Struct RotationPlugin 

pub struct RotationPlugin { /* private fields */ }

A egui::Plugin that applies per-viewport rotation transparently.

One instance per egui::Context. Change the root rotation at runtime through the registered handle:

ctx.plugin::<RotationPlugin>().lock().set_rotation(Rotation::CW270);

Implementations

impl RotationPlugin

pub fn new(rotation: Rotation) -> Self

Create a plugin rotating the root viewport by rotation.

Child viewports are left untouched unless configured with Self::set_viewport_rotation.

pub fn rotation(&self) -> Rotation

The root viewport’s rotation.

pub fn set_rotation(&mut self, rotation: Rotation)

Set the root viewport’s rotation. Takes effect on the next frame.

pub fn viewport_rotation(&self, viewport: ViewportId) -> Rotation

The rotation configured for a specific viewport (None if unconfigured).

pub fn set_viewport_rotation( &mut self, viewport: ViewportId, rotation: Rotation, )

Set the rotation for a specific viewport (e.g. a child window). Pass Rotation::None to stop rotating it.
