  3. * dynamic window manager is designed like any other X client as well. It is
  4. * driven through handling X events. In contrast to other X clients, a window
  5. * manager selects for SubstructureRedirectMask on the root window, to receive
  6. * events about window (dis-)appearance. Only one X connection at a time is
  7. * allowed to select for this event mask.
  8. *
  9. * The event handlers of dwm are organized in an array which is accessed
  10. * whenever a new event has been fetched. This allows event dispatching
  11. * in O(1) time.
  12. *
  13. * Each child of the root window is called a client, except windows which have
  14. * set the override_redirect flag. Clients are organized in a linked client
  15. * list on each monitor, the focus history is remembered through a stack list
  16. * on each monitor. Each client contains a bit array to indicate the tags of a
  17. * client.
  18. *
  19. * Keys and tagging rules are organized as arrays and defined in config.h.
  20. *
  21. * To understand everything else, start reading main().
