/* See LICENSE file for copyright and license details. * * dynamic window manager is designed like any other X client as well. 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 #ifdef XINERAMA #include #endif /* XINERAMA */ #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_fontset_getwidth(drw, (X)) + lrpad) #define OPAQUE 0xffU /* enums */ enum { CurNormal, CurResize, CurMove, CurSwal, CurLast }; /* cursor */ enum { SchemeNorm, SchemeSel, SchemeHigh }; /* color schemes */ enum { NetSupported, NetWMName, NetWMState, NetWMCheck, NetWMFullscreen, NetActiveWindow, NetWMWindowType, NetWMWindowTypeDialog, NetClientList, NetLast }; /* EWMH atoms */ enum { WMProtocols, WMDelete, WMState, WMTakeFocus, WMLast }; /* default atoms */ enum { ClkTagBar, ClkLtSymbol, ClkStatusText, ClkWinTitle, ClkClientWin, ClkRootWin, ClkLast }; /* clicks */ enum { ClientRegular = 1, ClientSwallowee, ClientSwallower }; /* client types */ typedef union { int i; unsigned int ui; float f; const void *v; } Arg; typedef struct { unsigned int click; unsigned int mask; unsigned int button; void (*func)(const Arg *arg); const Arg arg; } Button; typedef struct Monitor Monitor; typedef struct Client Client; struct Client { char name[256]; float mina, maxa; int x, y, w, h; int oldx, oldy, oldw, oldh; int basew, baseh, incw, inch, maxw, maxh, minw, minh, hintsvalid; int bw, oldbw; unsigned int tags; int isfixed, isfloating, isurgent, neverfocus, oldstate, isfullscreen; Client *next; Client *snext; Client *swer; /* swallower of client, NULL by default */ Monitor *mon; Window win; }; typedef struct { unsigned int mod; KeySym keysym; void (*func)(const Arg *); const Arg arg; } Key; typedef struct { const char *symbol; void (*arrange)(Monitor *); } Layout; struct Monitor { char ltsymbol[16]; float mfact; int nmaster; int num; int by; /* bar geometry */ int mx, my, mw, mh; /* screen size */ int wx, wy, ww, wh; /* window area */ int gappih; /* horizontal gap between windows */ int gappiv; /* vertical gap between windows */ int gappoh; /* horizontal outer gaps */ int gappov; /* vertical outer gaps */ unsigned int seltags; unsigned int sellt; unsigned int tagset[2]; int showbar; int topbar; Client *clients; Client *sel; Client *stack; Monitor *next; Window barwin; const Layout *lt[2]; }; typedef struct { const char *class; const char *instance; const char *title; unsigned int tags; int isfloating; int monitor; } Rule; typedef struct Swallow Swallow; struct Swallow { /* Window class name, instance name (WM_CLASS) and title * (WM_NAME/_NET_WM_NAME, latter preferred if it exists).
