miawm (mathIsART window manager) is a minimalistic, keyboard-only, tiling window manager for the X Window System (aka. X11) in C + xcb.
miawm subscribes to the Unix philosophy (do one thing, and do it well), and considers that a window manager must do exactly 2 things:
- manage windows (move, resize, hide)
- implement universal shortcuts (mostly for launching/closing applications, and changing the window focus)
In particular, a window manager must not:
- reparent top-level windows (or any window)
- draw window frames
- draw window decorations/buttons/titlebars/menus
- draw application menus (an exception is the menu that has the list of all the windows)
- have anything to do whatsoever with drawing UI elements
- have anything to do whatsoever with compositing (ie. the so-called "compositing" window managers are an oxymoron; a "compositing window manager" is not a window manager, but a chimeric abomination)
- dishonor application position/size requests sent via
@xcb_create_window()
A good window manager is an invisible window manager.
A window manager must get out of the way as much as possible.
It follows that window managers are naturally very simple applications, and require very little code.
The logic for a window manager is very shallow and the responsibilities few, and so its code must be very shallow (and small) as well.

xcb has almost no formal documentation.
So, its best "documentation" is the source code itself.
However, most of the source code is machine-generated from a description of the X Protocol.
So, the source code is only useful as documentation if you understand what xcb is.
xcb is a thin wrapper around the X Protocol.
So, in order to understand xcb, you must understand the X Protocol (not deeply though, but only at a high level).
The X Protocol is just a specification for sending/receiving packets ("messages") between a "client" and a "server" (think http, but for graphics instructions).
The X Protocol is a request-reply-error-event protocol, meaning that every packet ("message") between the "client" and the "server" is a request, or a reply, or an error, or an event.
If you understand the X Protocol well enough, you can open your own socket() into the X server and send requests and receive replies/errors/events on your own, without xlib or xcb. (This is easier than it sounds.)
Another good piece of xcb documentation is, paradoxically, xlib documentation.
Once you understand that xlib is a high-level wrapper (that destroys much of the X Protocols semantics by hiding low-level X Protocol details) and that xcb is a low-level wrapper, you can (with some effort) "translate" between xlib functions and xcb functions.
xlib documentation is good for xcb because a lot of the xlib documentation actually explains X Protocol details, and that's useful for both xlib and xcb.
In xcb there are 3 kinds of API entry points: xcb_<op>(), xcb_<op>_checked(), xcb_<op>_unchecked().
xcb_<op>_checked() API calls return: xcb_void_cookie_t.
xcb_<op>_unchecked() API calls return: xcb_<op>_cookie_t.
xcb_<op>() API calls return: xcb_void_cookie_t if xcb_<op>_checked() exists, and xcb_<op>_cookie_t if xcb_<op>_unchecked() exists.
Both xcb_void_cookie_t and xcb_<op>_cookie_t are a struct{ unsigned int sequence; };, so they can be processed by the same error-checking macro.
Example API entry points.
xcb_void_cookie_t xcb_create_window();
xcb_void_cookie_t xcb_create_window_checked();
xcb_get_window_attributes_cookie_t xcb_get_window_attributes();
xcb_get_window_attributes_cookie_t xcb_get_window_attributes_unchecked();For requests with no reply (eg. xcb_map_window()), errors are delivered to the event loop (you receive an X11 event of type 0x00 when calling xcb_poll_for_event()). In order to explicitly check for errors in a BLOCKING fashion, call xcb_<op>_checked() (eg. xcb_map_window_checked()) and use xcb_request_check().
For requests with a reply (eg. xcb_intern_atom()), errors are checked when calling the reply function. To get errors in the event loop instead, call xcb_<op>_unchecked() (eg. xcb_intern_atom_unchecked()).
Let W be a window.
Let idx[W be the index (aka. position) of window W in the window stack.
Let map_state[W] be the map state of window W.
wm_focus_next(@idx) focuses the window W (in the window stack) satisfying:
0) idx[W] is not @idx
1) map_state[W] is XCB_MAP_STATE_VIEWABLE
2) IF there exists a viewable window X (in the window stack) satisfying idx[X] > @idx (ie. the upper-viewable chain at @idx is nonempty), THEN W satisfies: for all windows X satisfying idx[X] > @idx, we have that idx[W] <= idx[X] (ie. idx[W] is the minimum of the upper-viewable chain at @idx)
3) IF there doesn't exist a viewable window X (in the window stack) satisfying idx[X] > @idx (ie. the upper-viewable chain at @idx is empty), THEN
IF there exists a viewable window X (in the window stack) satisfying idx[X] < @idx [ie. the lower-viewable chain at @idx is nonempty), THEN W satisfies: for all windows X satisfying idx[X] < @idx, we have that idx[W] >= idx[X] (ie. idx[W] is the maximum of the lower-viewable chain at @idx)
4) IF there doesn't exist a viewable window X (in the window stack) satisfying idx[X] > @idx (ie. the upper-viewable chain at @idx is empty), THEN
IF there doesn't exists a viewable window X (in the window stack) satisfying idx[X] < @idx [ie. the lower-viewable chain at @idx is empty), THEN W is the VOID window (ie. idx[W] is 0x00000000)

