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 -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#ifdef XINERAMA -#include -#endif /* XINERAMA */ -#include -#include -#include -#ifdef __OpenBSD__ -#include -#include -#endif /* __OpenBSD */ - -#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 ISVISIBLE(C) ((C->tags & C->mon->tagset[C->mon->seltags])) -#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 NUMTAGS (LENGTH(tags) + LENGTH(scratchpads)) -#define TAGMASK ((1 << NUMTAGS) - 1) -#define SPTAG(i) ((1 << LENGTH(tags)) << (i)) -#define SPTAGMASK (((1 << LENGTH(scratchpads)) - 1) << LENGTH(tags)) -#define TEXTW(X) (drw_fontset_getwidth(drw, (X)) + lrpad) - -#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, CurLast };
