Detailed Description

Wayland output metadata used to match a configured display name.

Constructor & Destructor Documentation

monitor_t()

wl::monitor_t::monitor_t ( wl_output * output )

explicit

Track a Wayland output and its advertised modes.

Parameters

output

Wayland output object being described.

Member Function Documentation

listen()

void wl::monitor_t::listen

(

zxdg_output_manager_v1 *

output_manager

)

Attach xdg-output and wl-output listeners for this monitor.

Parameters

output_manager

xdg-output manager used to query logical monitor metadata.

wl_done()

void wl::monitor_t::wl_done ( wl_output * )

inline

Acknowledge completion of a wl-output metadata update.

Retain the wl-output listener signature while ignoring the output argument.

wl_geometry()

void wl::monitor_t::wl_geometry ( wl_output * , std::int32_t , std::int32_t , std::int32_t , std::int32_t , std::int32_t , const char * , const char * , std::int32_t  )

inline

Ignore physical wl-output geometry; monitor placement comes from xdg-output metadata.

Retain the wl-output listener signature while ignoring all event arguments.

wl_mode()

void wl::monitor_t::wl_mode	(	wl_output *	wl_output,
		std::uint32_t	flags,
		std::int32_t	width,
		std::int32_t	height,
		std::int32_t	refresh )

Store the active pixel mode reported by wl-output.

Parameters

wl_output	Wayland output.
flags	Bit flags that modify the requested operation.
width	Frame or display width in pixels.
height	Frame or display height in pixels.
refresh	Output refresh rate in mHz.

wl_scale()

void wl::monitor_t::wl_scale ( wl_output * , std::int32_t  )

inline

Ignore wl-output scale; capture uses the active pixel mode and xdg-output logical size.

Retain the wl-output listener signature while ignoring both event arguments.

xdg_description()

void wl::monitor_t::xdg_description	(	zxdg_output_v1 *	,
		const char *	description )

Store the xdg-output human-readable monitor description.

Parameters

description

Human-readable description used in log output.

xdg_name()

void wl::monitor_t::xdg_name ( zxdg_output_v1 * , const char * name )

inline

Store the xdg-output logical monitor name.

Parameters

name	Human-readable name to assign.

xdg_position()

void wl::monitor_t::xdg_position	(	zxdg_output_v1 *	,
		std::int32_t	x,
		std::int32_t	y )

Store the logical monitor position reported by xdg-output.

Parameters

x	Horizontal coordinate reported by Wayland.
y	Vertical coordinate reported by Wayland.

xdg_size()

void wl::monitor_t::xdg_size	(	zxdg_output_v1 *	,
		std::int32_t	width,
		std::int32_t	height )

Store the logical monitor size reported by xdg-output.

Parameters

width	Frame or display width in pixels.
height	Frame or display height in pixels.
