+Metacity Standards Compliance
+=============================

+  c. Application Window Properties
+  d. Window Manager Protocols
+3) ICCCM Compliance
+
+1) Introduction
+---------------
+
+This document details metacity compliance with the relevent standards.
+The format of this document is as follows:
+
+[-/+?] Hint Name/Feature Name (Version number)
+       Errata/Comments
+
+The first character indicates the level of compliance as follows:
+    -   none
+    /   partial
+    +   complete
+    ?   unknown
+
+The title indicates a feature or a hint in the specification, and the
+version number indicates the minimum version of the specification
+supported by metacity.  Later versions may be supported if no
+incompatible changes have been made in the specification.
+
+2) EWMH Compliance
+------------------
+
+The EWMH, or Extended Window Manager Hints is a freedesktop.org-
+developed standard to support a number of conventions for
+communication between the window manager and clients.  It builds on
+and extends the ICCCM (See Section 3).  A copy of the current EWMH
+standard is available at http://freedesktop.org/Standards/wm-spec/
+
+  a. Root Window Properties
+  -------------------------
+
++ _NET_SUPPORTED (1.3)
+
++ _NET_CLIENT_LIST (1.3)
+
++ _NET_NUMBER_OF_DESKTOPS (1.3)
+
+- _NET_DESKTOP_GEOMETRY (-)
+  Metacity does not implement large desktops.  Regardless, according
+  to the specification, metacity SHOULD set this property to the
+  screen size, and update it if the screen size changes because of a
+  RandR change.
+
+- _NET_DESKTOP_VIEWPORT (-)
+  Metacity does not implement viewports.  However, according to the
+  specification, metacity MUST set this property to (0,0)
+
++ _NET_CURRENT_DESKTOP (1.3)
+
++ _NET_DESKTOP_NAMES (1.3)
+
++ _NET_ACTIVE_WINDOW (1.3)
+
++ _NET_WORKAREA (1.3)
+
++ _NET_SUPPORTING_WM_CHECK (1.3)
+
++ _NET_VIRTUAL_ROOTS (1.3)
+  Metacity does not read or set this property, but it does not use
+  virtual roots to implement virtual desktops, so it complies with the
+  specification.
+
++ _NET_DESKTOP_LAYOUT (1.3)
+
++ _NET_SHOWING_DESKTOP (1.3)
+
+  b. Root Window Messages
+  -----------------------
+
++ _NET_CLOSE_WINDOW (1.3)
+
+- _NET_MOVERESIZE_WINDOW (-)
+  Metacity does not support this message.  The specification states
+  that metacity should treat this message like a ConfigureRequest.
+  Not hard to implement; just hasn't been done.
+
++ _NET_WM_MOVERESIZE (1.3)
+
+- _NET_RESTACK_WINDOW (-)
+  Metacity does not currently support this message.
+
++ _NET_REQUEST_FRAME_EXTENTS (1.3)  
+
+  c. Application Window Properties
+  --------------------------------
+
++ _NET_WM_NAME (1.3)
+
++ _NET_WM_VISIBLE_NAME (1.3)
+  Metacity does not set this property, but metacity will never display
+  a name different from _NET_WM_NAME
+
++ _NET_WM_ICON_NAME (1.3)
+
++ _NET_WM_VISIBLE_ICON_NAME (1.3)
+  Metacity does not set this property, but metacity will never display
+  a name different from _NET_WM_NAME
+
++ _NET_WM_DESKTOP (1.3)
+
++ _NET_WM_WINDOW_TYPE (1.3)
+
+/ _NET_WM_STATE (1.3)
+  Metacity does not recognize separate vertical and horizontal
+  maximization states.  Currently metacity will do a two-dimensional
+  maximization if either property is set.
+  See: http://bugzilla.gnome.org/show_bug.cgi?id=113601
+  Metacity doesn't implement viewports so _NET_WM_STATE_STICKY is
+  unimplemented.
+  _NET_WM_STATE_DEMANDS_ATTENTION is neither read nor updated by
+  metacity.  Metacity should unset it on window activation.
+
++ _NET_WM_ALLOWED_ACTIONS (1.3)
+  Metacity keeps this hint up to date.  The code is somewhat crufty
+  and should be rewritten, though it is functional.
+  See: http://bugzilla.gnome.org/show_bug.cgi?id=90420
+
++ _NET_WM_STRUT (1.3)
+
++ _NET_WM_STRUT_PARTIAL (1.3)
+
++ _NET_WM_ICON_GEOMETRY (1.3)
+  Metacity uses this property to draw minimize/restore animations
+
++ _NET_WM_ICON (1.3)
+
++ _NET_WM_PID (1.3)
+
++ _NET_WM_HANDLED_ICONS (1.3)
+  Metacity does not read or set this property.  However, metacity
+  never managed iconified windows, and so has no need to do so.
+
+- _NET_WM_USER_TIME (-)
+  Metacity does not read or set this property.  The EWMH does not
+  require it to do so, but it should support it.
+
++ _NET_FRAME_EXTENTS (1.3)
+  If set in response to a _NET_REQUEST_FRAME_EXTENTS message received
+  prior to the window being mapped, this may be an estimate.  This is,
+  however, expressly allowed by the specification.
+
+  d. Window Manager Protocols

