xcb_set_input_focus - Sets input focus
#include <xcb/xproto.h> Request function xcb_void_cookie_t xcb_set_input_focus(xcb_connection_t *conn, uint8_t revert_to, xcb_window_t focus, xcb_timestamp_t time);
conn The XCB connection to X11. 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. Specifies what happens when the focus window becomes unviewable (if focus is neither XCB_NONE nor XCB_POINTER_ROOT). focus The window to focus. All keyboard events will be reported to this window. The window must be viewable (TODO), or a xcb_match_error_t occurs (TODO). If focus is XCB_NONE (TODO), all keyboard events are discarded until a new focus window is set. If focus is XCB_POINTER_ROOT (TODO), focus is on the root window of the screen on which the pointer is on currently. 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.
Changes the input focus and the last-focus-change time. If the specified time is earlier than the current last-focus-change time, the request is ignored (to avoid race conditions when running X over the network). A FocusIn and FocusOut event is generated when focus is changed.
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_set_input_focus_checked. See xcb-requests(3) for details.
xcb_match_error_t The specified focus window is not viewable. xcb_value_error_t TODO: Reasons? xcb_window_error_t The specified focus window does not exist.
