Struct InteractionState 

pub struct InteractionState {
    pub hovered: bool,
    pub focused: bool,
    pub pressed: bool,
    pub dragged: bool,
}

Tracks a widget’s hover/focus/pressed/dragged interaction state. See the module docs for the two opacity resolvers this feeds.

Fields

hovered: bool

focused: bool

pressed: bool

dragged: bool

Implementations

impl InteractionState

pub fn new() -> Self

A fresh state with every interaction flag clear.

pub fn set_hovered(&mut self, hovered: bool) -> bool

Record the widget’s hover state. Returns whether the flag changed — the frame source for hover gain per docs/CODE_STANDARDS.md’s Interaction Semantics hover-claiming seam (claim_hover itself requests no redraw).

pub fn set_focused(&mut self, focused: bool) -> bool

Record the widget’s focus state. Returns whether the flag changed.

pub fn set_pressed(&mut self, pressed: bool) -> bool

Record the widget’s pressed state. Returns whether the flag changed.

pub fn set_dragged(&mut self, dragged: bool) -> bool

Record the widget’s dragged state. Returns whether the flag changed.

pub fn is_active(&self) -> bool

Whether any interaction state is currently active.

pub fn resolve_opacity(&self) -> f32

The M3E-precedence overlay opacity: dragged > pressed > focused > hovered — the single highest-priority active state’s opacity, or 0.0 if none are active. The new documented default; see the module docs for how this differs from Self::max_active_opacity.

pub fn max_active_opacity(&self) -> f32

The maximum of every active state’s opacity — crate::state_layer::StateLayer’s original resolver, kept for its back-compat contract. See the module docs.
