The accessibility-node vocabulary a widget that contributes a semantics node needs — as opposed to one that only forwards a child’s.

SemanticsCtx::push_node is (role: Role, build: impl FnOnce(&mut Node)) -> NodeId; SemanticsCtx::push_container takes the same two plus a visit: impl FnOnce(&mut SemanticsCtx) for its children. Action, Live and Toggled are lifted alongside them because they are what the build closure actually reaches for — node.add_action(Action::Click) is in eight of frust-widgets’ own widgets, and a list of exports that stopped at Node would not be closed over Node’s own signature.

For the rest of the crate, use the whole-crate frust::accesskit valve. An action to be taken on an accessibility node.

Variants

Click = 0

Do the equivalent of a single click or tap.

Focus = 1

Blur = 2

Collapse = 3

Expand = 4

CustomAction = 5

Requires ActionRequest::data to be set to ActionData::CustomAction.

Decrement = 6

Decrement a numeric value by one step.

Increment = 7

Increment a numeric value by one step.

HideTooltip = 8

ShowTooltip = 9

ReplaceSelectedText = 10

Delete any selected text in the control’s text value and insert the specified value in its place, like when typing or pasting. Requires ActionRequest::data to be set to ActionData::Value.

ScrollDown = 11

Scroll down by the specified unit.

ScrollLeft = 12

Scroll left by the specified unit.

ScrollRight = 13

Scroll right by the specified unit.

ScrollUp = 14

Scroll up by the specified unit.

ScrollIntoView = 15

Scroll any scrollable containers to make the target node visible. Optionally set ActionRequest::data to ActionData::ScrollHint.

ScrollToPoint = 16

Scroll the given object to a specified point in the tree’s container (e.g. window). Requires ActionRequest::data to be set to ActionData::ScrollToPoint.

SetScrollOffset = 17

Requires ActionRequest::data to be set to ActionData::SetScrollOffset.

SetTextSelection = 18

Requires ActionRequest::data to be set to ActionData::SetTextSelection.

SetSequentialFocusNavigationStartingPoint = 19

Don’t focus this node, but set it as the sequential focus navigation starting point, so that pressing Tab moves to the next element following this one, for example.

SetValue = 20

Replace the value of the control with the specified value and reset the selection, if applicable. Requires ActionRequest::data to be set to ActionData::Value or ActionData::NumericValue.

ShowContextMenu = 21
