XtCreateWindow(3)

✨ XtCreateWindow ✨

okay bestie, welcome to the XT FUNCTIONS corner of the manual, where today's main character is XtCreateWindow(3) — a lil window-creation convenience function that does the fiddly bits for you 🫶

---

🌸 NAME 🌸

XtCreateWindow — window creation convenience function. it's giving "I'll make the window so you don't have to" 💅

---

🎀 SYNTAX 🎀

#include <X11/Intrinsic.h>

void XtCreateWindow(Widget w, unsigned int window_class, Visual *visual,
       XtValueMask value_mask, XSetWindowAttributes *attributes);

no cap, that's the whole signature. copy it exactly, she's precise 👑

---

🦋 ARGUMENTS 🦋

• attributes — the window attributes you're handing off to the XCreateWindow call. it's literally the vibe sheet for your new window ✨
• value_mask — tells everyone which attribute fields to actually use. like a little checklist of what matters here 🎯
• visual — the visual type, which is usually CopyFromParent. so normally you just let it inherit, periodt 🌈
• w — the widget that supplies the x,y coordinates and so on. she's the source of truth for placement 📍
• window_class — the Xlib window class, for example InputOutput, InputOnly, or CopyFromParent. pick your fighter 💖

---

👑 DESCRIPTION 👑

so here's the tea, bestie: XtCreateWindow calls the Xlib XCreateWindow function, feeding it values from the widget structure plus the parameters you passed in. then — and this is the important bit — it assigns the freshly created window to the widget's window field. slay, the widget now has a window 🪟✨

and like, it doesn't just grab random stuff. XtCreateWindow evaluates these specific fields of the Core widget structure:

• depth
• screen
• parent -> core.window
• x
• y
• width
• height
• border_width

that's the whole list, no more no less, and yes it's exactly eight of them, we love a tidy roster 🧚

fr fr: if you're expecting it to peek at anything outside those Core fields, it does not. those eight are the moment.
