XtRegisterDrawable(3)

💖 XtRegisterDrawable — the XT FUNCTIONS manual, bestie edition 🎀

okay so like. you know how the Intrinsics event dispatcher is out here doing the most, and sometimes you've got a drawable that isn't a widget's window but you still want it to know which widget it belongs to? yeah. that's this. it's XtRegisterDrawable(3) and it is lowkey iconic. let's get into it 💅

✨ NAME ✨

XtRegisterDrawable — register a drawable with the Intrinsics event dispatcher 🦋

---

🌸 SYNTAX 🌸

#include <X11/Intrinsic.h>

void XtRegisterDrawable(Display* display, Drawable drawable, Widget
       widget);

void XtUnregisterDrawable(Display* display, Drawable drawable);

bestie look at that include. <X11/Intrinsic.h> and you're in. two functions, no cap. one to register, one to unregister. matching set fr fr 🫶

---

💜 ARGUMENTS 💜

• display — specifies the drawable's display. yeah the whole Display* situation. that one.
• drawable — specifies the drawable to register. it's giving "the thing we're talking about."
• widget — specifies the widget to register the drawable for. the main character of this whole operation, honestly 👑

🧚 DESCRIPTION 🧚

so. XtRegisterDrawable associates the specified drawable with the specified widget so that future calls to XtWindowToWidget with the drawable will return the widget. like, you're basically setting them up. matchmaking. shipping them, even. 💖

and it doesn't stop there — the default event dispatcher will dispatch future core events that arrive with the drawable to the widget as though the event contained the widget's window. as though. key detail, do not skip: the event itself will not be changed in any way when being passed to even handler or action procedures. it's cosplaying as a window event, but underneath it's still exactly what it was. no edits. periodt.

💀 danger zone, fr fr: if the drawable is already registered with another widget, or if the drawable is the window of a widget in the client's widget tree, the results of calling XtRegisterDrawable are undefined. not "a little weird." not "we'll see." undefined. don't do it. i'm begging 🙈

XtUnregisterDrawable removes an association created with XtRegisterDrawable. it's the breakup arc. 🦋

💀 and also: if the drawable is the window of a widget in the client's widget tree, the results of calling XtUnregisterDrawable are undefined. same energy. same warning. take it seriously bestie.
