Enum FocusChange

pub enum FocusChange {
    Current,
    Offset(Count, bool),
    Position(MovePosition),
    PreviouslyFocused,
    Direction1D(MoveDir1D, Count, bool),
    Direction2D(MoveDir2D, Count),
}

This represents what UI element is targeted during an Action.

Variants

Current

Target the currently focused UI element.

Offset(Count, bool)

Target the n^th element from the beginning. The first element is numbered 1.

If the specified n is greater than the number of elements, and bool is true, target the last element. Otherwise, do nothing.

Position(MovePosition)

Target the element at MovePosition in the element list.

PreviouslyFocused

Target the previously focused element.

Direction1D(MoveDir1D, Count, bool)

Target the element n times away in MoveDir1D direction.

If moving n times would go past the first or last element, and bool is true, wrap around to the other end of the element list and continue from there. Otherwise, do nothing.

Direction2D(MoveDir2D, Count)

Target the element n times away in MoveDir2D direction.

Trait Implementations

impl Clone for FocusChange

fn clone(&self) -> FocusChange

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FocusChange

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for FocusChange

fn eq(&self, other: &FocusChange) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
