/* See LICENSE file for copyright and license details. * * Polytree tiling 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 PolytreeWM 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 #ifdef XINERAMA #include #endif /* XINERAMA */ #include #include #include #ifdef __OpenBSD__ #include #include #endif /* __OpenBSD */ #include "atoms.h" #include "drw.h" #include "helpers.h" #include "layouts.h" #include "menu.h" #include "settings.h" #include "spawn.h" #include "tags.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 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 /********* * types * *********/ enum { CurNormal, CurResize, CurMove, CurLast };
