### Event datastructure

```

typedef struct xcb_enter_notify_event_t {
    uint8_t         response_type;
    uint8_t         detail;
    uint16_t        sequence;
    xcb_timestamp_t time;
    xcb_window_t    root;
    xcb_window_t    event;
    xcb_window_t    child;
    int16_t         root_x;

```

## EVENT FIELDS

- *response\_type*

  The type of this event, in this case *XCB\_LEAVE\_NOTIFY*. This field is also present in the *xcb\_generic\_event\_t* and can be used to tell events apart from each other.

- *sequence*

  The sequence number of the last request processed by the X11 server.

- *detail*

  NOT YET DOCUMENTED.

- *time*

  NOT YET DOCUMENTED.

- *root*

  The root window for the final cursor position.

- *event*

  The window on which the event was generated.

- *child*

  If the *event* window has subwindows and the final pointer position is in one of them, then *child* is set to that subwindow, *XCB\_WINDOW\_NONE* otherwise.

- *root\_x*

  The pointer X coordinate relative to *root*'s origin at the time of the event.

- *root\_y*

  The pointer Y coordinate relative to *root*'s origin at the time of the event.

- *event\_x*

  If *event* is on the same screen as *root*, this is the pointer X coordinate relative to the event window's origin.

- *event\_y*

  If *event* is on the same screen as *root*, this is the pointer Y coordinate relative to the event window's origin.

- *state*

  NOT YET DOCUMENTED.

- *mode*

  - *same\_screen\_focus*

  NOT YET DOCUMENTED.
