/* 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. * * Calls to fetch an X event from the event queue are blocking. Due reading * status text from standard input, a select()-driven main loop has been * implemented which selects for reads on the X connection and STDIN_FILENO to * handle all data smoothly. 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 global * doubly-linked client list, the focus history is remembered through a global * stack list. Each client contains an array of Bools of the same size as the * global tags array to indicate the tags of a client. For each client dwm * creates a small title window, which is resized whenever the (_NET_)WM_NAME * properties are updated or the client is moved/resized. * * 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 /* macros */ #define BUTTONMASK (ButtonPressMask | ButtonReleaseMask) #define CLEANMASK(mask) (mask & ~(numlockmask | LockMask)) #define MOUSEMASK (BUTTONMASK | PointerMotionMask) /* enums */ enum { BarTop, BarBot, BarOff }; /* bar position */ enum { CurNormal, CurResize, CurMove, CurLast }; /* cursor */ enum { ColBorder, ColFG, ColBG, ColLast }; /* color */ enum { NetSupported, NetWMName, NetLast }; /* EWMH atoms */ enum { WMProtocols, WMDelete, WMName, WMState, WMLast };/* default atoms */ /* typedefs */ typedef struct Client Client; struct Client { char name[256]; int x, y, w, h; int rx, ry, rw, rh; /* revert geometry */ int basew, baseh, incw, inch, maxw, maxh, minw, minh; int minax, maxax, minay, maxay; long flags; unsigned int border, oldborder; Bool isbanned, isfixed, ismax, isfloating, wasfloating; Bool *tags; Client *next; Client *prev; Client *snext; Window win; }; typedef struct { int x, y, w, h; unsigned long norm[ColLast]; unsigned long sel[ColLast]; Drawable drawable; GC gc; struct { int ascent; int descent; int height; XFontSet set; XFontStruct *xfont; } font; } DC; /* draw context */ typedef struct { unsigned long mod; KeySym keysym; void (*func)(const char *arg); const char *arg; } Key; typedef struct { const char *symbol; void (*arrange)(void); } Layout; typedef struct { const char *prop; const char *tags; Bool isfloating; } Rule; typedef struct { regex_t *propregex; regex_t *tagregex; } Regs; /* function declarations */ void applyrules(Client *c); void arrange(void); void attach(Client *c); void attachstack(Client *c); void ban(Client *c); void buttonpress(XEvent *e); void checkotherwm(void); void cleanup(void); void compileregs(void); void configure(Client *c); void configurenotify(XEvent *e); void configurerequest(XEvent *e); void destroynotify(XEvent *e); void detach(Client *c); void detachstack(Client *c); void drawbar(void); void drawsquare(Bool filled, Bool empty, unsigned long col[ColLast]); void drawtext(const char *text, unsigned long col[ColLast]); void *emallocz(unsigned int size); void enternotify(XEvent *e); void eprint(const char *errstr, ...); void expose(XEvent *e); void floating(void); /* default floating layout */ void focus(Client *c); void focusnext(const char *arg); void focusprev(const char *arg); Client *getclient(Window w); unsigned long getcolor(const char *colstr); long getstate(Window w); Bool gettextprop(Window w, Atom atom, char *text, unsigned int size); void grabbuttons(Client *c, Bool focused); unsigned int idxoftag(const char *tag); void initfont(const char *fontstr); Bool isoccupied(unsigned int t); Bool isprotodel(Client *c); Bool isvisible(Client *c); void keypress(XEvent *e); void killclient(const char *arg); void leavenotify(XEvent *e); void manage(Window w, XWindowAttributes *wa); void mappingnotify(XEvent *e); void maprequest(XEvent *e); void movemouse(Client *c); Client *nexttiled(Client *c); void propertynotify(XEvent *e); void quit(const char *arg); void resize(Client
