-.TH GRIDMENU 1 grid-0.0
-.SH NAME
-gridmenu \- grid window manager menu
-.SH SYNOPSIS
-.B gridmenu
-.RB [ \-v ]
-.RB [ \-t
-.IR title ]
-.SH DESCRIPTION
-.SS Overview
-.B gridmenu
-is a generic, highly customizable, and efficient menu for the X Window System,
-originally designed for
-.BR grid (1).
-It supports arbitrary, user defined menu contents.
-.SS Options
-.TP
-.B \-v
-prints version information to stdout, then exits.
-.TP
-.BI \-t " title"
-displays
-.I title
-above the menu.
-.SS Usage
-.B gridmenu
-reads a list of newline-separated items from stdin and creates a menu.
-When the user selects an item or enters any text and presses Enter, his choice
-is printed to stdout and
-.B gridmenu
-terminates.
-.SS Keyboard Control
-.B gridmenu
-is completely controlled by the keyboard. The following keys are recognized:
-.TP 2
-Any printable character
-appends the character to the text in the input field. This works as a filter:
-only items containing this text will be displayed.
-.TP 2
-Left/Right (Control-p/Control-n)
-select the previous/next item.
-.TP 2
-Tab (Control-i)
-copy the selected item to the input field.
-.TP 2
-Enter (Control-j)
-confirm selection and quit (print the selected item to stdout).
-.TP 2
-Shift-Enter (Shift-Control-j)
-confirm selection and quit (print the text in the input field to stdout).
-.TP 2
-Escape (Control-[)
-quit without selecting an item.
-.TP 2
-Backspace (Control-h)
-remove enough characters from the input field to change its filtering effect.
-.TP 2
-Control-u
-remove all characters from the input field.
-.SS Exit codes
-.B gridmenu
-returns
-.B 0
-if Enter is pressed on termination,
-.B 1
-if Escape is pressed.
-.SH SEE ALSO
-.BR gridwm (1)

*
* 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. For each client dwm
* 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 config.h.
*
* To understand everything else, start reading main().
