XtGetGC(3)

💅 XtGetGC — from the XT FUNCTIONS girlies

okay so bestie, welcome to the XT FUNCTIONS manual, page XtGetGC(3). this one's short and sweet and it's giving "shareable GCs only, no take-backs" ✨

---

🎀 NAME 🎀

XtGetGC, XtReleaseGC — obtain and destroy a shareable GC. literally that's the whole job, and they ate 💅

---

✨ SYNTAX ✨

#include <X11/Intrinsic.h>

GC XtGetGC(Widget w, XtGCMask value_mask, XGCValues *values);

void XtReleaseGC(Widget w, GC gc);

---

🦋 ARGUMENTS 🦋

• gc — the GC you want deallocated. yes, the one you're letting go. it's giving closure 🥲
• values — the actual values for this GC. like, the real ones, fr fr.
• value_mask — which fields of the values are specified. it's the receipts for what you're claiming 👑
• w — the widget. the main character here, obviously.

---

💖 DESCRIPTION 💖

so XtGetGC returns a shareable, read-only GC. the parameters to this function are the same as those for XCreateGC except that a widget is passed instead of a display — yes bestie, widget instead of display, that's the plot twist 🫶

here's the part you need to really internalize: XtGetGC shares only GCs in which all values in the GC returned by XCreateGC are the same. not some of them. all of them. periodt.

and no, it does not use the value_mask provided to determine which fields of the GC a widget considers relevant. that is not what that mask is for, bestie, do not come for it.

so what is value_mask doing? it's used only to tell the server which fields should be filled in with widget data and which it should fill in with default values. that's it. that's the whole assignment 💀

for further information about value_mask and values, see XCreateGC in the Xlib - C Language X Interface. go read your homework, i believe in you 🌸

then XtReleaseGC deallocates the specified shared GC. say bye, blow a kiss, release the memory 🎀
