XtGetApplicationResources(3)

💖 XtGetApplicationResources — bestie edition 💖

ok so we're in the XT FUNCTIONS part of the manual (section 3, iykyk) and today's main characters are XtGetApplicationResources and XtVaGetApplicationResources. they're here to help you obtain application resources. slay. ✨

🌸 NAME 🌸

XtGetApplicationResources, XtVaGetApplicationResources — obtain application resources 🎀

---

🦋 SYNTAX 🦋

#include <X11/Intrinsic.h>

void XtGetApplicationResources(Widget w, XtPointer base, XtResourceList
       resources, Cardinal num_resources, ArgList args, Cardinal
       num_args);

void XtVaGetApplicationResources(Widget w, XtPointer base,
       XtResourceList resources, Cardinal num_resources, ...);

like… the second one is the vibe-y varargs twin, no cap 💅

✨ ARGUMENTS ✨

• args — this is the argument list that overrides the resources you got from the resource database. it's giving "actually, I want this instead" energy.
• base — the base address of the subpart data structure where the resources should be written. it's the little home address where your resources are moving in 🏠
• num_args — how many arguments are in that argument list. just a number, bestie.
• num_resources — how many resources are in the resource list. also just a number.
• resources — the resource list for the subpart. this is the menu of what you're asking for 📋
• w — the widget that wants resources for a subpart, or the widget that identifies which resource database to search. main character widget energy honestly 👑
• ... — the variable arguments that override the resources obtained from the resource database. it's the vibes-based version of args.

💜 DESCRIPTION 💜

ok so XtGetApplicationResources starts by taking the widget you passed in — which is usually an application shell — and uses it to construct a resource name and class list. Then (yes, capital-T Then, iconic) it retrieves the resources from the argument list, the resource database, or the resource list default values. three sources, one function, we love a multitasker 🫶

after adding base to each address, XtGetApplicationResources copies the resources into the address given in the resource list. boom. delivered. 📦✨

now listen carefully because this part matters: if args is NULL, then num_args must be zero. periodt. but — plot twist — if num_args is zero, the argument list is not referenced at all. so like, it doesn't even look at it. not even a glance. 🙈

and the portable way to specify application resources? declare them as members of a structure and pass the address of the structure as the base argument. that's the move. that's the whole strategy. structure girlies stay winning 🌈
