*
|
||
* 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.
|
||
*
|
||
* 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 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().