+
+ - update the file NEWS based on the ChangeLog

-You need GTK+ 1.3.x (to become 2.0). At the moment CVS HEAD is
-required. Once 1.3.7 is available that will probably work. Metacity is
-a fairly trivial 6000-line C program, so once you get GTK+ built it
-should be no problem to build Metacity.
+You need GTK+ 2.2.  For startup notification to work you need
+libstartup-notification at
+http://www.freedesktop.org/software/startup-notification/ or on the
+GNOME ftp site. You also need GConf 1.2 (unless building a funky
+extra-small embedded metacity with --disable-gconf, see below).

+SHRINKING METACITY
+===
+
+Not that metacity is huge, but a substantial amount of code is in
+preferences handling, in static strings that aren't essential, and in
+the theme engine.
+
+You can strip about 70K from the metacity binary by compiling with 
+options such as:
+
+ --disable-gconf
+ --disable-sm
+ --disable-verbose 
+ --disable-startup-notification
+
+However the result is no good for desktop use, all prefs have to be
+hardcoded in the binary, for example. If you wanted to make a really
+small metacity, here's some additional stuff you might consider
+implementing:
+ 
+ - add --disable-themes, which would replace theme.c and theme-parser.c 
+   with a hardcoded implementation of the interface in theme.h, 
+   should save about 80K. This should be fairly easy.
+
+ - add --disable-gtk, which would implement the interface in ui.h
+   without using GTK. This one is easier than you think because the
+   main part of the window manager doesn't use GTK directly, but is
+   still fairly hard to do.  You would probably have to give up some
+   of the features, such as window menus, as menus are pretty complex
+   to implement well.  So time may be better spent adding a GTK
+   configure script feature to build GTK with only a small core set of
+   functionality.

  - Uses GTK+ 2.0 for drawing window frames. This means colors, fonts, 
    etc. come from GTK+ theme.
 
- - There are 6 workspaces.
+ - Does not expose the concept of "window manager" to the user.  Some
+   of the features in the GNOME control panel and other parts of the
+   desktop happen to be implemented in metacity, such as changing your
+   window border theme, or changing your window navigation shortcuts,
+   but the user doesn't need to know this.

