Struct TextGrips 

pub struct TextGrips { /* private fields */ }

The grips of a text selection on a touchscreen: at its start a stem down the first selected line’s leading edge with a knob above it, at its end a stem down the last line’s trailing edge with a knob below, in the selection’s accent. A finger drags either end; the knobs are hit at a constant target on screen whatever the zoom.

Implementations

impl TextGrips

pub fn new(start: Rect, end: Rect, target: f64) -> TextGrips

Grips for a selection whose first line covers start and last line end on screen, each knob as easy to hit as target pixels.

pub fn knob(&self, grip: TextGrip) -> Point

The centre of grip’s knob on screen.

pub fn reach_below(&self) -> f64

The lowest a grip’s target reaches on screen: what floats below the selection stands below this.

pub fn grip_at(&self, point: Point) -> Option<TextGrip>

The grip point (screen) takes, nearest first.

pub fn draw(&self, scene: &mut Scene, base: Affine, theme: &Theme)

Paint the grips, base mapping screen pixels to the scene.

Trait Implementations

impl Clone for TextGrips

fn clone(&self) -> TextGrips

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TextGrips

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

Formats the value using the given formatter.

impl PartialEq for TextGrips

fn eq(&self, other: &TextGrips) -> 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.
