Detailed Description

An on-screen keyboard: key styling + engine seam + commit callback.

Caller-owned plain data bound to a ra8_widget_t with ra8_widget_keyboard_init. render fills the widget rect with bg, then draws each key as a border-framed key_face face carrying its centred glyph / label in key_fg. on_input maps a touch to a key via the seam, applies it, self-invalidates for a redraw, and – on the commit edge – fires on_commit.

Invariant

border_w >= 0.

Example:

ra8_widget_keyboard_ops_t ops = {.user = &kb, .count = kb_count,
                                 .key_info = kb_info, .hit = kb_hit,
                                 .apply = kb_apply};
ra8_widget_keyboard_t kbd = {.paint = &paint, .ops = &ops,
                             .on_commit = run_search, .bg = 0x00202020U,
                             .key_face = 0x00404040U, .key_border = 0x00101010U,
                             .key_fg = 0x00FFFFFFU, .border_w = 1};
ra8_widget_t w = {};
(void)ra8_widget_keyboard_init(&w, &kbd);
