- _d_i_s_p_l_a_y Specifies the connection to the X server.
-
- _g_r_a_b__w_i_n_d_o_w
- Specifies the grab window.
-
- _k_e_y_b_o_a_r_d__m_o_d_e
- Specifies further processing of keyboard events.
- You can pass _G_r_a_b_M_o_d_e_S_y_n_c or _G_r_a_b_M_o_d_e_A_s_y_n_c.
-
- _o_w_n_e_r__e_v_e_n_t_s
- Specifies a Boolean value that indicates whether
- the keyboard events are to be reported as usual.
-
- _p_o_i_n_t_e_r__m_o_d_e
- Specifies further processing of pointer events.
- You can pass _G_r_a_b_M_o_d_e_S_y_n_c or _G_r_a_b_M_o_d_e_A_s_y_n_c.
-
- _t_i_m_e Specifies the time. You can pass either a
- timestamp or _C_u_r_r_e_n_t_T_i_m_e.

- The _X_G_r_a_b_K_e_y_b_o_a_r_d function actively grabs control of the
- keyboard and generates _F_o_c_u_s_I_n and _F_o_c_u_s_O_u_t events. Further
- key events are reported only to the grabbing client.
- _X_G_r_a_b_K_e_y_b_o_a_r_d overrides any active keyboard grab by this
- client. If owner_events is _F_a_l_s_e, all generated key events
- are reported with respect to grab_window. If owner_events is
- _T_r_u_e and if a generated key event would normally be reported
- to this client, it is reported normally; otherwise, the
- event is reported with respect to the grab_window. Both
- _K_e_y_P_r_e_s_s and _K_e_y_R_e_l_e_a_s_e events are always reported,
- independent of any event selection made by the client.
-
- If the keyboard_mode argument is _G_r_a_b_M_o_d_e_A_s_y_n_c, keyboard
- event processing continues as usual. If the keyboard is

- currently frozen by this client, then processing of keyboard
- events is resumed. If the keyboard_mode argument is
- _G_r_a_b_M_o_d_e_S_y_n_c, the state of the keyboard (as seen by client
- applications) appears to freeze, and the X server generates
- no further keyboard events until the grabbing client issues
- a releasing _X_A_l_l_o_w_E_v_e_n_t_s call or until the keyboard grab is
- released. Actual keyboard changes are not lost while the
- keyboard is frozen; they are simply queued in the server for
- later processing.
-
- If pointer_mode is _G_r_a_b_M_o_d_e_A_s_y_n_c, pointer event processing
- is unaffected by activation of the grab. If pointer_mode is
- _G_r_a_b_M_o_d_e_S_y_n_c, the state of the pointer (as seen by client
- applications) appears to freeze, and the X server generates
- no further pointer events until the grabbing client issues a
- releasing _X_A_l_l_o_w_E_v_e_n_t_s call or until the keyboard grab is
- released. Actual pointer changes are not lost while the
- pointer is frozen; they are simply queued in the server for
- later processing.
-
- If the keyboard is actively grabbed by some other client,
- _X_G_r_a_b_K_e_y_b_o_a_r_d fails and returns _A_l_r_e_a_d_y_G_r_a_b_b_e_d. If
- grab_window is not viewable, it fails and returns
- _G_r_a_b_N_o_t_V_i_e_w_a_b_l_e. If the keyboard is frozen by an active
- grab of another client, it fails and returns _G_r_a_b_F_r_o_z_e_n. If
- the specified time is earlier than the last-keyboard-grab
- time or later than the current X server time, it fails and
- returns _G_r_a_b_I_n_v_a_l_i_d_T_i_m_e. Otherwise, the last-keyboard-grab
- time is set to the specified time (_C_u_r_r_e_n_t_T_i_m_e is replaced
- by the current X server time).
-
- _X_G_r_a_b_K_e_y_b_o_a_r_d can generate _B_a_d_V_a_l_u_e and _B_a_d_W_i_n_d_o_w errors.
-
- The _X_U_n_g_r_a_b_K_e_y_b_o_a_r_d function releases the keyboard and any
- queued events if this client has it actively grabbed from
- either _X_G_r_a_b_K_e_y_b_o_a_r_d or _X_G_r_a_b_K_e_y. _X_U_n_g_r_a_b_K_e_y_b_o_a_r_d does not
- release the keyboard and any queued events if the specified
- time is earlier than the last-keyboard-grab time or is later
- than the current X server time. It also generates _F_o_c_u_s_I_n
- and _F_o_c_u_s_O_u_t events. The X server automatically performs an
- _U_n_g_r_a_b_K_e_y_b_o_a_r_d request if the event window for an active
- keyboard grab becomes not viewable.
