conn
The XCB connection to X11.
 

REPLY FIELDS

response_type
The type of this reply, in this case XCB_GET_INPUT_FOCUS. This field is also present in the xcb_generic_reply_t and can be used to tell replies apart from each other.
sequence
The sequence number of the last request processed by the X11 server.
length
The length of the reply, in words (a word is 4 bytes).
revert_to
One of the following values:
XCB_INPUT_FOCUS_NONE
The focus reverts to XCB_NONE, so no window will have the input focus.
XCB_INPUT_FOCUS_POINTER_ROOT
The focus reverts to XCB_POINTER_ROOT respectively. When the focus reverts, FocusIn and FocusOut events are generated, but the last-focus-change time is not changed.
XCB_INPUT_FOCUS_PARENT
The focus reverts to the parent (or closest viewable ancestor) and the new revert_to value is XCB_INPUT_FOCUS_NONE.
XCB_INPUT_FOCUS_FOLLOW_KEYBOARD
NOT YET DOCUMENTED. Only relevant for the xinput extension.
TODO: NOT YET DOCUMENTED.
focus
TODO: NOT YET DOCUMENTED.
