dwm is a dynamic window manager for X. It manages windows in tiling
and floating modes. Either mode can be applied dynamically, optimizing
the environment for the application in use and the task performed. It
is the little brother of wmii.
dwm contains a small status bar which displays all available tags, the
mode, the title of the focused window, and the text read from standard
input. The selected tags are highlighted with a different color, the
tags of the focused window are highlighted with a small point.

2.18.1
======
This release fixes a bug breaking some QT apps (thanks to Bradley
Hughes for a good test case and lots of patience) a hang with gtk
trunk (not that we expect many to use stable tarball releases of
metacity and bleeding edge versions of gtk together), and a couple
other odds and ends.
- prevent nasty metacity/gdk interactions causing hangs with gtk
trunk (Elijah) [offshoots of #354213]
- avoid some crashes when dragging windows partially offscreen
(Elijah) [#353513]
- avoid mousenav vs. keynav focus problems with the run application
dialog in mouse/sloppy focus modes (Elijah) [#374752]
- send synthetic configure notify events in response to appropriate
MapRequest events too (Elijah) [#322840]

notes:
-yes, there is beryl... it is too complex for the pre-freeze rush
-Mesa-6.5.2 is needed (not at build time, but to run). See pkgsrc-wip.
-the "Composite" extension needs to be anabled in the X server
-at least for intel, Option "XAANoOffscreenPixmaps" is needed, otherwise
some UIs look crippled
go away -- I have real doubts that a version 1.1 jdk and the accompanying
swing are any use to anyone, but am not sure the newer stuff we have
supports all ports which are supported by lang/jdk.
Patch provided by maintainer, Rhialto in PR 35637.
Changes from version 3.7 to 3.8
-------------------------------
1 - Global cleanup
There were some variables shadowing others, things not being
safely initialized, that sort of thing.
[Richard Levitte]
2 - Fixed several memory leaks found by
"Nadav Har'El" <nyh@math.technion.ac.il>.
[Olaf "Rhialto" Seibert]
3 - Merged in the f.movetitlebar command. By default this is bound to
alt-left-click in the titlebar.
[Olaf "Rhialto" Seibert]
4 - Fixed the following issues:
Poking at the code, it looks like InitVirtualScreens() is called
before the configuration file is parsed which would explain what
I see since there's no attempt to create them after the config
file read.
Moving the call after the config parsing causes things to work.
I've run into a few other issues that I fixed with the attached
patch:
- shadow menus on the right screen open the shadow on
the left screen
- shadow menus on the left screen open on top of the
window
- windows on the right screen disappear after startup
[Todd Kover]
5 - Adjustments to ctwm.man:
I noticed a couple of small errors.
One is that the window list arguments for the opaque
keywords are now optional, are listed with square brackets
in the man page. The other is that the two Threshold
keywords are shown in the man page as requiring curly-
brackets, but they are not required or accepted in
configuration files.
[Ross Combs]
6 - improve algoritm to deal with mismatched geometry of virtual
screens
- allow windows to be dragged from one virtual screen to another and
have them switch workspaces appropriately
- handle restarts properly with virtual screens, including preserving
where windows were placed within workspaces regardless of which
virtual screen a window was on; preserve across restarts
[Todd Kover]
7 - WMapCreateCurrentBackGround() and WMapCreateDefaultBackGround()
would skip remaining virtual screens if not all parameters are present.
- small type errors. [Olaf "Rhialto" Seibert].
8 - There were some directives in the config file that wanted to set some
setting for all virtual screens. However since that list is (now) only
set up after parsing the config file, they failed to work. Moreover,
these settings were basically meant to be global to all virtual
screens, so a better place for them is somewhere in *Scr. They all
related to the Workspace Manager, so I moved them from struct
WorkSpaceWindow to struct WorkSpaceMgr.
The affected directives are StartInMapState, WMgrVertButtonIndent,
WMgrHorizButtonIndent, MapWindowCurrentWorkSpace,
MapWindowDefaultWorkSpace. The window and icon_name, even though not
user-settable, were also moved.
This is basically change #7 above done right.
[Olaf "Rhialto" Seibert]
9 - Re-introduced TwmWindow.oldvs, used to avoid calling
XReparentWindow() when possibe (it messed up the stacking order
of windows). However, maybe the use of .vs should be rethought a
bit: in Vanish() it is now set to NULL with the old value kept
in .oldvs. However the window is still a child of the same vs.
Maybe it is better not to set it to NULL and then, when *really*
changing the virtual screen, .vs can be used instead of .oldvs.
This whole "virtual screen" thing is unexplained in the manual,
which even uses it as a synonym for "workspace" already in the
introduction paragraph. (There also does not seem to be a way
now to test virtual screens in captive windows) I suspect that
all this causes lots of confusion, and when cleared up, can
simplify the code a lot.
