|
4 * dynamic window manager is designed like any other X client as well. It is
|
|
arg@457
|
5 * driven through handling X events. In contrast to other X clients, a window
|
|
arg@468
|
6 * manager selects for SubstructureRedirectMask on the root window, to receive
|
|
arg@468
|
7 * events about window (dis-)appearance. Only one X connection at a time is
|
|
arg@468
|
8 * allowed to select for this event mask.
|
|
arg@457
|
9 *
|
|
arg@468
|
10 * Calls to fetch an X event from the event queue are blocking. Due reading
|
|
arg@469
|
11 * status text from standard input, a select()-driven main loop has been
|
|
arg@468
|
12 * implemented which selects for reads on the X connection and STDIN_FILENO to
|
|
arg@468
|
13 * handle all data smoothly. The event handlers of dwm are organized in an
|
|
arg@468
|
14 * array which is accessed whenever a new event has been fetched. This allows
|
|
arg@468
|
15 * event dispatching in O(1) time.
|
|
arg@457
|
16 *
|
|
arg@460
|
17 * Each child of the root window is called a client, except windows which have
|
|
arg@460
|
18 * set the override_redirect flag. Clients are organized in a global
|
|
arg@460
|
19 * doubly-linked client list, the focus history is remembered through a global
|
|
arg@460
|
20 * stack list. Each client contains an array of Bools of the same size as the
|
|
arg@460
|
21 * global tags array to indicate the tags of a client. For each client dwm
|
|
arg@468
|
22 * creates a small title window, which is resized whenever the (_NET_)WM_NAME
|
|
arg@468
|
23 * properties are updated or the client is moved/resized.
|
|
arg@457
|
24 *
|
|
arg@459
|
25 * Keys and tagging rules are organized as arrays and defined in the config.h
|
|
arg@459
|
26 * file. These arrays are kept static in event.o and tag.o respectively,
|
|
arg@459
|
27 * because no other part of dwm needs access to them. The current mode is
|
|
arg@469
|
28 * represented by the arrange() function pointer, which wether points to
|
|
arg@469
|
29 * dofloat() or dotile().
|
|
arg@457
|
30 *
|
|
arg@468
|
31 * To understand everything else, start reading main.c:main().
