* |
|
* 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(). |
