Struct Minimap 

pub struct Minimap { /* private fields */ }

A small copy of the content with a rectangle around what is in view, linked to a ZoomPanView by the same ZoomView. A press or a drag moves the view there, and so do the arrow keys (with Shift, further).

use ravenrs_core::{Color, ImageData, Size};
use ravenrs_reactive::State;
use ravenrs_widgets::{Minimap, ZoomView};

let view = State::new(ZoomView::at(2.0));
if let Some(thumbnail) = ImageData::from_fn(64, 48, |_, _| Color::rgb(0.3, 0.4, 0.5)) {
    let map = Minimap::image(view.binding(), thumbnail).content_size(Size::new(6400.0, 4800.0));
}

Implementations

impl Minimap

pub fn image(view: Binding<ZoomView>, image: ImageData) -> Minimap

A map showing image, usually a small version of the content.

pub fn custom( view: Binding<ZoomView>, content: Size, draw: impl Fn(ZoomPanPaint, &mut Scene) + 'static, ) -> Minimap

A map showing what draw draws, for content of this size in units of the caller.

pub fn content_size(self, content: Size) -> Minimap

The size of the content the view shows, when image is a smaller version of it.

pub fn max_size(self, width: f32, height: f32) -> Minimap

The most width and height, in logical pixels (160 each by default). The map takes the proportions of the content inside that.

pub fn press_zoom(self, scale: f32) -> Minimap

A press while everything is in view zooms to this scale, there. Without it, such a press does nothing, since there is nowhere to go.

pub fn label(self, label: impl Into<String>) -> Minimap

The name screen readers announce, instead of the one in Labels.

impl View for Minimap

fn build(&self, cx: &mut BuildCx<'_>) -> NodeId

Creates this view’s node for the current build.

fn type_name(&self) -> &'static str
