labwc 0.7.2

This release is the second in a row that is larger than usual in terms of both
fixes and new features. Significant additions include input-methods, pipemenus,
snap-to-edge overlays and optionally drop-shadows.

As usual, most of the commits are by the core devs: @ahesford, @Consolatis,
@jlindgren90, @johanmalm and @tokyo4j, but we also have many great
contributions from others as noted in the log.

Added

• Add <menu><ignoreButtonReleasePeriod> to prevent clicks with small movements
  from inadvertantly closing a menu or selecting a menu item. This is the
  equivalent of <menu><hideDelay> on Openbox. #1760
• Support drop-shadows (disabled by default) for windows using server-side
  decorations. Written-by: @cillian64

<theme>
  <dropShadows>yes|no</dropShadows>
</theme>

window.active.shadow.size: 60
window.inactive.shadow.size: 40
window.active.shadow.color: #00000060
window.inactive.shadow.color: #00000040

• Add window-rule ignoreConfigureRequest to ignore X11 client-side
  configure requests (positioning and resizing). #1446
• Support window-rules based on window type: <windowRule type="">, where
  type can be for example NET_WM_WINDOW_TYPE_DESKTOP for an XWayland
  window. Written-by: @xi @txgk
• Add none branch to the ForEach action. Written-by: @nicolas3121
  #1298

<action name="ForEach">
  <query identifier="foo"/>
  <then>
    <!-- carry out some action on match -->
  </then>
  <none>
    <!-- carry out some action if there were no matches at all -->
  </none>
</action>

• Add -S|--session <command> option to start <command> on startup and
  to terminate the compositor when exits. This is useful for
  session management as it allows the session client (for example
  lxqt-session) to terminate labwc when exiting itself.
• In theme setting color definitions, support inline alpha encoding like
  #aabbccff
• Add window-switcher custom field inspired by printf formatting. #1670
  Written-by: @droc12345 and @Consolatis

<windowSwitcher>
  <fields>
    <field content="custom" format="foobar %b %3s %-10o %-20W %-10i%t" width="100%" />
  </fields>
</windowSwitcher>

• Support defining window-switcher width as a percentage of output
  (display) width. Written-by: @droc12345

osd.window-switcher.width: 75%

• Support Openbox compatible pipe-menus. See labwc-menu(5) for usage.
• Add snap-to-edge overlay. Written-by: @tokyo4j. PR #1652 #1702
  This includes the following new config and theme settings:

<snapping>
  <overlay>
    <enabled>yes|no</enabled>
    <delay inner="500" outer="500"/>
  </overlay>
</snapping>

snapping.overlay.[region|edge].bg.enabled: yes|no

snapping.overlay.[region|edge].bg.color: #8080b380
snapping.overlay.[region|edge].border.width: 1
snapping.overlay.[region|edge].border.color: #ffffff,#000000,#ffffff

• Add theme settings listed below for window-switcher preview border.
  Written-by: @tokyo4j

osd.window-switcher.preview.border.width: 2
osd.window-switcher.preview.border.color: #ffffff,#00a2ff,#ffffff

• Support libinput config option for calibration matrices.
  <libinput><device><calibrationMatrix>. Written-by: @SnowNF
• Add new window-switcher field content types workspace, state,
  type_short and output. Written-by: @droc12345 PR #1623

<windowSwitcher allWorkspaces="yes">
  <fields>
    <field content="workspace" width="5%" />
    <field content="state" width="3%" />
    <field content="type_short" width="3%" />
    <field content="output" width="9%" />
    <field content="identifier" width="30%" />
    <field content="title" width="50%" />
  </fields>
</windowSwitcher>

• Support input methods (or input method editors, commonly abbreviated
  IMEs) like Fcitx5, using protocols text-input-v3 and input-method-v2.
  This includes IME popups. Written-by: @tokyo4j
• Add atCursor attribute to action ShowMenu so that a window's
  "client-menu" could optionally be launched at the pointer using a
  keybind as follows:

