- The _X_G_r_a_b_K_e_y function establishes a passive grab on the
- keyboard. In the future, the keyboard is actively grabbed
- (as for _X_G_r_a_b_K_e_y_b_o_a_r_d), the last-keyboard-grab time is set
- to the time at which the key was pressed (as transmitted
- in the _K_e_y_P_r_e_s_s event), and the _K_e_y_P_r_e_s_s event is reported
- if all of the following conditions are true:
-
- +o The keyboard is not grabbed and the specified key
- (which can itself be a modifier key) is logically
-

-
- pressed when the specified modifier keys are logi-
- cally down, and no other modifier keys are logically
- down.
-
- +o Either the grab_window is an ancestor of (or is) the
- focus window, or the grab_window is a descendant of
- the focus window and contains the pointer.
-
- +o A passive grab on the same key combination does not
- exist on any ancestor of grab_window.
-
- The interpretation of the remaining arguments is as for
- _X_G_r_a_b_K_e_y_b_o_a_r_d. The active grab is terminated automati-
- cally when the logical state of the keyboard has the spec-
- ified key released (independent of the logical state of
- the modifier keys).
-
- Note that the logical state of a device (as seen by client
- applications) may lag the physical state if device event
- processing is frozen.
-
- A modifiers argument of _A_n_y_M_o_d_i_f_i_e_r is equivalent to issu-
- ing the request for all possible modifier combinations
- (including the combination of no modifiers). It is not
- required that all modifiers specified have currently
- assigned KeyCodes. A keycode argument of _A_n_y_K_e_y is equiv-
- alent to issuing the request for all possible KeyCodes.
- Otherwise, the specified keycode must be in the range
- specified by min_keycode and max_keycode in the connection
- setup, or a _B_a_d_V_a_l_u_e error results.
-
- If some other client has issued a _X_G_r_a_b_K_e_y with the same
- key combination on the same window, a _B_a_d_A_c_c_e_s_s error
- results. When using _A_n_y_M_o_d_i_f_i_e_r or _A_n_y_K_e_y, the request
- fails completely, and a _B_a_d_A_c_c_e_s_s error results (no grabs
- are established) if there is a conflicting grab for any
- combination.
-
- _X_G_r_a_b_K_e_y can generate _B_a_d_A_c_c_e_s_s, _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 function releases the key combination on
- the specified window if it was grabbed by this client. It
- has no effect on an active grab. A modifiers of _A_n_y_M_o_d_i_-
- _f_i_e_r is equivalent to issuing the request for all possible
- modifier combinations (including the combination of no
- modifiers). A keycode argument of _A_n_y_K_e_y is equivalent to
- issuing the request for all possible key codes.
-
- _X_U_n_g_r_a_b_K_e_y can generate _B_a_d_V_a_l_u_e and _B_a_d_W_i_n_d_o_w error.

- _B_a_d_A_c_c_e_s_s A client attempted to grab a key/button combina-
- tion already grabbed by another client.

-
- _B_a_d_V_a_l_u_e Some numeric value falls outside the range of
- values accepted by the request. Unless a spe-
- cific range is specified for an argument, the
- full range defined by the argument's type is
- accepted. Any argument defined as a set of
- alternatives can generate this error.
-
- _B_a_d_W_i_n_d_o_w A value for a Window argument does not name a
- defined Window.
