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 <X11/Xlib.h> - -/* mask shorthands, used in event.c and client.c */ -#define BUTTONMASK (ButtonPressMask | ButtonReleaseMask) - -enum { BarTop, BarBot, BarOff };
