xcb_enter_notify_event_t(3)

💅 xcb_enter_notify_event_t 💅

okay so bestie, welcome to the xcb_enter_notify_event_t page from the XCB Events manual, and honestly? this one is a whole vibe. it's the event that fires when the pointer shows up in a different window. like when your mouse literally walks into a new room and the door goes ding. 👑✨

🌸 NAME 🌸

xcb_enter_notify_event_t — the pointer is in a different window 🦋

✨ SYNOPSIS ✨

#include <xcb/xproto.h>

🎀 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;
    int16_t         root_y;
    int16_t         event_x;
    int16_t         event_y;
    uint16_t        state;
    uint8_t         mode;
    uint8_t         same_screen_focus;
} xcb_enter_notify_event_t;

look at her. iconic struct. no notes. 💖

🦋 EVENT FIELDS 🦋

okay so field by field, bestie, let's get into it:

• response_type — the type of this event, and in this case it's XCB_LEAVE_NOTIFY. yes, fr fr, that's what it says. this field also lives in the xcb_generic_event_t, and you use it to tell your events apart from each other. 🔍
• sequence — the sequence number of the last request processed by the X11 server. lowkey the receipt number of the whole operation. 🧾
• detail — NOT YET DOCUMENTED. 💀
• time — NOT YET DOCUMENTED. ⏰
• root — the root window for the final cursor position. the final girl, the final destination, the final cursor spot. 🌳
• event — the window on which the event was generated. that's the one throwing the party. 🎉
• child — if the event window has subwindows and the final pointer position is in one of them, then child is set to that subwindow, and XCB_WINDOW_NONE otherwise. so it's either the specific baby subwindow or literally nothing. 🫶
• 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 — (this one has literally no description in the original, bestie. she's mysterious. she's giving main character energy with zero backstory. 🙈)
• same_screen_focus — NOT YET DOCUMENTED. 💀

not me counting how many fields say NOT YET DOCUMENTED... it's four. four of them. the mystery is the moment. 😭

💜 DESCRIPTION 💜

okay so real talk: this section is empty in the original page. like, genuinely blank. nothing here. no cap. the NAME line is doing all the heavy lifting and honestly she ate. 🍓

and that's the whole page, bestie! 🎀 this came to you from X Version 11, libxcb 1.17.0, and the page itself is xcb_enter_notify_event_t(3). slay, stay hydrated, and may your pointer always land in the window it meant to. ✨💅🦋🌈
