XtSetWMColormapWindows(3)

✨ XtSetWMColormapWindows — XT FUNCTIONS ✨

okay bestie, welcome to the XtSetWMColormapWindows(3) page 💅 this is a lil libXt function that handles the WM_COLORMAP_WINDOWS property for you, no cap.

---

💖 NAME 💖

XtSetWMColormapWindows — set the value of the WM_COLORMAP_WINDOWS property 🎀

---

🌸 SYNTAX 🌸

#include <X11/Intrinsic.h>

void XtSetWMColormapWindows(Widget widget, Widget* list, Cardinal
       count);

like. three args. she's lowkey simple 🦋

---

🫶 ARGUMENTS 🫶

• widget — tells you which widget's window the WM_COLORMAP_WINDOWS property is gonna get stored on. it must be of class Core or any subclass of it, periodt 👑
• list — the list of widgets whose windows are, like, potentially gonna be listed in the WM_COLORMAP_WINDOWS property ✨
• count — how many widgets are in list, fr fr

---

💜 DESCRIPTION 💜

so here's the tea ☕ — XtSetWMColormapWindows returns immediately if widget is not realized, or if count is zero. like, she's not even gonna try. bye 🫡

otherwise? she builds an ordered list of windows by going through each widget in list one by one, and for each one she's like:

• if that widget is not realized → ignore it, not her problem 🙈
• if that widget is realized and its colormap resource is different from the colormap resources of all the widgets whose windows are already chillin' on the window list → add that widget's window to the window list 💖

the vibe check here is: no duplicate colormaps allowed on the list, bestie. every window that makes it in has a colormap that's genuinely different from everything already there ✨

finally — and this is the main character moment 👑 — XtSetWMColormapWindows stores that resulting window list in the WM_COLORMAP_WINDOWS property on the specified widget's window. slay.
