When monitors are removed, the coordinates of existing monitors may change, if the removed monitors had smaller coordinates than the remaining ones. Remove special case handling so that the same update-if-necessary loop is run also in the case when monitors are removed.

|
|
* 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().