<action name="ShowMenu" menu="value" atCursor="yes" />

• Support workspace-prefix (<desktops><prefix>) for workspace-switcher
  onscreen display when naming workspaces by digits, for example 1, 2, 3
  Written-by: @droc12345
• Process all *.env files in an environment.d directory alongside and
  in the same way as each potential environment file.
• Allow empty variables in environment files. In other words, respond to
  variable declarations of the form "VARIABLE=", with no following value,
  by setting the corresponding environment variable as an empty string.
• Add optional headless fallback output that is automatically created when
  no other output exists. Enable this by setting the environment variable
  LABWC_FALLBACK_OUTPUT to the desired output name. The feature
  benefits applications like wayvnc the most by ensuring that there is
  always an output available to connect to. #1618
  Co-Authored-By: Simon Long [email protected]
• Optionally show windows on all workspaces in window-switcher.

<windowSwitcher allWorkspaces="yes">

  Written-by: @spl237
• Updated dbus activation environment with more environment variables
  (XCURSOR_SIZE, XCURSOR_THEME, XDG_SESSION_TYPE, LABWC_PID)
  Written-by: @winerysearch Issue #694
• Run shutdown script on exit (equivalent to autostart on startup)
• Add wrap argument to action MoveToOutput. Wrap is disabled by
  default to keep the user interface consistent. Example usage:

<action name="MoveToOutput" direction="right" wrap="yes" />

• Ensure titlebar has consistent look when using transparency. #1684
• Fix dnd bug where dnd does not finish properly on cursor-button-release
  if there is no surface under the cursor such as on the desktop when no
  background client is running. #1673
• Send cursor-button release event to CSD client before finishing window
  dragging to avoid a bug whereby the release event is incorrectly sent to
  a layer-shell client at the end of a drag.
• Validate double-click against SSD part type because clicks on
  different parts of a client in quick succession should not be
  interpreted as a double click. #1657
• Fix bug that region overlay is not shown when a modifier key is re-
  pressed.
• Fix workspace-switcher on-screen-display positioning of text using
  right-to-left (RTL) locales. Written-by: @micko01 Issue #1633
• Unconstrain xdg-shell popups to usable area (rather than full output) so
  that popups do not cover layer-shell clients such as panels.
  Written-by: @tokyo4j
• Exclude unfocusable XWayland windows (for example notifications and
  floating toolbars) from being processed by wlr-foreign-toplevel protocol
  as these windows should not be shown in taskbars/docks/etc.
• Render text buffers with opaque backgrounds because subpixel text
  rendering over a transparent background does not work properly with
  cairo/pango. PR #1631 issue #1684
• Fallback on layout 'us' if a keymap cannot be created for the provided
  XKB_DEFAULT_LAYOUT. If keymap still cannot be created, exit with a
  helpful message instead of a segv crash.
• Reload cursor theme and size on reconfigure. This gives instant feedback, but
  only works for server side cursors or clients using the cursor-shape protocol.
  Written-by: @spl237 and @Consolatis. #1587 #1619
• Fix a number of surface-focus related short-comings:
  • Handle cursor-button-press on layer-shell subsurfaces and fix bug in
    get_cursor_context() which resulted in layer-surfaces not being
    detected correctly. PR #1594
  • Overhaul the logic for giving keyboard focus to layer-shell clients.
    PR #1599 Issue #1653
• Fix move/resize bug manifesting itself on touchpad taps with
  <tapAndDrag> disabled because libinput sends button press & release
  signals so quickly that interactive_finish() is never called.
  Written-by: @tokyo4j

• Fix view_get_adjacent_output() bug resulting in often returning an
  incorrect output when using more than two outputs. Issue #1582

Changed

• Support press-move-release when interacting with the labwc root-menu. #1750
• In theme settings, mark color definitions in the format #rrggbb aaa as
  deprecated (still supported, but will removed in some future release) in
  favor of the more commonly used `#rr...

