+ * | |
+ * 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 the config.h | |
+ * file. These arrays are kept static in event.o and tag.o respectively, | |
+ * because no other part of dwm needs access to them. The current layout is | |
+ * represented by the lt pointer. | |
+ * | |
+ * To understand everything else, start reading main(). | |
