Struct egui::WidgetRects

pub struct WidgetRects {
    by_layer: HashMap<LayerId, Vec<WidgetRect>>,
    by_id: IdMap<(usize, WidgetRect)>,
    infos: IdMap<WidgetInfo>,
}

Stores the WidgetRects of all widgets generated during a single egui update/frame.

All crate::Uis have a WidgetRect. It is created in crate::Ui::new with Rect::NOTHING and updated with the correct Rect when the crate::Ui is dropped.

Fields

by_layer: HashMap<LayerId, Vec<WidgetRect>>

All widgets, in painting order.

by_id: IdMap<(usize, WidgetRect)>

All widgets, by id, and their order in their respective layer

infos: IdMap<WidgetInfo>

Info about some widgets.

Only filled in if the widget is interacted with, or if this is a debug build.

Implementations

impl WidgetRects

pub fn layer_ids(&self) -> impl ExactSizeIterator<Item = LayerId> + '_

All known layers with widgets.

pub fn layers(&self) -> impl Iterator<Item = (&LayerId, &[WidgetRect])> + '_

pub fn get(&self, id: Id) -> Option<&WidgetRect>

pub fn order(&self, id: Id) -> Option<(LayerId, usize)>

In which layer, and in which order in that layer?

pub fn contains(&self, id: Id) -> bool

pub fn get_layer( &self, layer_id: LayerId, ) -> impl Iterator<Item = &WidgetRect> + '_

All widgets in this layer, sorted back-to-front.

pub fn clear(&mut self)

Clear the contents while retaining allocated memory.

pub fn insert(&mut self, layer_id: LayerId, widget_rect: WidgetRect)

Insert the given widget rect in the given layer.

pub fn set_info(&mut self, id: Id, info: WidgetInfo)

pub fn info(&self, id: Id) -> Option<&WidgetInfo>

Trait Implementations

impl Clone for WidgetRects

fn clone(&self) -> WidgetRects

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for WidgetRects

fn default() -> WidgetRects

Returns the “default value” for a type.

impl PartialEq for WidgetRects

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