- _c_a_l_l__d_a_t_a Specifies the callback data, which is not used by
- this procedure.

- _c_l_i_e_n_t__d_a_t_a
- Specifies a pointer to the _X_t_P_o_p_d_o_w_n_I_D structure.
-
- _p_o_p_u_p__s_h_e_l_l
- Specifies the widget shell to pop down.

- The _X_t_P_o_p_d_o_w_n function performs the following:
-
- +o Calls _X_t_C_h_e_c_k_S_u_b_c_l_a_s_s to ensure popup_shell is a
- subclass of _S_h_e_l_l.
-
- +o Checks that popup_shell is currently popped_up;
- otherwise, it generates an error.
-
- +o Unmaps popup_shell's window.
-
- +o If popup_shell's grab_kind is either _X_t_G_r_a_b_N_o_n_e_x_c_l_u_s_i_v_e
- or _X_t_G_r_a_b_E_x_c_l_u_s_i_v_e, it calls _X_t_R_e_m_o_v_e_G_r_a_b.
-
- +o Sets pop-up shell's popped_up field to _F_a_l_s_e.
-
- +o Calls the callback procedures on the shell's
- popdown_callback list.
-
- The _X_t_C_a_l_l_b_a_c_k_P_o_p_d_o_w_n function casts the client data
- parameter to an _X_t_P_o_p_d_o_w_n_I_D pointer:

- typedef struct {

- Widget enable_widget;
- } XtPopdownIDRec, *XtPopdownID;
- The shell_widget is the pop-up shell to pop down, and the
- enable_widget is the widget that was used to pop it up.
-
- _X_t_C_a_l_l_b_a_c_k_P_o_p_d_o_w_n calls _X_t_P_o_p_d_o_w_n with the specified
- shell_widget and then calls _X_t_S_e_t_S_e_n_s_i_t_i_v_e to resensitize
- the enable_widget.
-
- If a shell name is not given, _M_e_n_u_P_o_p_d_o_w_n calls _X_t_P_o_p_d_o_w_n
- with the widget for which the translation is specified. If
- a shell_name is specified in the translation table,
- _M_e_n_u_P_o_p_d_o_w_n tries to find the shell by looking up the widget
- tree starting at the parent of the widget in which it is
- invoked. If it finds a shell with the specified name in the
- pop-up children of that parent, it pops down the shell;
- otherwise, it moves up the parent chain as needed. If
- _M_e_n_u_P_o_p_d_o_w_n gets to the application top-level shell widget
- and cannot find a matching shell, it generates an error.
