Read Me

treewm is a window manager that tries to implement a new concept. In addition to
the client windows the user can create desktops which can themselves contain
windows and desktops. By arranging the windows in such a tree the user is able
to manage his tasks efficiently.

treewm is derived by aewm

Some bugs/problems are discussed in PROBLEMS

Start the window manager:
  $ X & or $ X :1 &
  # Press CTRL+ALT+F1 or something like that
  $ DISPLAY=:0 or $ DISPLAY=:1
  $ xterm &
  $ treewm

If you want to start the X window system vi xdm or startx, create an
appropriate ~/.xsession file including as last entry 
  treewm

A more advanced version of ~/.xsession could look like
  #!/bin/bash
  xset m 5
  xterm &
  xsetbg MyFavoriteWallPaper.jpg
  treewm
  while 
    xmessage 'Restart Window Manager?' -buttons Yes:0,No:1 -nearmouse;
    # Just in case treewm crashes or if you want to experiment with the
    # configfile
  do
    treewm;
  done

Introduction (Read this carefully, you won't be able to understand all of
              treewm's features otherwise):

  I'm afraid not everything in this README describes the actual behaviour of
  treewm. If you have any question about how certain things work, feel free
  to write me a mail. Also have a look at the FAQ.

  When you start treewm, you've only got one desktop and all client windows
  are children of this root desktop. Then you can create children of this
  desktop which can have other desktops as children themselves. You can move
  windows and desktops arbitrarily around between desktop. Each window has a
  titlebar. This titlebar is a taskbar as well, desktops have taskbar entries
  for all their children.
  Using the mouse, you can perform the following actions:

  note that raise also means that the icons (if it's a desktop) are raised or
  lowered

  Titlebar - clicks:
    left button:   move (and view window-content)
      + Shift:     make window 'always on top'
    double click with two different buttons: shade
    middle button
      + Shift:     remove 'always on top' / 'always below'
    right button
      + Shift:     make window 'always below' (can be combined with 'always on
                   top' to allow to raise to the top and to lower to the
		   bottom)

  Clicks on taskbar entries:
    left button:   raise
    middle button: restack window directly below the window you click on next
                   with the middle button
      move mouse:  move window onto another desktop
    right button:  lower
      move mouse:  client menu

  Double clicks on taskbar entries:
    left button:   create new desktop
      + Mod1(Alt): collect all windows under the new desktop
    middle button: select desktop on which new windows are created if the
                   window has the focus
    right button:  lower window to bottom

  Clicks on first button:
    left button :  maximize (titlebar not visible)
      + Mod1(Alt): maximize vertically (titlebar not visible)
    middle button: maximize (titlebar visible)
      + Mod1(Alt): maximize vertically (titlebar visible)
    right button:  resize
      + Mod1(Alt): maximize horizontally

  Clicks on second button:
    left button:   close window (double click kills)
      + Mod1(Alt): release all windows to parent if this is a desktop
    middle button: iconify
    right button:  move

  Clicks on desktop background (or on normal window while Alt is pressed, if
                       you press Ctrl actions are performed on the parent):
    left button:   raise
      move mouse:  move / resize (depends on where you click)
    middle button: see above
      move mouse:  change position of virtual desktop
    right button:  lower
      move mouse:  menu

  Clicks on icons
    left button:   perform action
      move mouse:  move icon
    middle button: reparent icon
      + Ctrl:      copy icon
    right button:  raise/lower icons

  Moving mouse out of a Desktop with Alt pressed and VirtualX/VirutalY set
    or moving mouse out of a Desktop with Autoscroll on:
    move virtual desktop by screenwidth/screenheight
  Moving mouse with Button1 pressed:
    change virtual position

  With Shift (+ Alt) pressed, there are three menus available:
    left button:   application menu (see default.cfg), this one is also
                   available on the root desktop without Alt or Shift
    middle btton:  all windows menu
    right button:  all windows under pointer menu


  Since release 0.4.0, there is a vi-like command mode.
  You can access it by pressing Alt+Space, and exit it by Alt+Space again, by
  Esc or by pressing Return when the line is empty. There are two kinds of
  commands: one-key-commands that are executed immediately after the keys are
  pressed and one-line-commands which are executed after the line is finished
  by Return. Upon startup, treewm creates a fifo file called .cmdtreewm. When
  you write commands to this file, they are executed as well as if there were
  typed in the command mode. A list of accepted commands (not in a particular
  order):


  Commands for both icons and windows:
    /regex:     Search for a window whose title matches the regular expression
    n,N:        Find next/previous match
    "xcmd       Execute command 'cmd' on window in register x
    "'cmd       Execute commmand 'cmd' on root window
    !cmd        Execute shell command cmd
    @action     Execute action 'action'
    $menu       Show menu 'menu'
    :           Execute text command (see below)
    t,T         Show current window (like Alt+Tab)

    taskbarbuttons:  desktop has buttons on the taskbar
    buttons:         combination of options titlebarbuttons and taskbarbuttons
    grabkeyboard:    grab the keyboard and send the events to all children.
                     this way you can input something on more than one window
                     simultaneously
                     Note that xterm by default doesn't accept this kind of
                     input. You either have to enable Allow SendEvents in the
                     Ctrl+Button1 Menu or in the ~/.Xdefaults file:
                       xterm*allowSendEvents:<TAB>true
                     Note that this is considered to be a security hole by
                     the xterm programmers, but i don't think so because if
                     someone has access to your X server he's already won.



