NAME
xcb_allow_events - release queued events
SYNOPSIS
#include <xcb/xproto.h>
Request function
xcb_void_cookie_t xcb_allow_events(xcb_connection_t *conn, uint8_t mode,
xcb_timestamp_t time);
REQUEST ARGUMENTS
conn The XCB connection to X11.
mode One of the following values:
XCB_ALLOW_ASYNC_POINTER
For AsyncPointer, if the pointer is frozen by the client, pointer
event processing continues normally. If the pointer is frozen twice by
the client on behalf of two separate grabs, AsyncPointer thaws for
both. AsyncPointer has no effect if the pointer is not frozen by the
client, but the pointer need not be grabbed by the client.
TODO: rewrite this in more understandable terms.
XCB_ALLOW_SYNC_POINTER
For SyncPointer, if the pointer is frozen and actively grabbed by the
client, pointer event processing continues normally until the next
ButtonPress or ButtonRelease event is reported to the client, at which
time the pointer again appears to freeze. However, if the reported
event causes the pointer grab to be released, then the pointer does
not freeze. SyncPointer has no effect if the pointer is not frozen by
the client or if the pointer is not grabbed by the client.
XCB_ALLOW_REPLAY_POINTER
For ReplayPointer, if the pointer is actively grabbed by the client
and is frozen as the result of an event having been sent to the client
(either from the activation of a GrabButton or from a previous
AllowEvents with mode SyncPointer but not from a GrabPointer), then
the pointer grab is released and that event is completely reprocessed,
this time ignoring any passive grabs at or above (towards the root)
the grab-window of the grab just released. The request has no effect
if the pointer is not grabbed by the client or if the pointer is not
frozen as the result of an event.
XCB_ALLOW_ASYNC_KEYBOARD
For AsyncKeyboard, if the keyboard is frozen by the client, keyboard
event processing continues normally. If the keyboard is frozen twice
by the client on behalf of two separate grabs, AsyncKeyboard thaws for
both. AsyncKeyboard has no effect if the keyboard is not frozen by the
client, but the keyboard need not be grabbed by the client.
XCB_ALLOW_SYNC_KEYBOARD
For SyncKeyboard, if the keyboard is frozen and actively grabbed by
the client, keyboard event processing continues normally until the
next KeyPress or KeyRelease event is reported to the client, at which
time the keyboard again appears to freeze. However, if the reported
event causes the keyboard grab to be released, then the keyboard does
not freeze. SyncKeyboard has no effect if the keyboard is not frozen
by the client or if the keyboard is not grabbed by the client.
XCB_ALLOW_REPLAY_KEYBOARD
For ReplayKeyboard, if the keyboard is actively grabbed by the client
and is frozen as the result of an event having been sent to the client
(either from the activation of a GrabKey or from a previous
AllowEvents with mode SyncKeyboard but not from a GrabKeyboard), then
the keyboard grab is released and that event is completely
reprocessed, this time ignoring any passive grabs at or above (towards
the root) the grab-window of the grab just released. The request has
no effect if the keyboard is not grabbed by the client or if the
keyboard is not frozen as the result of an event.
XCB_ALLOW_ASYNC_BOTH
For AsyncBoth, if the pointer and the keyboard are frozen by the
client, event processing for both devices continues normally. If a
device is frozen twice by the client on behalf of two separate grabs,
AsyncBoth thaws for both. AsyncBoth has no effect unless both pointer
and keyboard are frozen by the client.
XCB_ALLOW_SYNC_BOTH
For SyncBoth, if both pointer and keyboard are frozen by the client,
event processing (for both devices) continues normally until the next
ButtonPress, ButtonRelease, KeyPress, or KeyRelease event is reported
to the client for a grabbed device (button event for the pointer, key
event for the keyboard), at which time the devices again appear to
freeze. However, if the reported event causes the grab to be released,
then the devices do not freeze (but if the other device is still
grabbed, then a subsequent event for it will still cause both devices
to freeze). SyncBoth has no effect unless both pointer and keyboard
are frozen by the client. If the pointer or keyboard is frozen twice
by the client on behalf of two separate grabs, SyncBoth thaws for both
(but a subsequent freeze for SyncBoth will only freeze each device
once).
time Timestamp to avoid race conditions when running X over the network.
The special value XCB_CURRENT_TIME will be replaced with the current server
time.
DESCRIPTION
Releases queued events if the client has caused a device (pointer/keyboard) to freeze due
to grabbing it actively. This request has no effect if time is earlier than the last-grab
time of the most recent active grab for this client or if time is later than the current X
server time.
RETURN VALUE
Returns an xcb_void_cookie_t. Errors (if any) have to be handled in the event loop.
If you want to handle errors directly with xcb_request_check instead, use
xcb_allow_events_checked. See xcb-requests(3) for details.
ERRORS
xcb_value_error_t
You specified an invalid mode.