-    Alt-F1 to Alt-F6  switch workspaces
-    Alt-1  to Alt-6   switch workspaces
-    Alt-Tab           forward cycle window focus
-    Alt-Shift-Tab     backward cycle focus
-    Alt-Escape        focus previous window

+   environment. The pager, configuration, etc. are all separate and
+   modular. The "libwnck" library (which I also wrote) is available
+   for writing metacity extensions, pagers, and so on. (But libwnck
+   isn't metacity specific, or GNOME-dependent; it requires only GTK,

-       {

-       }
-
-       class "MetaFrames" style "metacity-style"
-
-   You get the idea. It is just your basic GTK+ rc file, the 
-   window borders are a widget called MetaFrames, 
-   look in frames.c:meta_frames_class_init() for all the style
-   properties that you can configure.
-
-   Metacity-specific styles can also be included in any GTK+ 
-   theme.
-
- - Metacity implements much of the new window manager spec from
-   freedesktop.org, and much of the ICCCM. But then there are 
-   parts of each that it doesn't implement, just because I haven't
-   yet.
+ - Metacity implements much of the EWMH window manager specification

+   the COMPLIANCE file for information on metacity compliance with
+   these standards.
 
  - Uses Pango to render text, so has cool i18n capabilities. 
    Supports UTF-8 window titles and such.
 
+ - There are simple animations for actions such as minimization, 
+   to help users see what is happening. Should probably 
+   have a few more of these and make them nicer.
+
+ - if you have the proper X setup, set the GDK_USE_XFT=1 
+   environment variable to get antialiased window titles.
+

+   them.
+
+ - handles the window manager selection from the ICCCM. Will exit if

+   the --replace argument. So if you're running another
+   ICCCM-compliant WM, you can run "metacity --replace" to replace it

+
+HOW TO ADD EXTERNAL FEATURES
+===
+
+You can write a metacity "plugin" such as a pager, window list, icon
+box, task menu, or even things like "window matching" using the
+Extended Window Manager Hints. See http://www.freedesktop.org for the
+EWMH specification. An easy-to-use library called "libwnck" is
+available that uses the EWMH and is specifically designed for writing
+WM accessories.
+
+You might be interested in existing accessories such as "Devil's Pie"
+by Ross Burton, which add features to Metacity (or other
+EWMH-compliant WMs).
+
 METACITY BUGS, NON-FEATURES, AND CAVEATS
 ===
 