0.7.1

</libinput>

• Add data/labwc.svg & data/labwc-symbolic.svg, and specify icon name
  in labwc.desktop to enable Display Managers to show an icons for labwc.
• Expose output configuration test to clients. For example, this enables
  wlr-randr --dryrun
• Add window-edge resistance for interactive moves/resizes and support negative
  strengths to indicate attractive snapping. Written-by: @ahesford

<resistance>
  <screenEdgeStrength>-20</screenEdgeStrength>
  <windowEdgeStrength>-20</windowEdgeStrength>
</resistance>

• Set keyboard layout on reconfigure. Issue #1407
• Reset keyboard-layout group (index) for each window on reconfigure if
  the keymap has changed.
• Support merging multiple config files with the --merge-config command
  line option. Issue #1406

  Optionally, make this only apply to specific named devices.
  Written-by: @jp7677

<touch mapToOutput=""/>
<touch deviceName="" mapToOutput=""/>

• Add tablet support including:
  • Mapping of tablet to output (display)
  • Emulation of cursor movement and button press/release
  • Configuration of area and rotation
    Written-by: @jp7677 @Consolatis

  <area top="0.0" left="0.0" width="0.0" height="0.0" />
  <map button="Tip" to="Left" />
  <map button="Stylus" to="Right" />
  <map button="Stylus2" to="Middle" />
</tablet>

• Add tearing support. #1390. Written-by: @Ph42oN @ahesford
• Add configuration support for mouse buttons Side, Extra, Forward,
  Back and Task. Written-by: @jp7677
• config: allow <libinput><device> without category attribute to define a
  default profile because it is more user-friendly and intuitive.
• Add a configuration option to enable adaptive sync only when an application
  is in fullscreen mode. Written-by: @Ph42oN
• Add touchpad libinput device type to increase configuration flexibility,
  for example allowing naturalScroll on touchpads, but not on regular pointer

  • MoveToOutput, FitToOutput (by @jp7677)
  • Shade, Unshade, ToggleShade (by @ahesford @Consolatis)
• Add config option <placement><policy> with supported values center,
  cursor and automatic. The latter minimizes overlap with other windows
  already on screen and is similar to Openbox's smart window placement.
  The placement policies honour <core><gap>.
  Written-by: @ahesford #1312

<placement>
  <policy>center|automatic|cursor</policy>
</placement>

Fixed

• Delay popup-unconstrain until after first commit in response to a changed
  wlroots 0.17 interface and to get rid of the error message below. Issue #1372

  [types/xdg_shell/wlr_xdg_surface.c:169] A configure is scheduled for an uninitialized xdg_surface

• Notify clients about configuration errors when changing output settings.
  Issue #1528.

• Fix output configuration bug causing compositor crash when refresh rate is
  zero. Issue #1458

• Fix disappearing cursor bug on view destruction. Issue #1393

• Use used specified config-file (using -c command line option) on
  reconfigure.

• Assign outputs to new views on surface creation instead of mapping, and
  notify the client of the preferred output scale when doing so. This fixes an
  issue with foot: https://codeberg.org/dnkl/foot/issues/1579
  Written-by: @ahesford

• Cancel key repeat on vt change to fix crash on VT change on FreeBSD.
  Issue #1424

• Fix crash when a minimized fullscreen window closes. Written-by: @bi4k8

• Execute menu actions after closing menus so that menu entries can issue
  wtype commands to the surface with keyboard-focus. Issue #1366

• Try to honor original window geometry on layout changes.

• Fix virtual keyboard bug experienced with wlrctl keyboard type xyz. Do not
  process virtual keyboard keycodes (just the keysyms). Issue #1367

• Sync xdg-shell client view->pending when applying geometry to fix issue
  caused by applications choosing not respond to pending resize requests either
  by ignoring them or substituting alternative sizes (for example, when mpv
  constrains resizes to keep its aspect ratio fixed). Written-by: @ahesford

Changed

• Make MoveToCursor honour <core><gap>. Issue #1494
• Add Roll Up/Down client-menu entry for ToggleShade
• When a Wayland-native window is snapped to a screen edges or user-defined
  region, labwc will notify the application that it is "tiled", allowing the
  application to better adapt its rendering to constrained layouts. Windows
  with client-side decorations may respond to these notices by squaring off
  corners and, in some cases, disabling resize abilities. This can be disabled
  with:

<snapping>
  <notifyClient>never</notifyClient>
</snapping>

or limited to only edge-snapped or only region-snapped windows. See the
labwc-config(5) manual page for more information.

