|
|
* Julien's 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 awesome 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. For each client awesome
|
|
* creates a small title window, which is resized whenever the (_NET_)WM_NAME
|
|
* properties are updated or the client is moved/resized.
|
|
*
|
|
* Keys and tagging rules are organized as arrays and defined in the config.h
|
|
* file. These arrays are kept static in event.o and tag.o respectively,
|
|
* because no other part of awesome needs access to them. The current layout is
|
|
* represented by the lt pointer.
|
|
*
|
|
* To understand everything else, start reading main.c:main().
