xcb_map_notify_event_t(3)

💖 xcb_map_notify_event_t — the XCB Events girlies' guide 💖

okay so bestie, welcome to xcb_map_notify_event_t(3) from the XCB Events manual, X Version 11 era, libxcb flavored. this whole page is about one (1) very specific little guy: the event that yells "a window was mapped!!" 🪟✨

---

✨ NAME ✨

xcb_map_notify_event_t — a window was mapped 🎀

like. that's it. that's the whole job. a window showed up on screen and this event is the receipt.

---

🌸 SYNOPSIS 🌸

#include <xcb/xproto.h>

🦋 Event datastructure 🦋

typedef struct xcb_map_notify_event_t {
    uint8_t      response_type;
    uint8_t      pad0;
    uint16_t     sequence;
    xcb_window_t event;
    xcb_window_t window;
    uint8_t      override_redirect;
    uint8_t      pad1[3];
} xcb_map_notify_event_t;

not the pad0 and the pad1[3] just vibing in there doing absolutely nothing 💅 they're padding, they're decorative, they're the accessories of the struct. leave them alone.

👑 EVENT FIELDS 👑

• response_type — the type of this event, and in this case it's literally XCB_MAP_NOTIFY. this field is also chillin' in the xcb_generic_event_t, so you can use it to tell events apart from each other. it's giving name tag at a party 🏷️
• sequence — the sequence number of the last request that the X11 server actually processed. it's the "which one of my requests was this a response to" tracker, fr fr.
• event — the window which was mapped, or its parent, depending on whether StructureNotify or SubstructureNotify was selected. so which window you get here? depends on your subscription, bestie 🫶
• window — the window that was mapped. the actual main character here 🌟
• override_redirect — window managers should ignore this window if override_redirect is 1. that's a whole instruction to the WM, not a suggestion. if it's 1, WM, look away, this window is not your business 🙈

💀 DESCRIPTION 💀