- - Metacity creates a big file in your home directory called
-   ~/metacity.log with a bunch of debug spew.
-
- - If you want a number of workspaces which is not 6, you have to 
-   edit screen.c and recompile.
-
- - If you want keybindings which are not the ones mentioned above
-   as features, you have to edit keybindings.c and recompile.
-
- - Metacity does not have any way to unminimize a window. So 
-   clicking the minimize button is sort of a bad idea.
-   (If you had a WM-spec-compliant tasklist, it would work
-   for unminimization.)
-
- - Metacity uses the new window manager spec, but only random bits of
-   the old GNOME spec. It correctly advertises exactly which parts of
-   the GNOME spec it supports, but it does not support enough of it to
-   make the GNOME task list and desk guide happy, and they do not
-   support the new spec. I don't want anyone to spend time sending me
-   patches to support the old GNOME spec in Metacity; instead, send
-   patches to the task list and desk guide to support the new spec. As
-   far as I know, Metacity does support enough of the new spec to
-   allow a working tasklist and pager.
-
-   Upshot: task list and desk guide DO NOT WORK with Metacity.
-
- - Metacity turns off its keybindings for Emacs, because I use 
-   Alt-space in Emacs, and getting a window menu annoys me.
-   This is a broken feature. My planned fix is to use super/hyper 
-   instead of Alt as the main keybinding shortcut, if super/hyper 
-   exist, and then keyboards with a windows key can use that for 
-   WM functions and Alt for application shortcuts.
-   We'd fall back to Alt if no other suitable modifier existed.
-   
- - Cycling windows with Alt-Tab is flickery, AFAIK because
-   Metacity passes the entire window stack to XRestackWindows() 
-   every time you restack. Instead it should probably only restack 
-   windows that have changed their stacking with respect to one 
-   another. (But sometimes I don't see the flicker, so 
-   I'm not sure.)
-
- - Various operations, such as minimize, maximize, etc., should 
-   have simple animations to make them clearer to users.
-
- - I haven't even read the ICCCM section about colormaps. So if you 
-   have an 8-bit display you are basically screwed.
-
- - Metacity doesn't properly claim the window manager selection
-   as described in the ICCCM. But then, most other window managers
-   don't handle this correctly either.
-
- - There are probably other ICCCM-compliance issues.
-
- - I know there's at least one race condition involving rapidly
-   created and destroyed windows that will crash Metacity.  I think a
-   small test app that did a lot of rapid show/hide on a GtkWindow,
-   in combination with the METACITY_SYNC environment variable and
-   Metacity in a debugger, would turn this up quickly.
-
- - Window placement is always cascade for now; I want to implement 
-   "first fit, falling back to cascade if no fit." 
-   (Configurable placement algorithms are stupid though, don't 
-   send me patches for any bogus ones. Let's just pick a good one.)
-
- - Maximization and movement constraints do not take the 
-   GNOME panel into account. Most of the code already handles
-   this (using workspace->workarea in workspace.h), but 
-   workspace->workarea isn't ever actually calculated.
-   Metacity needs to keep this area up-to-date using the hints the
-   panel sets.
-
- - Should support click-to-focus as an option.
-
- - Windows has a neat way of implementing Alt-Tab for 
-   window cycling that I would like to copy. (The little 
-   popup window thing.)
-
- - People seem to like shortcuts using arrow keys for moving
-   between workspaces. My only question here is that I'm not sure 
-   what the spatial relationship between workspaces is. 
-   (Are they in a grid, or a horizontal row, or what.)
-   I think we may need a window manager spec extension to 
-   share this information between the WM and the pager.
-   We could add left/right arrow and pretend they're in
-   a row for the short term though.
-
- - Should Metacity support flipping in right-to-left locales?
-   I don't know what window managers look like in a right-to-left
-   locale. I assume the window titles should be right-justified;
-   should the window controls also be flipped?
-
- - Need keyboard shortcuts for hide/show desktop (minimize/unminimize
-   all windows temporarily, basically, and focus desktop); also 
-   for focusing dock windows (though since current GNOME panel has 
-   no useful keynav, this doesn't get you far at the moment).
-
- - Resize menu item doesn't do anything. It's intended to enter
-   resize-with-the-keyboard mode, similar to Move menu item.
-
- - I haven't set up the po subdir and translations, mostly because
-   autotools seem to get all confused if you set these up but 
-   don't actually have any translations. So if someone translates
-   something we can set it up.
-
- - If you switch from sawfish to metacity without restarting X, 
-   the panel often ends up buried behind the Nautilus desktop window.
-
-   What happens is that the panel detects Sawfish has gone away, and
-   turns on override redirect mode because no GNOME-aware WM is
-   running (i.e. it goes into "ignore the window manager" mode). But
-   the panel doesn't notice that Metacity has appeared and is
-   (partially) GNOME-compliant. So Metacity doesn't see the override
-   redirect panel, and leaves it behind the Nautilus desktop. I'm not
-   sure whether Metacity or the panel is to blame for this.
-
-   (To debug - use "xwininfo" on the panel, if override redirect is
-    "Yes" then Metacity won't have any awareness of a window and can't
-    properly stack it above the desktop. If override redirect is "No"
-    then Metacity can see the panel and handle it properly. Look at
-    xstuff.c:xstuff_is_compliant_wm() in the panel to get started on
-    how the panel deals with this.)

+   OS vendors.
 
 Q: Is Metacity a Red Hat project?
 
-A: Metacity is in no way funded, endorsed, or encouraged by Red Hat,

+   You may think this means that you won't have certain keybindings, 
+   or something like that. This is a misconception. The only 
+   _fundamental_ difference between viewports and workspaces is that 
+   with viewports, windows can "overlap" and appear partially on

+
+Q: Why is the panel always on top?
+
+A: Because it's a better user interface, and until we made this not