• When a window is dragged from a snapped position (either a screen edge or a
  user-defined region), the snapped state is now discarded as soon as the
  dragging begins. This means that dragging from a snapped position to a
  maximized state (with the topMaximize option enabled) and then
  un-maxmimizing the window will restore the window to its size and position
  before it was snapped. In previous releases, un-maximizing would restore
  the window to its snapped state. To preserve the snapped state of a window
  when maximized, use the Maximize window button or the ToggleMaximize
  action.

• The new windowEdgeStrength setting makes windows resist interactive moves and
  resizes across the edges of other windows. This can be disabled with:

<resistance>
  <windowEdgeStrength>0</windowEdgeStrength>
</resistance>

• Run menu actions on button release intead of press.
• Constrain window size to that of usable area when an application is started.
  Issue #1399
• Support showing the full app_id in the window switcher. Users with a custom
  windowSwitcher configuration should use the trimmed_identifier field
  label to preserve existing behavior; the identifier field now refers to the
  full app_id. Consult the labwc-config(5) manual page for more details.
  Issue #1309

0.7.0

labwc 0.7.0

The main effort in this release has gone into porting labwc to wlroots 0.17
and tidying up regressions. Nonetheless, it contains a significant number of
additions and fixes as described below.

Should bug fixes be required against 0.6.6 (built with wlroots 0.16), a
0.6 branch will be created.

Added

• Support titlebar hover icons. Written-by: @spl237
• Add theme options osd.workspace-switcher.boxes.{width,height}
  Written-by: @kyak
• Add actions VirtualOutputAdd and VirtualOutputRemove to control virtual
  outputs. Written-by: @kyak (#1287)
• Teach MoveToEdge to move windows to adjacent outputs.
  Written-by: @ahesford
• Implement <font place="InactiveWindow">. Written-by: @ludg1e (#1292)
• Implement cursor-shape-v1 protocol to allow Wayland clients to request a
  buffer for a cursor shape from a compositor. Written-by: @heroin-moose
• Implement fractional-scale-v1 protocol to allow Wayland clients to properly
  scale on outputs with fractional scale factor. Written-by: @heroin-moose
• Add ResizeTo action (#1261)
• Allow going backwards in window-switcher OSD by using arrow-up or arrow-left.
  Written-by: @jp7677
• Add ToggleOmnipresent action and add an "Always on Visible Workspace" entry
  for it in the client-menu under the Workspaces submenu. Written-by: @bnason
• Account for space taken up by XWayland clients with _NET_WM_STRUT_PARTIAL
  property in the usable_area calculation. This increases inter-operability
  with X11 desktop componenets.
• Set XWayland's _NET_WORKAREA property based on usable area. XWayland
  clients use the _NET_WORKAREA root window property to determine how much of
  the screen is not covered by panels/docks. The property is used for example
  by Qt to determine areas of the screen that popup menus should not overlap.

Fixed

• Fix xwayland.c null pointer dereference causing crash with CLions. (#1352)
• Fix issue with XWayland surfaces completely offscreen not generating commit
  events and therefore preventing them from moving onscreen.
• Do not de-active windows when layer-shell client takes keyboard focus, to
  fix sfwbar minimize action. (#1342)
• Move layer-shell popups from the background layer to the top layer to render
  them above normal windows. Previously this was only done for the bottom
  layer. In support of Raspberry Pi's pcmanfm --desktop. (#1293)
• Calculate usable_area before positioning clients to ensure it is correct
  before non exclusive-zone layer-shell clients are positioned or resized.
  (#1285)
• Prevent overriding XWayland maximized/fullscreen/tiled geometry to fix an
  issue where some XWayland views (example: xfce4-terminal) do not end up with
  exactly the correct geometry when tiled.

Changed

• Treat XWayland panel windows as if fixedPosition rule is set
• Use the GTK3 notebook header color as the default active title color
  (small change from #dddad6 to #e1dedb). Written-by: @dimkr

