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. + * + * Keys and tagging rules are organized as arrays and defined in config.h. + * + * To understand everything else, start reading main(). + */ #include #include -#include #include #include #include #include #include #include +#include #include +#include #include #include #include +#include #include #include +//#ifdef XINERAMA +#include +//#endif /* macros */ #define BUTTONMASK (ButtonPressMask | ButtonReleaseMask) #define CLEANMASK(mask) (mask & ~(numlockmask | LockMask)) +#define LENGTH(x) (sizeof x / sizeof x[0]) +#define MAXTAGLEN 16 #define MOUSEMASK (BUTTONMASK | PointerMotionMask) + /* enums */ enum { BarTop, BarBot, BarOff };
