}

What the integrations provides to egui at the start of each frame.

Set the values that make sense, leave the rest at their Default::default().

You can check if egui is using the inputs using crate::Context::wants_pointer_input and crate::Context::wants_keyboard_input.

All coordinates are in points (logical pixels) with origin (0, 0) in the top left .corner.

Ii “points” can be calculated from native physical pixels using pixels_per_point = crate::Context::zoom_factor * native_pixels_per_point;

Fields

viewport_id: ViewportId

The id of the active viewport.

viewports: HashMap<ViewportId, ViewportInfo, BuildHasherDefault<NoHashHasher<ViewportId>>>

Information about all egui viewports.

screen_rect: Option<Rect>

Position and size of the area that egui should use, in points. Usually you would set this to

Some(Rect::from_min_size(Default::default(), screen_size_in_points)).

but you could also constrain egui to some smaller portion of your window if you like.

None will be treated as “same as last frame”, with the default being a very big area.

max_texture_side: Option<usize>

Maximum size of one side of the font texture.

Ask your graphics drivers about this. This corresponds to GL_MAX_TEXTURE_SIZE.

The default is a very small (but very portable) 2048.

time: Option<f64>

Monotonically increasing time, in seconds. Relative to whatever. Used for animations. If None is provided, egui will assume a time delta of predicted_dt (default 1/60 seconds).

predicted_dt: f32

Should be set to the expected time between frames when painting at vsync speeds. The default for this is 1/60. Can safely be left at its default value.

modifiers: Modifiers

Which modifier keys are down at the start of the frame?

events: Vec<Event>

In-order events received this frame.

There is currently no way to know if egui handles a particular event, but you can check if egui is using the keyboard with crate::Context::wants_keyboard_input and/or the pointer (mouse/touch) with crate::Context::is_using_pointer.

hovered_files: Vec<HoveredFile>

Dragged files hovering over egui.

dropped_files: Vec<DroppedFile>

Dragged files dropped into egui.

Note: when using eframe on Windows you need to enable drag-and-drop support using eframe::NativeOptions.

focused: bool

The native window has the keyboard focus (i.e. is receiving key presses).

False when the user alt-tab away from the application, for instance.

system_theme: Option<Theme>

Does the OS use dark or light mode?

None means “don’t know”.

Implementations

impl RawInput

pub fn viewport(&self) -> &ViewportInfo

Info about the active viewport

pub fn take(&mut self) -> RawInput

Helper: move volatile (deltas and events), clone the rest.

• Self::hovered_files is cloned.
• Self::dropped_files is moved.

pub fn append(&mut self, newer: RawInput)

Add on new input.

impl RawInput

pub fn ui(&self, ui: &mut Ui)

Trait Implementations

impl Clone for RawInput

fn clone(&self) -> RawInput

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RawInput

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

Formats the value using the given formatter.

impl Default for RawInput

fn default() -> RawInput

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RawInput

fn deserialize<__D>( __deserializer: __D ) -> Result<RawInput, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RawInput

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for RawInput

fn serialize<__S>( &self, __serializer: __S ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