0.6.6

labwc 0.6.6

Added

• Add fixedPosition window-rule property to avoid re-positioning windows
  on reserved-output-space changes (determined by settings or
  exclusive layer-shell clients) and to disallow interactive move or
  resize, for example by alt+press.
• Add Unfocus action to enable unfocusing windows on desktop click.
  Issue: #1230
• Add config option <keyboard layoutScope="window"> to use per-window
  keyboard layout. Issue #1076
• Support separate horizontal and vertical maximize by adding a
  direction option to actions Maximize and ToggleMaximize.
• Add actions GrowToEdge and ShrinkToEdge. Written-by: @digint
• Add snapWindows option to MoveToEdge action. Written-by: @digint
• Add MoveToCursor action. Written-by: @Arnaudv6
• Add config option <keyboard><numlock> to enable Num Lock on startup.
• Support Meta (M), Hyper (H), Mod1, Mod3, Mod4 and Mod5 modifiers in
  keybind definitions. Fixes: #1061
• Add themerc 'titlebar.height' option. Written-by: @mozlima
• Add If and ForEach actions. Written-by: @Consus
• Allow referencing the current workspace in actions, for example:
  <action name="SendToDesktop" to="current"/>

Fixed

• Do not reset XWayland window SSD on unminimize
• Keep XWayland stacking order in sync when switching workspaces
• Update top-layer visiblity on workspace-switch in order to show
  top-layer layer-shell clients correctly when there is a window in
  fullscreen mode on another workspace. Issues: #1040 #1158
• Make interactive window snapping with mouse more intuitive in
  multi-output setups. Written-by: @tokyo4j
• Try to handle missing set_window_geometry with Qt apps which
  occasionally fail to call set_window_geometry after a configure
  request, but correctly update the actual surface extent. Issue: #1194
• Update XWayland stacking order when moving a window to the front/back.
• Prevent switching workspaces for always-on-bottom windows. Fixes: #1170
• Fix invisible cursor after wlopm --off && wlopm --on.
• When a session is locked using 'session-lock' protocol, reconfigure for
  output layout changes to avoid incorrect positioning
• Account for window base size in resize indicator so that the displayed
  size exactly matches the terminal grid, for example 80x25.
• The following focus related issues:
  • Allow re-focusing xwayland-unmanaged surfaces in response to pointer
    action (click or movement if focus-follow-mouse is enabled). This
    enables clients such as dmenu, rofi and jgmenu to regain
    keyboard-focus if it was lost to another client.
  • Fix code paths which could lead to a lock-screen losing focus, making
    the session impossible to unlock or another surface to gain focus thus
    breaching the session lock.
  • Only focus topmost view on unmap if unmapped view was focused.
  • Fix xwayland_surface->data bug relating to unmanaged surfaces.
  • Fix layer subsurface focus bug to make waybar's minimize-raise work.
    Fixes: #1131
  • Ignore focus change to unmanaged surface belonging to same PID to fix
    an issue with menus immediately closing in some X11 apps.
  • Avoid focusing xwayland views that do not want focus using the ICCCM
    "Globally Active" input model.
  • Allow re-focus between "globally active" XWayland views of the same
    PID.
  • Assume that views that want decorations also want focus
• The following keyboard and keybind related issues:
  • Send pressed keys correctly when focusing new surface.
  • Refactor handling of pressed/bound keys to send (to client) the
    release events for any pressed key that was not part of a keybind,
    typically because an unrelated non-modifier key was pressed before
    and held during a keybind invocation. Fixes #1091 #1245
  • Fix keyboard release event bug after session lock. Fixes: #1114
• Raise xdg and xwayland sub-views correctly relative to other sub-views,
  by letting the relative stacking order between them change.
• Honor initially maximized requests for XWayland views via
  _NET_WM_STATE.
• For initially maximized XWayland views, set the stored natural geometry
  to be output-centered.
• Fix regions rounding error sometimes resulting in incorrect gaps
  between regions.

