XkbAddGeomRow(3)

🎀 NAME 🎀

okay bestie, this page is XkbAddGeomRow(3) from the XKB FUNCTIONS manual, and it's literally the row-adding bestie for keyboard geometry. it's giving main character energy. 💅

XkbAddGeomRow — add a row to a section. periodt. ✨

---

✨ SYNOPSIS ✨

XkbRowPtr XkbAddGeomRow (XkbSectionPtr section, int sz_keys);

---

🫶 ARGUMENTS 🫶

• section — the section to be updated. it's the one getting the new row, so yes, main character vibes.
• sz_keys — the number of keys to be reserved. lowkey just the key-space count, no cap.

---

💖 DESCRIPTION 💖

okay so here's the tea: Xkb provides functions to add a single new element to the top-level keyboard geometry. In each case the num_ * fields — the num_* crew — of the corresponding structure is incremented by 1. These functions do not change sz_* unless there is no more room in the array. Some of these functions fill in the values of the element's structure from the arguments. For other functions, you must explicitly write code to fill the structure's elements. fr fr, that part is on you. 🫡

The top-level geometry description includes a list of geometry properties. A geometry property associates an arbitrary string with an equally arbitrary name. Programs that display images of keyboards can use geometry properties as hints, but they are not interpreted by Xkb. No other geometry structures refer to geometry properties. iconic, honestly. 🌈

One of the components of a keyboard geometry section is one or more rows of keys. XkbAddGeomRow adds one row to the specified section. The newly created row contains space for the number of keys specified in sz_keys. They are allocated and zeroed, but otherwise uninitialized. 🦋

XkbAddGeomRow returns NULL if any of the parameters is empty or if it was not able to allocate space for the row. To allocate space for an arbitrary number of rows to a section, use the XkbAllocGeomRows function. iykyk.

vibe check: if you get NULL, that's the no-row zone — either a parameter was empty, or the row allocation didn't happen. not a slay, just a fact. 💀

🧚 STRUCTURES 🧚

here's the exact struct, bestie — this ate, and the field names are part of the lore:

typedef struct _XkbRow {
        short           top;
        short           left;
        unsigned short  num_keys;
        unsigned short  sz_keys;
        int             vertical;
        XkbKeyPtr       keys;
        XkbBoundsRec    bounds;
} XkbRowRec, *XkbRowPtr;
