Struct TouchSelectionSnapshot 

pub struct TouchSelectionSnapshot { /* private fields */ }

Where a touch selection’s ends are laid out this frame, and what the gesture is doing to them.

Each end is the caret line box at that end in window coordinates: zero width, one line tall, at the character boundary. An empty selection has both ends at the caret. Built only by Base; a presentation layer reads it to draw the handles and place the edit menu.

Implementations

impl TouchSelectionSnapshot

pub const fn start(&self) -> Bounds<Pixels>

The caret line box before the first selected character.

pub const fn end(&self) -> Bounds<Pixels>

The caret line box after the last selected character.

pub const fn edge(&self, edge: SelectionEdge) -> Bounds<Pixels>

The caret line box at the given end.

pub const fn is_edge_visible(&self, edge: SelectionEdge) -> bool

Whether the given end is in view. A handle is drawn only for an end that is; the menu anchors to the ends that are.

pub fn is_empty(&self) -> bool

Whether the selection is a bare caret, which gets a menu but no handles.

pub fn bounds(&self) -> Option<Bounds<Pixels>>

The smallest box holding the ends in view, for anchoring the edit menu. None when the whole selection is scrolled away.

pub const fn is_menu_open(&self) -> bool

Whether the edit menu is open. It closes while a handle is dragged and reopens when the drag ends.

pub const fn dragging(&self) -> Option<SelectionEdge>

The end currently being dragged by its handle.
