XtTranslateCoords(3)

💫 XtTranslateCoords — the XT FUNCTIONS girlies know 💫

okay bestie, so this is XtTranslateCoords, and she's a function from the XT FUNCTIONS corner of the X world. Her whole vibe? Translating widget coordinates. That's it, that's the job. 🎀

✨ NAME ✨

XtTranslateCoords — translate widget coordinates 🦋

---

🌸 SYNTAX 🌸

#include <X11/Intrinsic.h>

void XtTranslateCoords(Widget w, Position x, Position y, Position
       *rootx_return, Position *rooty_return);

like. look at her. no return value, just pure void energy. main character who does the work and dips 💅

---

💖 ARGUMENTS 💖

• rootx_return
• rooty_return — these two are the little output girlies: they return the root-relative x and y coordinates. you hand her pointers, she fills them in. give her something to write to, okay? 🫶
• x
• y — these ones are the input side of the equation: you specify the widget-relative x and y coordinates. that's where you're starting from.
• w — and this is just... the widget. the one. specifies the widget. she's the context, she's the moment, she's the whole reason any of this works. 👑

🔥 DESCRIPTION 🔥

so, real talk: XtTranslateCoords is similar to the Xlib XTranslateCoordinates function — like, they're giving the same energy, same goal, same "where is this actually on the screen" fantasy.

BUT. and this is the iconic part, no cap:

she does not generate a server request. none. zero. not a single round trip to the server. 💀

why? because all the required information already is in the widget's data structures. she's not asking anybody for anything — she already has it. local knowledge only. she ate and she didn't even need the server's help. periodt. ✨

ok but fr fr — that's the whole selling point here. same result as the Xlib version, but cheaper, because it's all sitting right there in the widget already.
