- XVisibilityNotifyEvent - VisibilityNotify event structure
-
- SSTTRRUUCCTTUURREESS
- The structure for _V_i_s_i_b_i_l_i_t_y_N_o_t_i_f_y events contains:
-
- typedef struct {
- int type; /* VisibiltyNotify */
- unsigned long serial; /* # of last request processed by server */
- Bool send_event; /* true if this came from a SendEvent request */
- Display *display; /* Display the event was read from */
- Window window;
- int state;
- } XVisibilityEvent;
-
- When you receive this event, the structure members are set
- as follows.
-
- The type member is set to the event type constant name
- that uniquely identifies it. For example, when the X
- server reports a _G_r_a_p_h_i_c_s_E_x_p_o_s_e event to a client applica-
- tion, it sends an _X_G_r_a_p_h_i_c_s_E_x_p_o_s_e_E_v_e_n_t structure with the
- type member set to _G_r_a_p_h_i_c_s_E_x_p_o_s_e. The display member is
- set to a pointer to the display the event was read on.
- The send_event member is set to _T_r_u_e if the event came
- from a _S_e_n_d_E_v_e_n_t protocol request. The serial member is
- set from the serial number reported in the protocol but
- expanded from the 16-bit least-significant bits to a full
- 32-bit value. The window member is set to the window that
- is most useful to toolkit dispatchers.
-
- The window member is set to the window whose visibility
- state changes. The state member is set to the state of
- the window's visibility and can be _V_i_s_i_b_i_l_i_t_y_U_n_o_b_s_c_u_r_e_d,
- _V_i_s_i_b_i_l_i_t_y_P_a_r_t_i_a_l_l_y_O_b_s_c_u_r_e_d, or _V_i_s_i_b_i_l_i_t_y_F_u_l_l_y_O_b_s_c_u_r_e_d.
- The X server ignores all of a window's subwindows when
- determining the visibility state of the window and pro-
- cesses _V_i_s_i_b_i_l_i_t_y_N_o_t_i_f_y events according to the following:
-
- +o When the window changes state from partially
- obscured, fully obscured, or not viewable to viewable
- and completely unobscured, the X server generates the
- event with the state member of the _X_V_i_s_i_b_i_l_i_t_y_E_v_e_n_t
- structure set to _V_i_s_i_b_i_l_i_t_y_U_n_o_b_s_c_u_r_e_d.
-
- +o When the window changes state from viewable and com-
- pletely unobscured or not viewable to viewable and
- partially obscured, the X server generates the event
- with the state member of the _X_V_i_s_i_b_i_l_i_t_y_E_v_e_n_t struc-
- ture set to _V_i_s_i_b_i_l_i_t_y_P_a_r_t_i_a_l_l_y_O_b_s_c_u_r_e_d.