ACTIVE GRABS (invoked by calling XGrabPointer() or XGrabKeyboard()) causes pointer and keyboard events to be sent to the grabbing window.
PASSIVE GRABS (invoked by calling XGrabKey() or XGrabButton()) causes an ACTIVE GRAB to begin when a certain key or button combination is pressed.
PASSIVE GRABS are useful in implementing menus.
When you grab a device, you have the option of confining the pointer to any window within the grabbing client and of controlling the further processing of both keyboard and pointer events.
Grabbing the keyboard effectively selects all keyboard events, whether you selected them previously or not.
Grabbing the keyboard also causes FocusIn and FocusOut events to be sent to the old and new focus windows, but they must be selected by each window to be received.
In the call to grab the pointer, however, you specify what types of pointer, button, and enter/leave events you want.
Grabs take precedence over the keyboard focus window. Grabs of the keyboard generated FocusIn and FocusOut events, so that if your client selects these, it can determine whether or not it can get keyboard events.
Pointer grabbing is more problematic, since no event notifies other clients when one client has grabbed it. However, pointer grabs are almost always temporary.

xcb_grab_key()
Passive grab on the keyboard. In the future, the keyboard is actively grabbed (as for GrabKeyboard), the last-keyboard-grab time is set to the time at which the key was pressed (as transmitted in the KeyPress event), and the KeyPress event is reported if all of the following conditions are true:
The keyboard is not grabbed and the specified key (which can itself be a modifier key) is logically pressed when the specified modifier keys are logically down, and no other modifier keys are logically down.
Either the grab_window is an ancestor of (or is) the focus window, or the grab_window is a descendant of the focus window and contains the pointer.
A passive grab on the same key combination does not exist on any ancestor of grab_window.
The interpretation of the remaining arguments is as for XGrabKeyboard. The active grab is terminated automatically when the logical state of the keyboard has the specified key released (independent of the logical state of the modifier keys), at which point a KeyRelease event is reported to the grabbing window.
Note that the logical state of a device (as seen by client apps) may lag the physical state if device event processing is frozen.
A modifiers argument of AnyModifier is equivalent to issuing the request for all possible modifier combinations (including the combination of no modifiers). It is not required that all modifiers specified have currently assigned KeyCodes. A keycode argument of AnyKey is equivalent to issuing the request for all possible KeyCodes. Otherwise, the specified keycode must be in the range specified by min_keycode and max_keycode in the connection setup, or a BadValue error results.
If some other client has issued a XGrabKey with the same key combination on the same window, a BadAccess error results. When using AnyModifier or AnyKey, the request fails completely, and a BadAccess error results (no grabs are established) if there is a conflicting grab for any combination.

