meillo@754 4 *
meillo@754 5 * dynamic window manager is designed like any other X client as well. It is
meillo@754 6 * driven through handling X events. In contrast to other X clients, a window
meillo@754 7 * manager selects for SubstructureRedirectMask on the root window, to receive
meillo@754 8 * events about window (dis-)appearance. Only one X connection at a time is
meillo@754 9 * allowed to select for this event mask.
meillo@754 10 *
meillo@754 11 * Calls to fetch an X event from the event queue are blocking. Due reading
meillo@754 12 * status text from standard input, a select()-driven main loop has been
meillo@754 13 * implemented which selects for reads on the X connection and STDIN_FILENO to
meillo@754 14 * handle all data smoothly. The event handlers of dwm are organized in an
meillo@754 15 * array which is accessed whenever a new event has been fetched. This allows
meillo@754 16 * event dispatching in O(1) time.
meillo@754 17 *
meillo@754 18 * Each child of the root window is called a client, except windows which have
meillo@754 19 * set the override_redirect flag. Clients are organized in a global
meillo@754 20 * doubly-linked client list, the focus history is remembered through a global
meillo@754 21 * stack list. Each client contains an array of Bools of the same size as the
meillo@754 22 * global tags array to indicate the tags of a client. For each client dwm
meillo@754 23 * creates a small title window, which is resized whenever the (_NET_)WM_NAME
meillo@754 24 * properties are updated or the client is moved/resized.
meillo@754 25 *
meillo@754 26 * Keys and tagging rules are organized as arrays and defined in the config.h
meillo@754 27 * file. These arrays are kept static in event.o and tag.o respectively,
meillo@754 28 * because no other part of dwm needs access to them. The current mode is
meillo@754 29 * represented by the arrange() function pointer, which wether points to
meillo@761 30 * domax() or dotile().
meillo@754 31 *
meillo@754 32 * To understand everything else, start reading main.c:main().
