|
* 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. |
|
* |
|
* Keys and tagging rules are organized as arrays and defined in config.h. |
|
* |
|
* To understand everything else, start reading main(). |