XCB_GRAB_ANY: Grab any key
XCB_GRAB_MODE_SYNC: The state of the keyboard appears to freeze: No further keyboard events are generated by the server until the grabbing client issues a releasing AllowEvents request or until the keyboard grab is released

X allows you to control which physical keys are considered modifier keys.
Like keycode-to-keysym remapping, this can be done by an app run from the user’s startup script (eg. xmodmap).
Modifier keys generate KeyPress and KeyRelease events like other keys, but they are the only keys reported in the state member of every key, button, motion, or border-crossing event.
The state member is a mask that indicates which logical modifiers were pressed when the event occurred. Each bit in state is represented by a constant such as ControlMask.
state is used by XLookupString() to generate the correct keysym from a key event.
Note that the state member of events other than key, button, motion, and border-crossing events does not have the meaning described here.
-- The Xlib Programming Manual
https://tronche.com/gui/x/icccm/sec-6.html#s-6
X Version 11 supports eight modifier bits of which three are preassigned to Shift, Lock, and Control. Each modifier bit is controlled by the state of a set of keys, and these sets are specified in a table accessed by GetModifierMapping and SetModifierMapping requests. This table is a shared resource and requires conventions.
A client that needs to use one of the preassigned modifiers should assume that the modifier table has been set up correctly to control these modifiers. The Lock modifier should be interpreted as Caps Lock or Shift Lock according as the keycodes in its controlling set include XK_Caps_Lock or XK_Shift_Lock.
Convention
Clients should determine the meaning of a modifier bit from the KeySyms being used to control it.
A client that needs to use an extra modifier (for example, META) should do the following:
Scan the existing modifier mappings. If it finds a modifier that contains a keycode whose set of KeySyms includes XK_Meta_L or XK_Meta_R, it should use that modifier bit.
If there is no existing modifier controlled by XK_Meta_L or XK_Meta_R, it should select an unused modifier bit (one with an empty controlling set) and do the following:
If there is a keycode with XL_Meta_L in its set of KeySyms, add that keycode to the set for the chosen modifier.
If there is a keycode with XL_Meta_R in its set of KeySyms, add that keycode to the set for the chosen modifier.
If the controlling set is still empty, interact with the user to select one or more keys to be META.
If there are no unused modifier bits, ask the user to take corrective action.
Conventions
Clients needing a modifier not currently in use should assign keycodes carrying suitable KeySyms to an unused modifier bit. Clients assigning their own modifier bits should ask the user politely to remove his or her hands from the key in question if their SetModifierMapping request returns a Busy status.
There is no good solution to the problem of reclaiming assignments to the five nonpreassigned modifiers when they are no longer being used.
Convention
The user must use xmodmap or some other utility to deassign obsolete modifier mappings by hand.
When a client succeeds in performing a SetModifierMapping request, all clients will receive MappingNotify (request==Modifier) events. There is no mechanism for preventing these events from being received. A client that uses one of the nonpreassigned modifiers that receives one of these events should do a GetModifierMapping request to discover the new mapping, and if the modifier it is using has been cleared, it should reinstall the modifier.
Note that a GrabServer request must be used to make the GetModifierMapping and SetModifierMapping pair in these transactions atomic.

Window managers almost always place in the save-set all the windows they reparent or iconify, using XAddToSaveSet().
Windows are automatically removed from the save-set when they are destroyed.
If your window manager doesn't not reparent/iconify (which should ALWAYS be the case), then it doesn't need a save set.

xprop -root "Wacom Serial IDs"This topic describes EGL mechanisms that you can use to implement a pure EGL display. Such a display does not use a window system.
EGLDevice provides a mechanism to access graphics functionality in the absence of or without reference to a native window system. It is a method to initialize EGL displays and surfaces directly on top of GPUs/devices rather than native window system objects. It is a cross-platform method to discover media devices like displays, GPUs, etc. The set of EGLDevice extensions boot strap EGL, without the use of any native APIs.
EGLOutput is to graphical outputs what EGLDevice is to devices. It allows enumeration of outputs on a device. EGLOutput allows rendering directly to a screen in the absence of a window system. Additionally, it allows apps to bypass native window systems for direct rendering. It defines certain EGL resources for referencing display control hardware associated with an EGL device. EGLOutput provides a binding between GL, NVIDIA® CUDA®, and multimedia rendering and the display output. In a typical Embedded setting, the outputs are often initialized to a fixed state at system startup. But in cases where they are configurable, other interfaces such as DRM must be used.
EGLStream is a mechanism to share data efficiently between different APIs without copying data. APIs could be OpenGL, CUDA, Multimedia, etc. A producer and a consumer are attached to two ends of a stream object:
- Producer adds content into the stream.
- Consumer retrieves this content.
EGLOutput instances can also be specified as consumers, allowing APIs to direct their output to the screen.
