3 * dynamic window manager is designed like any other X client as well. It is
4 * driven through handling X events. In contrast to other X clients, a window
5 * manager selects for SubstructureRedirectMask on the root window, to receive
6 * events about window (dis-)appearance. Only one X connection at a time is
7 * allowed to select for this event mask.
9 * Calls to fetch an X event from the event queue are blocking. Due reading
10 * status text from standard input, a select()-driven main loop has been
11 * implemented which selects for reads on the X connection and STDIN_FILENO to
12 * handle all data smoothly. The event handlers of dwm are organized in an
13 * array which is accessed whenever a new event has been fetched. This allows
14 * event dispatching in O(1) time.
16 * Each child of the root window is called a client, except windows which have
17 * set the override_redirect flag. Clients are organized in a global
18 * doubly-linked client list, the focus history is remembered through a global
19 * stack list. Each client contains an array of Bools of the same size as the
20 * global tags array to indicate the tags of a client.
22 * Keys and tagging rules are organized as arrays and defined in config.h.
24 * To understand everything else, start reading main().
