XtAppSetTypeConverter(3)

💅 XtAppSetTypeConverter — bestie edition 💅

okay so this is a page from the XT FUNCTIONS part of the X Toolkit Intrinsics manual (libXt), and it's literally about teaching X how to turn one kind of thing into another kind of thing. resource converter registration, periodt. 🦋

✨ NAME ✨

XtAppSetTypeConverter, XtSetTypeConverter — register resource converter 💖

🌸 SYNTAX 🌸

#include <X11/Intrinsic.h>

void XtAppSetTypeConverter(XtAppContext app_context, const char
       *from_type, const char * to_type, XtTypeConverter converter,
       XtConvertArgList convert_args, Cardinal num_args, XtCacheType
       cache_type, XtDestructor destructor);

void XtSetTypeConverter(const char *from_type, const char *to_type,
       XtTypeConverter converter, XtConvertArgList convert_args,
       Cardinal num_args, XtCacheType cache_type, XtDestructor
       destructor);

like. look at those signatures. iconic. ✨

🎀 ARGUMENTS 🎀

• app_context — tells it which application context we're talking about, bestie. that's the whole vibe.
• converter — the type converter procedure. the actual little machine doing the converting. 🔥
• convert_args — how to compute the extra arguments you're handing to the converter, or NULL if there aren't any. 🙈
• from_type — the source type. where we're coming from. 💜
• num_args — how many extra arguments the converter gets, or zero. yes zero is allowed, slay.
• to_type — the destination type. where we're going. 🌈
• cache_type — says whether resources made by this converter are shareable or display-specific, and when they should get freed. important!! 👑
• destructor — a destroy procedure for the resources this conversion produces, or NULL if nothing extra needs to happen to deallocate what the converter made. 🧚

💖 DESCRIPTION 💖

okay so here's the tea. XtSetTypeConverter registers the type converter and the destructor you gave it in all application contexts created by the calling process — and yes, that includes any future application contexts that might get created later. it's giving "commit to the bit, everywhere, forever." 🌟

XtAppSetTypeConverter, on the other hand, is the more lowkey one: it registers the type converter in the single application context you specified. just that one. nobody else invited. 💅

and here's the part you gotta remember: if the same from_type and to_type show up in multiple calls to either function, the most recent call overrides the previous ones. newest wins, no cap. the old ones are simply not the main character anymore. 😭

mwah 💋 that's the whole page. this one came from X Version 11, libXt 1.3.1, and it's filed under XtAppSetTypeConverter(3) — go forth and convert ur types, bestie, ur gonna eat 💅✨🎀🦋