  With the keyboard, you move around using Mod1 + Up/Down/Left/Right (Mod1 is
  the Alt key on x86 PCs). If you press the shift key, too, you also raise the
  windows you are giving the focus to. If you press the control key, you can
  move the windows between desktops. Additionally, the following keys are
  defined:
    Mod1 +           Esc    : (un)maximize window on whole screen
                              (experimental)
    Mod1 +         + Tab    : next window on lowest desktop level
    Mod1 + Shift   + Tab    : previous window on lowest desktop level
    Mod1 +           Space  : raise window (Control raises parents, too)
    Mod1 + Shift   + Space  : lower window
    Mod1 +         + PgUp   : put window on a higher stacking level
    Mod1 +         + PgDown : put window on a lower stacking level
    Mod1 +           F1     : execute action key1
    Mod1 + Shift   + F1     : execute action key2
    Mod1 +           F3     : shade
    Mod1 + Shift   + F3     : minimize
    Mod1 +           F4     : close window (no desktops)
    Mod1 + Shift   + F4     : kill (destroy) window, close desktop
    Mod1 +           F5     : move window (stop moving with space/return/esc)
    Mod1 + Shift   + F5     : resize window
    Mod1 +           F6     : maximize (titlebar not visible)
    Mod1 + Shift   + F6     : maximize (titlebar visible)
    Mod1 +           F7     : show/hide icons
    Mod1 + Shift   + F7     : create desktop
    Mod1 +         + F8-F12 : go to quick access window
    Mod1 + Shift   + F8-F12 : set quick access window


  You can define the treewm's behaviour in the file ~/.treewm. If you want to
  choose a different config file, just run treewm with the option -f <file>.
  Case is ignored, the following sections are interpreted:
  [Sceme <name>]
  [Client <name>]
  [Action <name>]
  [Menu <name>]
  In these sections you can provide options by lines like
    tag = value
  Sections can be ended and later continued. If there are more than one values
  for one tag, i.e.
    tag = value1
    tag = value2
  the last value in the config file is used.
  You can include the information of other sections by writing
  include = ... Note that you can include more than one section by this line
  and that only those pieces of information are included that were given in
  the config file before that line.

  A Sceme defines the appearance, you can set colors, fonts, pixmaps...  You
  can have multiple scemes, each window belongs to one of these scemes then. A
  client section contains information about a specific client, for instance the
  window position. An action usually is an icon on a desktop which can be used
  to start an application or a desktop (with properties defined in one of the
  client sections). Actions with names key1, key2, key3 are used as keyboard
  shortcuts. The menu section defines a menu you can access with Shift (+ Alt)
  + middle button. If you don't give a section name in a sceme section, this is
  used as a default for all windows. The only menu section currently used is
  the one without section name.
  The complete syntax and the defaults of .treewm can be found in the file
  default.cfg. It is strongly recommended that you create a .treewm file. Look
  at the files default.cfg or sample.cfg for details.

  There is a problem with actions: if treewm starts a program it can't always
  tell whether the windows that appear belong to this client. By default,
  treewm gives the next window that is being mapped the client info specified
  in the action. Some (but not all, unfortunately) apps set the WM_COMMAND
  property on their windows. If you write WM_COMMAND = true in an action
  section, the next window whose WM_COMMAND property is the string the app was
  started with gets the client info supplied by this section. To find out which
  apps set WM_COMMAND use xprop (if there is no WM_COMMAND but a
  WM_CLIENT_LEADER property, type 
    xprop -id <window id of client leader window>). 
  Note that xprop is buggy and does not work correctly with treewm.
  You can provide a regular expression the title is checked for by writing
  Regex = <regex> or you can define a Class Hint the application must set
  (almost every application provides a Class Hint, use xprop to find out about
  that, for details, see default.cfg).



  treewm is _not_ icccm-compliant and will never be.


  There are lots of window mangers out there, so why write another one?

  Well, I think I had some good ideas that are not implemented in any of the
  big window managers. I was impressed by pwm, the only wm I saw which was
  able to use the screen's space reasonably. But I thought window managemant
  could become even more efficient if the windows are arranged in a tree
  rather than in a list, with the windows being leaf nodes. Many wms use
  multiple desktops, so you might think of treewm's concept as a kind of
  generalization of their concepts. In my opinion, a tree is the natural way
  of arranging tasks. For example if want to write and debug a program, you
  can create one desktop with the editor windows, then, on the same level of
  the hierachy you can run and test your program and if you want to have a
  look at the source you just change the desktop and the windows are arranged
  exactly in the same way they were before. If you feel like doing something
  completely different you just have to create another second-level desktop in
  which you can do what you want and later change to your old project again.
  Another important advantage of this concept is its flexibility. There are
  situations in which certain options (for example the focus policy) are quite
  convenient whereas they're quite annoying in another one. So you should be
  able not only to change them globally but also to change them only for a
  special application, that means for a special desktop. A special window
  attribute of some wms, the sticky attribute, occurs in treewm in a quite
  natural way, it simply means that the window is on the parent desktop.

  Looking at many different wms, I found out that no window manager has a
  concept similar to that (though this the most important concept of X) so I
  finally decided to create such a window manager myself.


Sorry for my english!
