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. + * + * 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 linked client + * list on each monitor, the focus history is remembered through a stack list + * on each monitor. Each client contains a bit 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 <X11/Xatom.h> +#include <X11/Xlib.h> +#include <X11/Xproto.h> +#include <X11/Xutil.h> +#include <X11/cursorfont.h> +#include <X11/keysym.h> +#include <errno.h> +#include <locale.h> +#include <signal.h> +#include <stdarg.h> +#include <stdio.h> +#include <stdlib.h> +#include <string.h> +#include <sys/types.h> +#include <sys/wait.h> +#include <unistd.h> +#ifdef XINERAMA +# include <X11/extensions/Xinerama.h> +#endif /* XINERAMA */ +#include <X11/Xft/Xft.h> +#include <Imlib2.h> +#include "drw.h" +#include "util.h" + +/* macros */ +#define BUTTONMASK (ButtonPressMask | ButtonReleaseMask) +#define CLEANMASK(mask) \ + (mask & ~(numlockmask | LockMask) \ + & (ShiftMask | ControlMask | Mod1Mask | Mod2Mask | Mod3Mask | Mod4Mask | Mod5Mask)) +#define INTERSECT(x, y, w, h, m) \ + (MAX(0, MIN((x) + (w), (m)->wx + (m)->ww) - MAX((x), (m)->wx)) \ + * MAX(0, MIN((y) + (h), (m)->wy + (m)->wh) - MAX((y), (m)->wy))) +#define INTERSECTC(x, y, w, h, z) \ + (MAX(0, MIN((x) + (w), (z)->x + (z)->w) - MAX((x), (z)->x)) \ + * MAX(0, MIN((y) + (h), (z)->y + (z)->h) - MAX((y), (z)->y))) +#define ISVISIBLE(C) ((C->tags & C->mon->tagset[C->mon->seltags])) +#define HIDDEN(C) ((getstate(C->win) == IconicState)) +#define LENGTH(X) (sizeof X / sizeof X[0]) +#define MOUSEMASK (BUTTONMASK | PointerMotionMask) +#define WIDTH(X) ((X)->w + 2 * (X)->bw) +#define HEIGHT(X) ((X)->h + 2 * (X)->bw) +#define TAGMASK ((1 << LENGTH(tags)) - 1) +#define TAGSLENGTH (LENGTH(tags)) +#define TEXTW(X) (drw_fontset_getwidth(drw, (X)) + lrpad) +#define MAXTABS 50 + +#define SYSTEM_TRAY_REQUEST_DOCK 0 + +/* XEMBED messages */ +#define XEMBED_EMBEDDED_NOTIFY 0 +#define XEMBED_WINDOW_ACTIVATE 1 +#define XEMBED_FOCUS_IN 4 +#define XEMBED_MODALITY_ON 10 + +#define XEMBED_MAPPED (1 << 0) +#define XEMBED_WINDOW_ACTIVATE 1 +#define XEMBED_WINDOW_DEACTIVATE 2 + +#define VERSION_MAJOR 0 +#define VERSION_MINOR 0 +#define XEMBED_EMBEDDED_VERSION (VERSION_MAJOR << 16) | VERSION_MINOR + +/* enums */ +enum { + CurNormal, + CurResize, + CurMove, + CurResizeHorzArrow, + CurResizeVertArrow, + CurLast +};