Changed

• Move floating windows in response to changes in reserved output space
  (determined by settings or exclusive layer-shell clients such
  as panels). Users with window-rules for panels and/or desktops should
  add the fixedPosition property to avoid regression. Issue: #1235
• Restore SIGPIPE default handler before exec. Fixes: #1209
• With the introduction of directional Maximize, right-click on the
  maximize button now toggles horizontal maximize, while middle-click
  toggles vertical maximize.
• Make MoveToEdge snap to the next window edge by default rather than
  just the screen edge.
• Comment out variables in docs/environment to avoid users using the
  file without editing it and ending up with unwanted settings.
  Fixes: #1011
• Set _JAVA_AWT_WM_NONREPARENTING=1 unless already set.
• This release has seen significant refactoring and minor improvements
  with respect to window and surface focus (particular thanks to
  @jlindgren90). This work has helped uncover and fix some hard-to-find
  bugs. We don't believe that there are any regressions, but can't say
  for sure.
• Set Num Lock to enabled by default on start up
• Allow switching VT when locked
• Use fnmatch() for pattern matching instead of g_pattern_match_simple()
  because it is a POSIX-compliant function which has a glob(7) manual page
  for reference.
• Title context is used instead of TitleBar for the default client-menu
  on click. This means that if a button is right-clicked, the client-menu
  will not appear anymore.
• Always switch to the workspace containing the view being focused.

0.6.5

Added

• Support png and svg titlebar buttons
• Support on/off boolean configuration values (in addition to true, false,
  yes and no). Written-by: @redtide
• keybinds
  • Allow non-english based keybinds
  • Make keybind agnostic to keyboard layout. Fixes #1069
  • Add optional layoutDependent argument to only trigger if the
    configured key exists in the currently active keyboard layout.
    <keybind key="" layoutDependent="">
  • Fallback on raw keysyms (as if there were no pressed modifier) for
    bindings which do not match against translated keysyms. This allows
    users to define keybinds such as "S-1" rather than "S-exclam". It also
    supports "W-S-Tab". Fixes #163 #365 #992
• window-rules: add ignoreFocusRequest property
• config: support libinput <tapAndDrag> and <dragLock>.
  Written-by: @tokyo4j
• Handle keyboard input for menus. Fixes #1058
• Server-side decoration:
  • Make corners square on maximize
  • Disable border on maximize. Fixes #1044
• Add window resize indicator and associated <resize><popupShow> config
  option
• Add <theme><keepBorder> to give ToggleDecoration three states:
  (1) disable titlebar; (2) disable whole SSD; and (3) enables whole SSD
  When the keepBorder action is disabled, the old two-state behavior is
  restored. Fixes #813
• Minimize whole window hierarchy from top to bottom regardless of which
  window requested the minimize. For example, if an 'About' or 'Open File'
  dialog is minimized, its toplevel is minimized also, and vice versa.
• Move window's stacking order with dialogs so that other window cannot be
  positioned between them. Also position xdg popups above their parent
  windows.This is consistent with Gtk3 and Qt5. Fixes #823

Fixed

• Clarify in labwc-config(5) that keyboard modifiers can be used for
  mousebinds. Fixes #1075
• Ensure interactive move/resize ends correctly for CSD clients. Fixes #1053
• Fix invalid value in <accelProfile> falling back as "flat"
• Fix touch bug to avoid jumping when a touch point moves off of a surface
  Written-by: @bi4k8
• Prevent crash with theme setting osd.window-switcher.width: 0.
  Fixes #1050
• Cancel cursor popup grab on mouse-press outside client itself, for
  example on any part of the server side decoration or the desktop.
  Fixes #949
• Prevent cursor press on layer-subsurface from cancelling popup grab
  Fixes #1030
• xwayland: fix client request-unmap bug relating to foreign-toplevel handle
• xwayland: fix race condition resulting in map view without surface
• Limit SSD corner radius to the height of the titlebar
• Fix rounded-corner bug producing weird artefacts when very large border
  thickness is used. Fixes #988
• Ensure string_prop() handlers deal with destroying views. Fixes #1082
• Fix SSD thickness calculation bug relating to titlebar. Fixes #1083
• common/buf.c:
  • Do not expand $() in buf_expand_shell_variables()
  • Do not use memcpy for overlapping regions

Changed

• Use identifier for window-switcher field rather than app_id to be
  consistent with window rules.

  <windowSwitcher>
    <fields>
      <field content="identifier" width="25%"/>
    </fields>
  </windowSwithcer>
  

• Do not expand environment variables in Exec action <command>
  argument (but still resolve tilde).

0.6.4

0.6.2

0.6.2 - 2023-03-20

This release contains refactoring and simplification relating to
view-output association and xdg/xwayland configure/map events.

Unless otherwise stated all contributions are by the core-devs
(@Consolatis, @jlindgren90 and @johanmalm).

