-Introduction
-============
-
-The LibWindowmanager library provides a simple interface to manipulate and
-query the state of the window manager application framework binding.
-It is needs to be integrated and called from the client application.
-
-Intended audience
------------------
-
-This document is intended to be useful to application developers.
-
-Scope of this Document
-----------------------
-
-This document describes the singleton class interface to the *Window
-Manager* binding service.
-
-class LibWindowmanager
-===============
-
-This is the public interface of the class `LibWindowmanager`. Private members
-and methods are not reproduced as they will not affect usage of the
-class by client applications.
-
- class LibWindowmanager
- {
- public:
- static LibWindowmanager &instance();
-
- int init(int port, char const *token);
-
- // WM API
- int requestSurface(const char *label);
- int activateSurface(const char *label);
- int deactivateSurface(const char *label);
- int endDraw(const char *label);
-
- enum EventType {
- Event_Active,
- Event_Inactive,
- Event_Visible,
- Event_Invisible,
- Event_SyncDraw,
- Event_FlushDraw,
- };
-
- void set_event_handler(enum EventType et,
- std::function<void(char const *label)> f);
- };
-
-Errors
-------
-
-Methods returning an `int` signal successful operation when returning
-`0`. In case of an error, an error value is returned as a negative errno
-value. E.g. `-EINVAL` to signal that some input value was invalid.
-
-Additionally, logging of error messages is done on the standard error
-file descriptor to help debugging the issue.
-
-Labels
-------
-
-Surface labels are any valid strings. For `requestSurface()` these
-strings must match the *Window Manager* configuration in order to be
-allowed to be displayed on one layer or the other. For all other calls
-the label must match the exact name of a requested surface.
-
-Methods
--------
-
-### LibWindowmanager::init(port, token)
-
-Initialize the Binding communication.
-
-The `token` parameter is a string consisting of only alphanumeric characters.
-If these conditions are not met, the LibWindowmanager instance will not initialize,
-i.e. this call will return `-EINVAL`.
-
-The `port` parameter is the port the afb daemon is listening on, an
-invalid port will lead to a failure of the call and return `-EINVAL`.
-
-### LibWindowmanager::requestSurface(label)
-
-This method requests a surface with the label given from the *Window
-Manager*. It will return `0` for a successful surface request, and
-`-errno` on failure. Additionally, on the standard error, messages are
-logged to help debgging the issue.
-
-### LibWindowmanager::activateSurface(label)
-
-This method is mainly intended for *manager* applications that control
-other applications (think an application manager or the *HomeScreen*).
-It instructs the window manager to activate the surface with the given
-*label*.
-
-This method only is effective after the actual window or surface was
-created by the application.
-
-### LibWindowmanager::deactivateSurface(label)
-
-This method is mainly intended for *manager* applications that control
-other applications. It instructs the window manager to deactivate the
-surface associated with the given label. Note, that deactivating a
-surface also means to implicitly activate another (the last active or if
-not available *main surface* or *HomeScreen*.)
-
-This method only is effective after the actual window or surface was
-created by the application.
-
-### LibWindowmanager::endDraw(label)
-
-This function is called from a client application when it is done
-drawing its surface content.
-
-It is not crucial to make this call at every time a drawing is finished
-- it is mainly intended to allow the window manager to synchronize
-drawing in case of layout switch. The exact semantics are explained in
-the next [Events](#_events) Section.
-
-### LibWindowmanager::set\_event\_handler(et, func)
-
-This method needs to be used to register event handlers for the WM
-events described in the EventType enum. Only one hendler for each
-EventType is possible, i.e. if it is called multiple times with the same
-EventType the previous handler will be replaced.
-
-The `func` handler functions will receive the label of the surface this
-event is targeted at.
-
-See Section [Events](#_events) for mor detailed information about event
-delivery to client applications.
-
-Usage
------
-
-### Initialization of LibWindowmanager
-
-Before usage of the LibWindowmanager, the method `init()` must be
-called once, it will return `-errno` in case of en error and log
-diagnostic messages to stderr.
-
-### Request a surface
-
-When creating a surface with *Qt* - it is necessary to request a surface
-from the WM, internally this will communicate with the window manager
-binding. Only after `requestSurface()` was successful, a surface should
-be created.
-
-This is also true for *QML* aplications, where only after the
-`requestSurface()` should the load of the resource be done. The method
-returns `0` after the surface was requested successfully.
-
-#### Workings of requestSurface()
-
-`LibWindowmanager::requestSurface()` calls the AFB binding verb
-`requestsurface` of the `windowmanager` API. This API call will return a
-numeric ID to be used when creating the surface. This ID is never
-explicitly returned to the client application, instead, it is set in the
-application environment in order for *Qt* to then use it when creating
-the surface.
-
-With the current *Qt* implementation this means, that only one surface
-will be available to client applications, as subsequent windows will
-increment this numeric ID internally - which then will lead to IDs that
-cannot be known by the window manager as there is no direct
-communication from *Qt* to the WM.
-
-Events
-------
-
-Events are a way for the *Window Manager* to propagate information to
-client applications. It was vital for the project to implement a number
-of events, that mirror functionality that is already present in the
-wayland protocol.
-
-All events have the surface `label` as argument - a way to enable future
-multi-surface applications.
-
-As already stated above, this is currently not possible with the way
-*Qt* implements its surface ID setting.
-
-### Active and Inactive Events
-
-These events signal an application that it was activated or deactivated
-respectively. Usually this means it was switched visible - which means
-the surface will now be on the screen and therefor continue to render.
-
-### Visible and Invisible
-
-These events signal an application that it was switched to be visible or
-invisible respectively. These events too are handled implicitly through
-the wayland protocol by means of `wl_surface::enter` and
-`wl_surface::leave` events to the client.
-
-### SyncDraw and FlushDraw
-
-These events instruct applications that they should redraw their surface
-contents - again, this is handled implicitly by the wayland protocol.
-
-`SyncDraw` is sent to the application when it has to redraw its surface.
-
-`FlushDraw` is sent to the application when it should swap its buffers,
-that is *signal* the compositor that its surface contains new content.
-
-Example Use Case
-----------------
-
-In order to enable application to use the `WM` surface registration
-function the above described steps need to be implemented.
-
-As a minimal example the usage and initialization can look like the
-following.
-
- // Assume a program argc and argv.
- QGuiApplication app(argc, argv);
-
- auto &wm = LibWindowmanager::instance();
-
- // initialize the LibWindowmanager binding.
- if(wm.init(1234, "wmtest") != 0) {
- exit(EXIT_FAILURE);
- }
-
- // Request a surface label from the WM.
- char const *surface_label = "AppMediaPlayer";
- if (wm.requestSurface(surface_label) != 0) {
- exit(EXIT_FAILURE);
- }
-
- // Register an Active event handler.
- wm.set_event_handler(Event_Active,
- [](char const *label) {
- qDebug() << "Surface" << label << "got activated";
- });
-
- // Initialize application window
- // ...
-
- // request to activate the surface, this should usually
- // not be done by the client application.
- if (wm.activateSurface(surface_label) != 0) {
- fprintf(stderr, "Could not activate the surface\n");
- exit(EXIT_FAILURE);
- }
-
- // e.g. exec the qt application
- app.exec();
