- The _X_t_P_o_p_u_p 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 Generates an error if the shell's popped_up field is

- already
-
- _T_r_u_e.
-
- +o Calls the callback procedures on the shell's
- popup_callback list.
-
- +o Sets the shell popped_up field to _T_r_u_e, the shell
- spring_loaded field to _F_a_l_s_e, and the shell grab_kind
- field from grab_kind.
-
- +o If the shell's create_popup_child field is non-NULL,
- _X_t_P_o_p_u_p calls it with popup_shell as the parameter.
-
- +o If 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:
-
- XtAddGrab(popup_shell, (grab_kind == XtGrabExclusive), False)
-
- +o Calls _X_t_R_e_a_l_i_z_e_W_i_d_g_e_t with popup_shell specified.
-
- +o Calls _X_M_a_p_W_i_n_d_o_w with popup_shell specified.
-
- The _X_t_P_o_p_u_p_S_p_r_i_n_g_L_o_a_d_e_d function performs exactly as _X_t_P_o_p_u_p
- except that it sets the shell _s_p_r_i_n_g__l_o_a_d_e_d field to _T_r_u_e
- and always calls _X_t_A_d_d_G_r_a_b with _e_x_c_l_u_s_i_v_e _T_r_u_e and
- _s_p_r_i_n_g__l_o_a_d_e_d _T_r_u_e.
-
- The _X_t_C_a_l_l_b_a_c_k_N_o_n_e, _X_t_C_a_l_l_b_a_c_k_N_o_n_e_x_c_l_u_s_i_v_e, and
- _X_t_C_a_l_l_b_a_c_k_E_x_c_l_u_s_i_v_e functions call _X_t_P_o_p_u_p with the shell
- specified by the client data argument and grab_kind set as
- the name specifies. _X_t_C_a_l_l_b_a_c_k_N_o_n_e, _X_t_C_a_l_l_b_a_c_k_N_o_n_e_x_c_l_u_s_i_v_e,
- and _X_t_C_a_l_l_b_a_c_k_E_x_c_l_u_s_i_v_e specify _X_t_G_r_a_b_N_o_n_e,
- _X_t_G_r_a_b_N_o_n_e_x_c_l_u_s_i_v_e, and _X_t_G_r_a_b_E_x_c_l_u_s_i_v_e, respectively. Each
- function then sets the widget that executed the callback
- list to be insensitive by using _X_t_S_e_t_S_e_n_s_i_t_i_v_e. Using these
- functions in callbacks is not required. In particular, an
- application must provide customized code for callbacks that
- create pop-up shells dynamically or that must do more than
- desensitizing the button.
-
- _M_e_n_u_P_o_p_u_p is known to the translation manager, which must
- perform special actions for spring-loaded pop-ups. Calls to
- _M_e_n_u_P_o_p_u_p in a translation specification are mapped into
- calls to a nonexported action procedure, and the translation
- manager fills in parameters based on the event specified on
- the left-hand side of a translation.
-
- If _M_e_n_u_P_o_p_u_p is invoked on _B_u_t_t_o_n_P_r_e_s_s (possibly with
- modifiers), the translation manager pops up the shell with
- grab_kind set to _X_t_G_r_a_b_E_x_c_l_u_s_i_v_e and spring_loaded set to
- _T_r_u_e. If _M_e_n_u_P_o_p_u_p is invoked on _E_n_t_e_r_W_i_n_d_o_w (possibly with

- modifiers), the translation manager pops up the shell with
- grab_kind set to _X_t_G_r_a_b_N_o_n_e_x_c_l_u_s_i_v_e and spring_loaded set to
- _F_a_l_s_e. Otherwise, the translation manager generates an
- error. When the widget is popped up, the following actions
- occur:
-
- +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 Generates an error if the shell's popped_up field is
- already _T_r_u_e.
-
- +o Calls the callback procedures on the shell's
- popup_callback list.
-
- +o Sets the shell popped_up field to _T_r_u_e and the shell
- grab_kind and spring_loaded fields appropriately.
-
- +o If the shell's create_popup_child field is non-NULL, it
- is called with popup_shell as the parameter.
-
- +o Calls:
-
- XtAddGrab(popup_shell, (grab_kind == XtGrabExclusive), spring_loaded)
-
- +o Calls _X_t_R_e_a_l_i_z_e_W_i_d_g_e_t with popup_shell specified.
-
- +o Calls _X_M_a_p_W_i_n_d_o_w with popup_shell specified.
-
- (Note that these actions are the same as those for _X_t_P_o_p_u_p.)
- _M_e_n_u_P_o_p_u_p tries to find the shell by searching 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 up the shell with
- the appropriate parameters. Otherwise, it moves up the
- parent chain as needed. If _M_e_n_u_P_o_p_u_p gets to the
- application widget and cannot find a matching shell, it
- generates an error.
