1 /* See LICENSE file for copyright and license details. 2 * 3 * dynamic window manager is designed like any other X client as well. It is 4 * driven through handling X events. In contrast to other X clients, a window 5 * manager selects for SubstructureRedirectMask on the root window, to receive 6 * events about window (dis-)appearance. Only one X connection at a time is 7 * allowed to select for this event mask. 8 * 9 * The event handlers of dwm are organized in an array which is accessed 10 * whenever a new event has been fetched. This allows event dispatching 11 * in O(1) time. 12 * 13 * Each child of the root window is called a client, except windows which have 14 * set the override_redirect flag. Clients are organized in a linked client 15 * list on each monitor, the focus history is remembered through a stack list 16 * on each monitor. Each client contains a bit array to indicate the tags of a 17 * client. 18 * 19 * Keys and tagging rules are organized as arrays and defined in config.h. 20 * 21 * To understand everything else, start reading main(). 22 */ 23 #include <errno.h> 24 #include <locale.h> 25 #include <signal.h> 26 #include <stdarg.h> 27 #include <stdio.h> 28 #include <stdlib.h> 29 #include <string.h> 30 #include <unistd.h> 31 #include <sys/types.h> 32 #include <sys/wait.h> 33 #include <X11/cursorfont.h> 34 #include <X11/keysym.h> 35 #include <X11/Xatom.h> 36 #include <X11/Xlib.h> 37 #include <X11/Xproto.h> 38 #include <X11/Xutil.h> 39 #ifdef XINERAMA 40 #include <X11/extensions/Xinerama.h> 41 #endif /* XINERAMA */ 42 #include <X11/Xft/Xft.h> 43 #include <fcntl.h> 44 45 #include "drw.h" 46 #include "util.h" 47 48 /* macros */ 49 #define BUTTONMASK (ButtonPressMask|ButtonReleaseMask) 50 #define CLEANMASK(mask) (mask & ~(numlockmask|LockMask) & (ShiftMask|ControlMask|Mod1Mask|Mod2Mask|Mod3Mask|Mod4Mask|Mod5Mask)) 51 #define INTERSECT(x,y,w,h,m) (MAX(0, MIN((x)+(w),(m)->wx+(m)->ww) - MAX((x),(m)->wx)) \ 52 * MAX(0, MIN((y)+(h),(m)->wy+(m)->wh) - MAX((y),(m)->wy))) 53 #define ISVISIBLE(C) ((C->tags & C->mon->tagset[C->mon->seltags])) 54 #define LENGTH(X) (sizeof X / sizeof X[0]) 55 #define MOUSEMASK (BUTTONMASK|PointerMotionMask) 56 #define WIDTH(X) ((X)->w + 2 * (X)->bw) 57 #define HEIGHT(X) ((X)->h + 2 * (X)->bw) 58 #define TAGMASK ((1 << LENGTH(tags)) - 1) 59 #define TEXTW(X) (drw_fontset_getwidth(drw, (X)) + lrpad) 60 #define TTEXTW(X) (drw_fontset_getwidth(drw, (X))) 61 62 #define DWMBLOCKSLOCKFILE "/tmp/dwmblocks.pid" 63 64 65 /* enums */ 66 enum { CurNormal, CurHand, CurResize, CurMove, CurLast };
