DESCRIPTION
The
_X_t_N_a_m_e_T_o_W_i_d_g_e_t
function looks for a widget whose name is the first component in the specified
names and that is a pop-up child of reference (or a normal child if reference
is a subclass of
_c_o_m_p_o_s_i_t_e_W_i_d_g_e_t_C_l_a_s_s).
It then uses that widget as the new reference and repeats the search
after deleting the first component from the specified names.
If it cannot find the specified widget,
_X_t_N_a_m_e_T_o_W_i_d_g_e_t
returns NULL.
Note that the names argument contains the name of a widget with respect to the
specified reference widget and can contain more than one widget name
(separated by periods) for widgets that are not direct children
of the specified reference widget.
If more than one child of the reference widget matches the name,
_X_t_N_a_m_e_T_o_W_i_d_g_e_t
can return any of the children.
The Intrinsics do not require that all children of a widget have unique names.
If the specified names contain more than one component
and if more than one child matches the first component,
_X_t_N_a_m_e_T_o_W_i_d_g_e_t
can return NULL if the single branch that it follows does not
contain the named widget.
That is,
_X_t_N_a_m_e_T_o_W_i_d_g_e_t
does not back up and follow other matching branches of the widget tree.
The
_X_t_W_i_n_d_o_w_T_o_W_i_d_g_e_t
function translates the specified window and display pointer into the
appropriate widget instance.
