ['GtkTreePath']  a pointer to receive a 'GtkTreePath' or
          'NULL'

  'iter': ['GtkTreeIter']  a pointer to receive a 'GtkTreeIter' or
          'NULL'
