Functions related to the environment’s display viewport.

Required Methods

fn width(&self) -> i32

The width of the stage viewport, in pixels.

fn height(&self) -> i32

The height of the stage viewport, in pixels.

fn orientation(&self) -> Value<Orientation>

The current screen orientation, or a wrapped None value if the environment doesn’t support multiple orientations.

fn fullscreen(&self) -> Value<bool>

True if the stage is currently fullscreen.

fn is_fullscreen_supported(&self) -> bool

Whether the stage may change its fullscreen state. False if the stage is fullscreen and can’t go into windowed mode, or vise versa.

fn resize_signal(&self) -> Signal0

Emitted after the stage size changes, such as when the window is resized or the device is rotated.

fn lock_orientation(&self, orient: Orientation)

Request to lock the orientation, so that rotating the device will not adjust the screen. Has no effect if the environment doesn’t support orientation locking. @param orient The orientation to lock to.

fn unlock_orientation(&self)

Request to unlock the orientation, so that rotating the device will adjust the screen. Has no effect if the environment doesn’t support orientation locking.

fn request_resize(&self, width: i32, height: i32)

Request that the stage be resized to a certain size.

fn request_fullscreen(&self, enable: bool)

Request that fullscreen be enabled or disabled. No effect if changing fullscreen is not supported.
