* 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 a bit array to indicate the tags of a
|
||||
* client.
|
||||
*
|
||||
* Keys and tagging rules are organized as arrays and defined in config.h.
