Struct WpCursorShapeDeviceV1

pub struct WpCursorShapeDeviceV1 { /* private fields */ }

Available on crate feature wayland and Linux only.

cursor shape for a device

This interface allows clients to set the cursor shape.

This interface has no events.

Implementations

impl WpCursorShapeDeviceV1

pub fn destroy(&self)

destroy the cursor shape device

Destroy the cursor shape device.

The device cursor shape remains unchanged.

pub fn set_shape(&self, serial: u32, shape: Shape)

set device cursor to the shape

Sets the device cursor to the specified shape. The compositor will change the cursor image based on the specified shape.

The cursor actually changes only if the input device focus is one of the requesting client’s surfaces. If any, the previous cursor image (surface or shape) is replaced.

The “shape” argument must be a valid enum entry, otherwise the invalid_shape protocol error is raised.

This is similar to the wl_pointer.set_cursor and zwp_tablet_tool_v2.set_cursor requests, but this request accepts a shape instead of contents in the form of a surface. Clients can mix set_cursor and set_shape requests.

The serial parameter must match the latest wl_pointer.enter or zwp_tablet_tool_v2.proximity_in serial number sent to the client. Otherwise the request will be ignored.

impl PartialEq<Weak<WpCursorShapeDeviceV1>> for WpCursorShapeDeviceV1

fn eq(&self, other: &Weak<WpCursorShapeDeviceV1>) -> 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.
