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 "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 TAGMASK ((1 << LENGTH(tags)) - 1) -#define TEXTW(X) (drw_font_getwidth(drw, (X), False) + lrpad) -#define TEXTWM(X) (drw_font_getwidth(drw, (X), True) + lrpad) - -/* enums */ -enum { CurNormal, CurResize, CurMove, CurLast };
