}

One node of the access tree (kui_access_tree): what assistive technology sees. role is KUI_ROLE_, flags KUI_ACCESS_HAS_ / FOCUSED / CHECKED bits saying which optional fields hold, actions the KUI_ACCESS_* bits the node accepts through kui_input_access. Strings are borrowed until the next kui_access_tree on the context.

Fields

key: u64

parent: u64

The nearest semantic ancestor; 0 for the root.

origin: u32

role: u32

flags: u32

actions: u32

name: KuiStr

description: KuiStr

value: KuiStr

The node’s one string value (KUI_ACCESS_HAS_VALUE): an editor’s text, or a slider’s value_text — the platform has one slot, and a slider that named its reading reads as that instead of its number.

x: f32

Logical px, viewport coordinates, cut to the node’s clip (zero-size on the clip’s edge when wholly clipped).

y: f32

w: f32

h: f32

caret: u32

Byte offsets into value (KUI_ACCESS_HAS_VALUE / HAS_SELECTION).

selection_start: u32

selection_end: u32

value_now: f32

A slider’s position and range (KUI_ACCESS_HAS_NUMBER / MIN / MAX).

value_min: f32

value_max: f32

scroll_x: f32

A scroll view’s offsets and range (KUI_ACCESS_HAS_SCROLL).

scroll_y: f32

scroll_max_x: f32

scroll_max_y: f32

anchor_run: u64

An editor’s caret (focus_*) and the selection’s other end (anchor_*) as run positions (KUI_ACCESS_HAS_TEXT_SELECTION): a run key from kui_access_runs and a character index into it.

anchor_char: u32

focus_run: u64

focus_char: u32

run_count: u32

How many runs kui_access_runs returns for this node.

pos_in_set: u32

“3 of 7” (KUI_ACCESS_HAS_POS_IN_SET / HAS_SET_SIZE): the item’s zero-based ordinal among its list’s or tab list’s items, and the count on that container.

set_size: u32

orientation: u32

KUI_ORIENTATION_* (0 = unset: this node is not a composite container). How the container arranges its items, from its own dir.
