`CheckboxGroup::root_with`

ソースを見る

pub fn root_with(self, root: Element) -> Element

Decorate an application-owned group root without adding layout or appearance. Pair it with a [`crate::Field`] label, or with [`crate::Element::accessibility_labelled_by`], to name the group.

`CheckboxGroup::root`

ソースを見る

pub fn root(self) -> Element

Create the unstyled root part. Use [`Self::root_with`] to supply an existing element.

`CheckboxGroup::checkbox_with`

ソースを見る

pub fn checkbox_with(self, value: impl Into<ElementId>, checkbox: Element) -> Element

Decorate one application-owned checkbox for `value`. The part reuses the existing [`Checkbox`] descriptor, so the checkbox role, exact on/off/mixed semantics, click behavior, and desktop pointer contract are identical to a standalone checkbox. A disabled group disables every item.

`CheckboxGroup::checkbox`

ソースを見る

pub fn checkbox(self, value: impl Into<ElementId>) -> Element

Create the unstyled checkbox part. Use [`Self::checkbox_with`] to supply an existing element.

`CheckboxGroup::indicator_with`

ソースを見る

pub fn indicator_with(self, indicator: Element) -> Element

Hide an application-owned indicator inside one item from the accessible name.

`CheckboxGroup::indicator`

ソースを見る

pub fn indicator(self) -> Element

Create the unstyled indicator part. Use [`Self::indicator_with`] to supply an existing element.

`CheckboxGroup::parent_with`

ソースを見る

pub fn parent_with(self, parent: Element) -> Element

Decorate the application-owned parent checkbox. Its checked state is derived: on when every declared value is checked, mixed when only some are, and off when none are. QuickGUI retains no separate parent value, so the parent can never disagree with its children.

`CheckboxGroup::parent`

ソースを見る

pub fn parent(self) -> Element

Create the unstyled parent part. Use [`Self::parent_with`] to supply an existing element.
