Struct ZwlrOutputManagerV1

pub struct ZwlrOutputManagerV1 { /* private fields */ }

Available on crate feature server only.

output device configuration manager

This interface is a manager that allows reading and writing the current output device configuration.

Output devices that display pixels (e.g. a physical monitor or a virtual output in a window) are represented as heads. Heads cannot be created nor destroyed by the client, but they can be enabled or disabled and their properties can be changed. Each head may have one or more available modes.

Whenever a head appears (e.g. a monitor is plugged in), it will be advertised via the head event. Immediately after the output manager is bound, all current heads are advertised.

Whenever a head’s properties change, the relevant wlr_output_head events will be sent. Not all head properties will be sent: only properties that have changed need to.

Whenever a head disappears (e.g. a monitor is unplugged), a wlr_output_head.finished event will be sent.

After one or more heads appear, change or disappear, the done event will be sent. It carries a serial which can be used in a create_configuration request to update heads properties.

The information obtained from this protocol should only be used for output configuration purposes. This protocol is not designed to be a generic output property advertisement protocol for regular clients. Instead, protocols such as xdg-output should be used.

See also the Request enum for this interface.

Implementations

impl ZwlrOutputManagerV1

pub fn head(&self, head: &ZwlrOutputHeadV1)

introduce a new head

This event introduces a new head. This happens whenever a new head appears (e.g. a monitor is plugged in) or after the output manager is bound.

pub fn done(&self, serial: u32)

sent all information about current configuration

This event is sent after all information has been sent after binding to the output manager object and after any subsequent changes. This applies to child head and mode objects as well. In other words, this event is sent whenever a head or mode is created or destroyed and whenever one of their properties has been changed. Not all state is re-sent each time the current configuration changes: only the actual changes are sent.

This allows changes to the output configuration to be seen as atomic, even if they happen via multiple events.

A serial is sent to be used in a future create_configuration request.

pub fn finished(&self)

the compositor has finished with the manager

This event indicates that the compositor is done sending manager events. The compositor will destroy the object immediately after sending this event, so it will become invalid and the client should release any resources associated with it.
