Struct VisualState 

pub struct VisualState(/* private fields */);

Visual state the tree tracks on the widget’s behalf.

Widgets do not track hover or press themselves. The tree does, and it marks the node dirty when any of these change — which is the whole reason a stale-pixel bug cannot come from a widget forgetting to invalidate on hover.

Implementations

impl VisualState

pub const NONE: Self

Nothing set.

pub const HOVERED: Self

The pointer is over this widget.

pub const PRESSED: Self

A pointer button went down on this widget and has not come up.

pub const FOCUSED: Self

This widget has keyboard focus.

pub const DISABLED: Self

This widget, or an ancestor, is disabled.

pub const fn contains(self, other: Self) -> bool

Returns true if every bit in other is set.

pub const fn set(self, other: Self, on: bool) -> Self

Sets or clears other.

pub const fn is_empty(self) -> bool

Returns true if no bit is set.
