dwm - dynamic window manager
dwm is a dynamic window manager for X. It manages windows in tiled, monocle
and floating layouts. Either layout can be applied dynamically, optimising the
environment for the application in use and the task performed.
In tiled layouts windows are managed in a master and stacking area. The master
area contains the window which currently needs most attention, whereas the
stacking area contains all other windows. In monocle layout all windows are
maximised to the screen size. In floating layout windows can be resized and
moved freely. Dialog windows are always managed floating, regardless of the
Windows are grouped by tags. Each window can be tagged with one or multiple
tags. Selecting certain tags displays all windows with these tags.
Each screen contains a small status bar which displays all available tags, the
layout, the title of the focused window, and the text read from the root window
name property, if the screen is focused. A floating window is indicated with an
empty square and a maximised floating window is indicated with a filled square
before the windows title. The selected tags are indicated with a different
color. The tags of the focused window are indicated with a filled square in the
top left corner. The tags which are applied to one or more windows are
indicated with an empty square in the top left corner.
dwm draws a small border around windows to indicate the focus state.
prints version information to standard output, then exits.
- X root window name
is read and displayed in the status text area. It can be set with the
click on a tag label to display all windows with that tag, click on the layout
label toggles between tiled and floating layout.
click on a tag label adds/removes all windows with that tag to/from the view.
click on a tag label applies that tag to the focused window.
click on a tag label adds/removes that tag to/from the focused window.

dwm is customized by creating a custom config.h and (re)compiling the source
code. This keeps it fast, secure and simple.
Java applications which use the XToolkit/XAWT backend may draw grey windows
only. The XToolkit/XAWT backend breaks ICCCM-compliance in recent JDK 1.5 and early
JDK 1.6 versions, because it assumes a reparenting window manager. Possible workarounds
are using JDK 1.4 (which doesn't contain the XToolkit/XAWT backend) or setting the
(to use the older Motif backend instead) or running
xprop -root -f _NET_WM_NAME 32a -set _NET_WM_NAME LG3D
(to pretend that a non-reparenting window manager is running that the
XToolkit/XAWT backend can recognize) or when using OpenJDK setting the environment variable
GTK 2.10.9+ versions contain a broken
file dialog implementation,
which requests to reconfigure its window size in an endless loop. However, its
window is still respondable during this state, so you can simply ignore the flicker
until a new GTK version appears, which will fix this bug, approximately
GTK 2.10.12+ versions.
