XMSETFONTUNIT(3)

✨ XmSetFontUnit — a whole function that sets the font unit value for a display ✨

okay bestie, this is XmSetFontUnit, and it lives in the library call section of the manual, which is giving very "official business" energy. it's a Motif thing. it's old. it's still here. let's get into it 💖

🌸 NAME 🌸

XmSetFontUnit — a function that sets the font unit value for a display

---

💅 SYNOPSIS 💅

#include <Xm/Xm.h>
void XmSetFontUnit(
Display * display,
int font_unit_value);

---

🦋 DESCRIPTION 🦋

so XmSetFontUnit is literally just here to hand you an external function that initializes font unit values. that's the whole job. no cap.

why would you even want that? because apps may want to specify resolution-independent data based on a global font size — like, your layout shouldn't fall apart just because someone's running a different DPI, you know? it's giving adaptable. it's giving main character. if you want the whole lore on resolution independence, go read the XmNunitType resource description in the reference pages for XmGadget, XmManager, and XmPrimitive.

and the scope? this function sets the font units for all screens on the display. every single one. all of them. periodt.

🚨 NOTE: XmSetFontUnit is obsolete and only exists for compatibility with previous releases. it is not the moment anymore. instead of using this function, you should either provide initial values, or call XtSetValues for the XmScreen resources XmNhorizontalFontUnit and XmNverticalFontUnit. do that instead, bestie, i'm begging 🙈

now, the arguments, because we do NOT skip the arguments:

• display — defines the display for which this font unit value is to be applied. like, which screen situation are we talking about here.
• font_unit_value — specifies the value to be used for both the horizontal and vertical font units in the conversion calculations. one number, two jobs. multitasking queen 👑
