It is meillo@754: * driven through handling X events. In contrast to other X clients, a window meillo@754: * manager selects for SubstructureRedirectMask on the root window, to receive meillo@754: * events about window (dis-)appearance. Only one X connection at a time is meillo@754: * allowed to select for this event mask. meillo@754: * meillo@754: * Calls to fetch an X event from the event queue are blocking. Due reading meillo@754: * status text from standard input, a select()-driven main loop has been meillo@754: * implemented which selects for reads on the X connection and STDIN_FILENO to meillo@754: * handle all data smoothly. The event handlers of dwm are organized in an meillo@754: * array which is accessed whenever a new event has been fetched. This allows meillo@754: * event dispatching in O(1) time. meillo@754: * meillo@754: * Each child of the root window is called a client, except windows which have meillo@754: * set the override_redirect flag. Clients are organized in a global meillo@754: * doubly-linked client list, the focus history is remembered through a global meillo@754: * stack list. Each client contains an array of Bools of the same size as the meillo@754: * global tags array to indicate the tags of a client. For each client dwm meillo@754: * creates a small title window, which is resized whenever the (_NET_)WM_NAME meillo@754: * properties are updated or the client is moved/resized. meillo@754: * meillo@754: * Keys and tagging rules are organized as arrays and defined in the config.h meillo@754: * file. These arrays are kept static in event.o and tag.o respectively, meillo@754: * because no other part of dwm needs access to them. The current mode is meillo@754: * represented by the arrange() function pointer, which wether points to meillo@754: * dofloat() or dotile(). meillo@754: * meillo@754: * To understand everything else, start reading main.c:main(). garbeam@0: */ garbeam@0: meillo@754: #include "config.h" garbeam@59: #include arg@619: #include meillo@754: #include garbeam@0: #include meillo@754: #include garbeam@0: #include garbeam@57: #include garbeam@59: #include arg@138: #include meillo@754: #include meillo@754: #include garbeam@0: #include arg@291: #include garbeam@0: #include meillo@754: #include garbeam@0: #include meillo@754: #include garbeam@0: meillo@754: /* mask shorthands, used in event.c and client.c */ meillo@754: #define BUTTONMASK (ButtonPressMask | ButtonReleaseMask) arg@333: meillo@754: enum { NetSupported, NetWMName, NetLast };