I also fixed up the horrible indentation in the functions
where I changed something.
[Olaf "Rhialto" Seibert]
10 - Fixed interaction between "inner" and "outer" workspace
selection with "captive" windows. This was because the Gnome
"_WIN_WORKSPACE" property is used in 2 conflicting ways: for
client windows it indicates which workspace they are in, for
root windows it indicates which workspace they show. Captive
windows are both. Also, the initially selected inner workspace
is now the first, not the same as the outer workspace (this had
a different cause).
[Olaf "Rhialto" Seibert]
11 - Introduce Scr->XineramaRoot to store the root window that
encompasses all virtual screen rootwindows. This further reduces
any need to use RealRoot and/or CaptiveRoot.
Add a schematic drawing that clarifies the relation between the
various root-type windows.
[Olaf "Rhialto" Seibert]
12 - Get rid of all non-locale code and make I18N the silent default
(doesn't have to be mentioned any more).
THIS WILL BREAK CTWM ON OLDER (PRE-LOCALE) ENVIRONMENTS.
I strongly recommend an upgrade to "post-locale" standards.
[Richard Levitte]
13 - Enhance RandomPlacement with a displacement argument, so the
pseudo-radomness can be of displacements other than +30+30.
Here's an example for a pretty funky displacement:
RandomPlacement "on" "-30-100"
[Richard Levitte]
14 - Extend the Info window with the geometry seen from the lower
right corner as well.
[Richard Levitte]
15 - Extend the pointer button specification for title buttons
to take modifiers.
As part of this change, the following title pointer button
specification is deprecated:
Button {j} : {function}
in favor of the following, for consistency:
Button {j} = {function}
The old way still works, but is considered bad form and will
be removed in ctwm 4.0.
[Richard Levitte]
16 - Fix position of buttons in Occupy window, to make them centered.
(and spread the remaining space evenly in 4).
[Olaf "Rhialto" Seibert]
17 - "TwmWindow.group" was once apparently set to 0 when a window had
no group leader but this was changed to pointing to its own
window. This resulted however in many places checking for both
conditions, and several checking only for 0 which could not
occur anymore. Changed it back to 0 (so we can now distinguish
again windows that really indicate themselves as group leader,
if we wish) and this gave rise to some simplifications.
Also, there were various loops through all TwmWindows looking
for a group leader (or a transientfor), I replaced them with
GetTwmWindow() which uses the Xlib function XFindContext() which
uses a hash table lookup. This should be more efficient.
When you change the occupation of a group member window, it is
now applied to the group leader (which in turn affects all
members).
I tried this with ExMH, the only program that uses a real group
leader that I could find. Iconifying the leader unmaps the
members. What should "squeezing" do? ExMH also has an icon
window (see ICCCM 4.1.9, 3rd option) which behaves weirdly; this
may be a bug in ExMH (see exmh-2.7.2/exmh.BUGS) even though fvwm
somehow handles it better.
[Olaf "Rhialto" Seibert]
18 - When Squeezing a window group leader, unmap the member windows,
just like happens with iconification.
[Olaf "Rhialto" Seibert]
19 - Simplifications c.q. de-duplications of code regarding the
WorkSpaceManager and Occupation windows. This includes coding
the layout of these windows only once instead of twice (at
initialisation and when resizing). If it's wrong now at least it
should be consistent.
When changing occupation via functions like
f.movetonextworkspace, also move complete window groups (just
like when you do it via the Occupation window).
Also fixed changing the occupation of the Occupation window.
Documented (so far) undocumented possibility to edit the labels
of workspaces on the fly (what use this is, I'm not sure).
Removed some unused variables.
[Olaf "Rhialto" Seibert]
20 - Get rid of the USE_SESSION and X11R6 macros and make them the
silent default. Also cleaned out a few references to the macro
X11R4, which hasn't been used for ages.
THIS WILL BREAK CTWM ON OLDER (PRE-X11R6) ENVIRONMENTS.
I strongly recommend an upgrade to a newer X11 release.
[Richard Levitte]
21 - Modified the random placement so a negative X displacement has
the first "random" window start near the right edge instead of
the right and a negative Y displacement has the first "random"
window start near the bottom edge instead of the top.
[Richard Levitte]
A new bug fix release of Xfce 4.2 is available. This release is supposed to
be the last release for the 4.2 branch. It includes several fixes ported from
the current developpment branch. This release should not be confused with the
upcoming Xfce 4.4 release [1], it's a bug fix release of the previous stable
branch.
[1] Xfce 4.4.0 is already in pkgsrc-wip.
