Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ToplevelEnter

Toplevel entered the surface area

A ext_foreign_toplevel_handle_v1 has entered the surface area.

This event will be emitted once for every ext_foreign_toplevel_handle_v1 representing this toplevel.

Compositors are free to update the overlapping area by sending additional toplevel_enter events for the same toplevel without sending toplevel_leave in between.

Fields

toplevel: ExtForeignToplevelHandleV1

x: i32

x coordinate of the upper-left corner of the overlapping area

y: i32

y coordinate of the upper-left corner of the overlapping area

width: i32

width of the overlapping area

height: i32

height of the overlapping area

ToplevelLeave

Toplevel entered the surface area

A ext_foreign_toplevel_handle_v1 has left the surface area.

This event will be emitted once for every ext_foreign_toplevel_handle_v1 representing this toplevel.

Fields

toplevel: ExtForeignToplevelHandleV1

LayerEnter

Layer surface entered the surface area

A zwlr_layer_surface_v1 has entered the surface area.

Compositors are free to update the overlapping area by sending additional layer_enter events for the same surface without sending layer_leave in between.

The overlapping region is given surface-relative to the zwlr_layer_surface_v1 used to create this notification object.

Fields

identifier: String

unique identifier for the overlapping layer-surface

namespace: String

namespace for the layer surface

exclusive: u32

if the overlapping surface is requesting an exclusive area or not

layer: WEnum<Layer>

layer the overlapping surface sits on

x: i32

x coordinate of the upper-left corner of the overlapping area

y: i32

y coordinate of the upper-left corner of the overlapping area

width: i32

width of the overlapping area

height: i32

height of the overlapping area

LayerLeave

Layer surface left the surface area

A zwlr_layer_surface_v1 has left the surface area.

Fields

identifier: String

unique identifier for the overlapping layer-surface