Added

• Add config option <core><windowSwitcher show="no" /> to hide
  windowSwitcher (also known as On Screen Display) when switching windows.

• Enable config option <core><windowSwitcher preview="" /> by default.

• Add ToggleKeybinds action to disable/enable all keybinds (other than
  ToggleKeybinds itself). This can be used to better control Virtual
  Machines, VNC clients, nested compositors or similar. (#738 and #810)

• Implement cursor constraints (Written-by: @Ph42oN) and lock confinement.

• Support xdg-activation protocol to allow applications to activate
  themselves (e.g. raise to the top and get keyboard focus) if they
  provide a valid xdg_activation token.

• Allow clearing key/mouse bindings by using the 'None' action. This
  enables the use of <default /> and then selectively removing keybinds.
  For example the following could be used to allow using A-Left/Right with
  Firefox.

  <keyboard>
    <default/>
    <keybind key="A-Left"><action name="None" /></keybind>
    <keybind key="A-Right"><action name="None" /></keybind>
  </keyboard>
  

Fixed

• Prevent cursor based region-snapping when starting a move with Alt-Left.
  If region-snapping is wanted in this situation, just press the modifier
  again. (#761)
• Prevent rare crash due to layering move/resize/menu operations. (#817)
• Fully reset config default values on Reconfigure if not set in config
  file.
• Fix visual glitch when resizing xfce4-terminal from left edge caused by
  windows not accepting their request size exactly.
• Fix issue with havoc not having a valid size on map.
• Save natural_geometry.x/y with initially maximized xdg-view to fix an
  issue where, if Thunar was started maximized, it would un-maximize to
  the top-left corner rather than the center.

Changed

• Change config option <cycleView*> to <windowSwitcher>.
  Use <core><windowSwitcher show="yes" preview="no" outlines="yes" />
  instead of:

  <core>
    <cycleViewOSD>yes</cycleViewOSD>
    <cycleViewOutlines>yes</cycleViewOutlines>
    <cycleViewPreview>yes</cycleViewPreview>
  </core>

0.6.0

labwc 0.6.0

This release contains significant refactoring to use the wlroots
scene-graph API. This touches many areas of the code, particularly
rendering, server-side-decoration, the layer-shell implementation and the
menu. Many thanks to @Consolatis for doing most of the heavy lifting with
this.

Noteworthy, related changes include:

• The use of a buffer implementation instead of using wlr_texture. It
  handles both images and fonts, and scales according to output scale.
• The use of node-descriptors to assign roles to wlr_scene_nodes in order
  to simplify the code.
• Improving the "Debug" action to print scene-graph trees

A large number of bugs and regressions have been fixed following the
re-factoring, too many to list here, but we are grateful to all who have
reported, tested and fixed issues. Particular mentions go to @bi4k8,
@Flrian, @heroin-moose, @jlindgren90, @Joshua-Ashton, @01micko and @skerit

Added

• Allow xdg-desktop-portal-wlr to work out of the box by initializing dbus
  and systemd activation environment. This enables for example OBS Studio

  assigned to xwayland to NULL whenever Xwayland terminates).
  Issues #166 #444. Written-by: @Consolatis. Helped-by: @droc12345
• Increase File Descriptor (FD) limit to max because a compositor has to
  handle many: client connections, DMA-BUFs, wl_data_device pipes and so on.
  Fixes client freeze/crashes (swaywm/sway#6642). Written-by: @Joshua-Ashton
• Fix crash when creating a cursor constraint and there is no currently
  focused view.
• Gracefully handle dying client during interactive move.
  Written-by: @Consolatis

  elements without over-writing their values. Written-by: @bi4k8
• theme: change window.label.text.justify default to center
• Redefine the SSD "Title" context to cover the whole Titlebar area except
  the parts occupied by buttons. This allows "Drag" and "DoubleClick"
  actions to be de-coupled from buttons. As a result, "Drag" and
  "DoubleClick" actions previously defined against "TitleBar" should now
  come under the "Title" context, for example:
  <mousebind button="Left" action="Drag"><action name="Move"/></mousebind>
• Remove default alt-escape keybind for Exit because too many people have
  exited the compositor by mistake trying to get out of alt-tab cycling
  or similar.
