Struct StyleContext

    pub tag: &'a str,
    pub static_disabled: bool,
    pub bind_disabled: bool,
    pub part: Option<WidgetPart>,
    pub tab_strip: bool,

}

What an element is, beyond its styles, that decides how its styles become components. Spawning reads it off the element’s attributes; a restyle reads it off the components spawning attached.

Fields

tag: &'a str

The element’s tag.

static_disabled: bool

Disabled with no bind-disabled to change it: the :disabled styles apply as the element’s own.

bind_disabled: bool

Carries bind-disabled: the :disabled styles become a state patch that comes and goes with the marker.

part: Option<WidgetPart>

The widget part the parser synthesized it as, if any.

tab_strip: bool

A <tabs> strip button.

dropdown_button: bool

A <dropdown>’s header button.

radio: bool

A <radio> that names its group and value.

page_gate: bool

The gate a page of a multi-page app mounts inside.

virtualized_for: bool

A virtualized <for> block.

in_scroll: bool

The element’s parent is a scroll container.

layout_boundary: bool

Asked for a relayout boundary in markup (layout-boundary).

Implementations
