Garbe +/* © 2006-2007 Anselm R. Garbe + * © 2006-2007 Sander van Dijk * See LICENSE file for license details. + * + * dynamic window manager is designed like any other X client as well. It is + * driven through handling X events. In contrast to other X clients, a window + * manager selects for SubstructureRedirectMask on the root window, to receive + * events about window (dis-)appearance. Only one X connection at a time is + * allowed to select for this event mask. + * + * Calls to fetch an X event from the event queue are blocking. Due reading + * status text from standard input, a select()-driven main loop has been + * implemented which selects for reads on the X connection and STDIN_FILENO to + * handle all data smoothly. The event handlers of dwm are organized in an + * array which is accessed whenever a new event has been fetched. This allows + * event dispatching in O(1) time. + * + * Each child of the root window is called a client, except windows which have + * set the override_redirect flag. Clients are organized in a global + * doubly-linked client list, the focus history is remembered through a global + * stack list. Each client contains an array of Bools of the same size as the + * global tags array to indicate the tags of a client. For each client dwm + * creates a small title window, which is resized whenever the (_NET_)WM_NAME + * properties are updated or the client is moved/resized. + * + * Keys and tagging rules are organized as arrays and defined in the config.h + * file. These arrays are kept static in event.o and tag.o respectively, + * because no other part of dwm needs access to them. The current layout is + * represented by the lt pointer. + * + * To understand everything else, start reading main.c:main(). */ +#include "config.h" #include -/********** CUSTOMIZE **********/ +/* mask shorthands, used in event.c and client.c */ +#define BUTTONMASK (ButtonPressMask | ButtonReleaseMask) -#define FONT "-*-terminus-medium-*-*-*-13-*-*-*-*-*-iso10646-*" -#define BGCOLOR "#0a2c2d" -#define FGCOLOR "#ddeeee" -#define BORDERCOLOR "#176164" -#define MODKEY Mod1Mask /* Mod4Mask */ -/* -#define BGCOLOR "#666699" -#define FGCOLOR "#eeeeee" -#define BORDERCOLOR "#9999CC" -*/ -#define MASTERW 52 /* percent */ -#define WM_PROTOCOL_DELWIN 1 +enum { NetSupported, NetWMName, NetLast };
