Tk_GetRootCoords(3)

🎀 NAME 🎀

okay so welcome to Tk_GetRootCoords(3) from the Tk Library Procedures manual — she's here to Compute root-window coordinates of window, and yes bestie, she ate 💅

Tk_GetRootCoords - Compute root-window coordinates of window

---

✨ SYNOPSIS ✨

#include <tk.h>

Tk_GetRootCoords(tkwin, xPtr, yPtr)

---

🌸 ARGUMENTS 🌸

• Tk_Window tkwin (in) — Token for window. it's literally the little handle that tells you which window we're talking about 🫶
• int *xPtr (out) — Pointer to location in which to store root-window x-coordinate corresponding to left edge of tkwin's border ✨
• int *yPtr (out) — Pointer to location in which to store root-window y-coordinate corresponding to top edge of tkwin's border 🎀

---

🦋 DESCRIPTION 🦋

This procedure scans through the structural information maintained by Tk to compute the root-window coordinates corresponding to the upper-left corner of tkwin's border. like, it's doing the coordinate math through Tk's own structural tea, no cap 🔥

If tkwin has no border, then Tk_GetRootCoords returns the root-window coordinates corresponding to location (0,0) in tkwin. okay so no border? we're still locked in at (0,0) 💖

Tk_GetRootCoords is relatively efficient, since it does not have to communicate with the X server. highkey iconic behavior — fast because it doesn't need to chat with the X server, periodt 🌈
