Classes
class	MirRunner
	Runner for applying initialization options to Mir. More...
class	ApplicationCredentials
class	ApplicationAuthorizer
class	BasicSetApplicationAuthorizer
class	SetApplicationAuthorizer
class	DisplayConfiguration
	Enable display configuration. The config file (miral::MirRunner::display_config_file()) is located via the XDG Base Directory Specification. Vis: ($XDG_CONFIG_HOME or $HOME/.config followed by $XDG_CONFIG_DIRS) More...
class	ExternalClientLauncher
class	Keymap
	Load a keymap. More...
class	SetWindowManagementPolicy
class	StartupInternalClient
	Wrapper for running an internal Mir client at startup. More...
class	InternalClientLauncher
class	WaylandExtensions
	Enable configuration of the Wayland extensions enabled at runtime. More...
class	CanonicalWindowManagerPolicy
	Widely accepted defaults for window management. More...
struct	ApplicationInfo
struct	WindowInfo
class	WindowManagerTools
	Window management functions for querying and updating MirAL's model. More...
struct	WindowManagerOption
class	WindowManagerOptions
class	AppendEventFilter
class	ConfigurationOption
	Add a user configuration option to Mir's option handling. By default the callback will be invoked following Mir initialisation but prior to the server starting. The value supplied to the callback will come from the command line, environment variable, config file or the default. More...
class	CursorTheme
	Load an X-cursor theme, either the supplied default, or through the –cursor-theme config option. More...
class	X11Support
	Add a user configuration option for X11 support. More...
class	MinimalWindowManager
	Minimal implementation of a floating window management policy. More...
class	Window
	Handle class to manage a Mir surface. It may be null (e.g. default initialized) More...
class	WindowSpecification
class	Zone
	A rectangular area of the display. Not tied to a specific output. More...
class	WindowManagementPolicy
	The interface through which the window management policy is determined. More...
class	AddInitCallback
	Add a callback to be invoked when the server has been initialized, but before it starts. If multiple callbacks are added they will be invoked in the sequence added. More...
class	Output
class	PrependEventFilter
class	SetCommandLineHandler
	Set a handler for any command line options Mir/MirAL does not recognise. This will be invoked if any unrecognised options are found during initialisation. Any unrecognised arguments are passed to this function. The pointers remain valid for the duration of the call only. If set_command_line_handler is not called the default action is to exit by throwing mir::AbnormalExit (which will be handled by the exception handler prior to exiting run(). More...
class	SetTerminator
	Set handler for termination requests. terminator will be called following receipt of SIGTERM or SIGINT. The default terminator stop()s the server, replacements should probably do the same in addition to any additional shutdown logic. More...

Detailed Description

Mir Abstraction Layer.

A thin, hopefully ABI stable, layer over the Mir libraries exposing only those abstractions needed to write a shell. One day this may inspire a core Mir library.