+
+   Please don't just "me too!" on bugzilla bugs, please don't think
+   flames will get you anywhere, and please don't repeat rationale
+   that's already been offered.
+
+Q: Your dumb web pages you made me read talk about solving problems in
+   fundamental ways instead of adding preferences or workarounds.
+   What are some examples where metacity has done this?
+
+A: There are quite a few, though many opportunities remain.  Sometimes
+   the real fix involves application changes. The metacity approach is
+   that it's OK to require apps to change, though there are also
+   plenty of workarounds in metacity for battles considered too hard
+   to fight.
+
+   Here are some examples:
+
+   - fullscreen mode was introduced to allow position constraints,
+     panel-on-top, and other such things to apply to normal windows
+     while still allowing video players etc. to "just work"
+
+   - "whether to include minimized windows in Alt+Tab" was solved 
+     by putting minimized windows at the *end* of the tab order. 
+
+   - Whether to pop up a feedback display during Alt+Tab was solved by
+     having both Alt+Tab and Alt+Esc
+
+   - Whether to have a "kill" feature was solved by automatically
+     detecting and offering to kill stuck apps. Better, metacity
+     actually does "kill -9" on the process, it doesn't just
+     disconnect the process from the X server. You'll appreciate this
+     if you ever did a "kill" on Netscape 4, and watched it keep
+     eating 100% CPU even though the X server had booted it.
+
+   - The workspaces vs. viewports mess was avoided by adding
+     directional navigation and such to workspaces, see discussion
+     earlier in this file.
+
+   - Instead of configurable placement algorithms, there's just one 
+     that works fairly well most of the time.
+
+   - To avoid excess CPU use during opaque move/resize, we rate limit
+     the updates to the application window's size.
+
+   - Instead of configurable "show size of window while resizing,"
+     it's only shown for windows where it matters, such as terminals.
+     (Only use-case given for all windows is for web designers
+     choosing their web browser size, but there are web sites and
+     desktop backgrounds that do this for you.)
+
+   - Using startup notification, applications open on the workspace
+     where you launched them, not the active workspace when their
+     window is opened.
+
+   - and much more.
+
+Q: I think metacity sucks.
+
+A: Feel free to use any WM you like. The reason metacity follows the
+   ICCCM and EWMH specifications is that it makes metacity a modular,
+   interchangeable part in the desktop. libwnck-based apps such as the
+   GNOME window list will work just fine with any EWMH-compliant WM.
+
 Q: Did you spend a lot of time on this?
 
-A: Metacity is about 6000 lines of code, which took a few weekends and
-   evenings to write. If it ever becomes more polished it will
-   probably grow 2-3 more thousand lines of code and suck a few more
-   weekends of time. If I started adding all kinds of features and 
-   crack-ridden configuration options, it might take more time than that. 
+A: Originally the answer was no. Sadly the answer is now yes.
 
 Q: How can you claim that you are anti-crack, while still 
    writing a window manager?
 
 A: I have no comment on that.

+ * egg_accelerator_parse_virtual:
+ * @accelerator:      string representing an accelerator
+ * @accelerator_key:  return location for accelerator keyval
+ * @accelerator_mods: return location for accelerator modifier mask
+ *
+ * Parses a string representing a virtual accelerator. The format
+ * looks like "&lt;Control&gt;a" or "&lt;Shift&gt;&lt;Alt&gt;F1" or
+ * "&lt;Release&gt;z" (the last one is for key release).  The parser
+ * is fairly liberal and allows lower or upper case, and also
+ * abbreviations such as "&lt;Ctl&gt;" and "&lt;Ctrl&gt;".
+ *
+ * If the parse fails, @accelerator_key and @accelerator_mods will
+ * be set to 0 (zero) and %FALSE will be returned. If the string contains
+ * only modifiers, @accelerator_key will be set to 0 but %TRUE will be
+ * returned.
+ *
+ * The virtual vs. concrete accelerator distinction is a relic of
+ * how the X Window System works; there are modifiers Mod2-Mod5 that
+ * can represent various keyboard keys (numlock, meta, hyper, etc.),
+ * the virtual modifier represents the keyboard key, the concrete
+ * modifier the actual Mod2-Mod5 bits in the key press event.
+ * 
+ * Returns: %TRUE on success.
