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

labwc Debian release 0.6.6-1

labwc 0.6.6

Added

- Add `fixedPosition` window-rule property to avoid re-positioning windows
  on reserved-output-space changes (determined by *<margin>* 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 *<margin>* 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
  @jlindgren). 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.

labwc 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).

labwc 0.6.4

Added

- Add support for `ext_idle_notify` protocol.
- Window-switcher: #879 #969
  - Set item-height based on font-height
  - Add theme option:
    - osd.window-switcher.width
    - osd.window-switcher.padding
    - osd.window-switcher.item.padding.x
    - osd.window-switcher.item.padding.y
    - osd.window-switcher.item.active.border.width
- Actions:
  - Add `MoveTo`, `ToggleAlwaysOnBottom`.
  - Add `MoveRelative`, `ResizeRelative`. Written-by: @Ph42oN
  - Add option `wrap` for `GoToDesktop` and `SendToDesktop`
- Add config options `<margin>` to override usable area for panels/docks
  which do not support layer-shell protocol.
- Add `number` attribute to `<desktops>` to simplify configuration.
  Written-by: @Sachin-Bhat
- Window rules: #787 #933
  - Add properties: `skipTaskbar` and `skipWindowSwitcher`
  - Add criteria `title` and `matchOnce`

Fixed

- Support XML CDATA for `<menu><item><action><command>` in order to provide
  backward compatibility with obmenu-generator #972
- Call `wlr_xwayland_surface_set_minimized()` on xwayland window (un)minimize
  to fix blank surface after minimizing fullscreen Steam windows. #958
- Fix focus at the end of drag-and-drop operation respecting
  `<focus><followMouse>` if enabled. #939 #976
- Render xdg-popups above always-on-top layer.
- Do not render On-Screen-Displays on disabled outputs. #914

Changed

- Make `ToggleKeybinds` applicable only to the window that has keyboard focus
  when the action is executed.

labwc 0.6.3

Added

- Add `focus.followMouseRequiresMovement` to allow a stricter
  focus-what-is-under-the-cursor configuration. #862

- Support window-rules including properties and on-first-map actions.
  Any actions in labwc-actions(5) can be used. Only 'serverDecoration'
  has been added as a property so far. Example config:

      <windowRules>
        <windowRule identifier="some-application">
          <action name="Maximize"/>
        </windowRule>
        <windowRule identifier="foo*" serverDecoration="yes|no"/>
      </windowRules>

- Support configuration of window switcher field definitions.
  Issues #852 #855 #879

      <windowSwitcher show="yes" preview="yes" outlines="yes">
        <fields>
          <field content="type" width="25%" />
          <field content="app_id" width="25%" />
          <field content="title" width="50%" />
        </fields>
      </windowSwitcher>

- Add actions:
    - 'Lower' Written-by: @jech
    - 'Maximize'
- Support ext-session-lock protocol. Helped-by: @heroin-moose

- Validate PID before activating XWayland unmanaged surfaces to check that
  the surface trying to grab focus is actually a child of the topmost
  mapped window.
- Respect cursor constraint hints when cursor movement occurs after
  unlocking the pointer. Written-by: @FuzzyQuills Fixes #872
- Fix invisible cursor on startup and output loss/restore.
  Reported-by: @Flrian Fixes #820
- Fix decoration protocol implementation
    - Respect earlier decoration negotiation results via the
      xdg-decoration protocol. Previously setting `<decoration>` to
      `client` would cause applications which prefer server side
      decorations to not have any decorations at all.
      Fixes #297 #831
    - Handle results of kde-server-decoration negotiations
- Fix `<focus><followMouse>` cursor glitches and issues with focus
  switching via Alt-Tab. Issue #830 #849

Changed

- Make `<windowSwitcher>` a toplevel element rather than a child of
  `<core>`
- Default to follow="true" for SendToDesktop action as per Openbox 3.6
  specification.

labwc 0.6.2

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>

Changed

- Filter out wp_drm_lease_device from Xwayland to avoid Electron apps such as
  VS Code and Discord lagging over time. Issue #553. Written-by: @Joshua-Ashton
- Do not switch output on SnapToEdge if view is maximized. Written-by: @Flrian

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

  `<openbox_menu><menu id="root-menu">...</menu></openbox>`. Issue #472
- Allow xdg-desktop-portal-wlr to work out of the box by initializing dbus
  and systemd activation environment. This enables for example OBS Studio

Changed

- src/config/rcxml.c: distinguish between no and unknown font places so
  that `<font>` with no `place` attribute can be added after other font
  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.

labwc 0.5.3

Added

- wlr-output-power-management protocol to enable clients such as wlopm
  Written-by: @bi4k8

Fixed

- Call foreign-toplevel-destroy when unmapping xwayland surfaces because
  some xwayland clients leave unmapped child views around. Although
  handle_destroy() is not called for these, we have to call
  foreign-toplevel-destroy to avoid clients such as panels incorrecly
  showing them.
- Handle xwayland set_override_redirect events to fix weird behaviour with
  gitk menus and rofi.
- Re-focus parent surface on unmapping xwayland unmanaged surfaces
  Fixes #352 relating to JetBrains and Intellij focus issues
  Written-by: Jelle De Loecker
- Do not segfault on missing drag icon. Written-by: @Consolatis
- Fix windows irratically sticking to edges during move/resize.
  Fixes issues #331 and #309

labwc 0.5.2

Compile with wlroots 0.15.1

This is a minor bugfix release mostly to ease packaging by using
system provided wlroots is available (thanks @eli-schwartz)

  xwayland terminal emulators to be resized to a width/height evenly
  divisible by the cell size. Written-by: @jlindgren90

- Restore drag mouse-bindings and proper double-click (issues #258 and
  #259). Written-by: @Consolatis
- Implement cursor input for unmanaged xwayland surfaces outside their
  parent view. Without this menus extending outside the main application
  window do not receive mouse input. Written-by: @jlindgren90
- Allow dragging scrollbar or selecting text even when moving cursor
  outside of the window (issue #241). Written-by: @Consolatis

labwc 0.5.0

Compile with wlroots 0.15.1

This release contains the following two breaking changes:

1. Disabling outputs now causes views to be re-arranged, so in the
   context of idle system power management (for example when using
   swaylock), it is no longer suitable to call wlr-randr {--off,--on}
   to enable/disable outputs.

2. The "Drag" mouse-event and the unmaximize-on-move feature require
   slightly different `<mousebind>` settings to feel natural, so suggest
   updating any local `rc.xml` settings in accordance with
   `docs/rc.xml.all`

As usual, this release contains a bunch of fixes and improvements, of
which the most notable feature-type changes are listed below. A big
thank you to @ARDiDo, @Consolatis and @jlindgren90 for much of the hard
work.

- Render overlay layer popups to support sfwbar (issue #239)

- Support HiDPI on-screen-display images for outputs with different scales

- Reload environment variables on SIGHUPi (issue #227)

- Add client menu

- Allow applications to start in fullscreen

- Add config option `<core><cycleViewPreview>` to preview the contents
  of each view when cycling through them (for example using alt-tab).

- Allow mouse movements to trigger SnapToEdge. When dragging a view, move
  the cursor outside an output to snap in that direction.

- Unmaximize on Move

- Support wlroots environment variable WLR_{WL,X11}_OUTPUTS for running
  in running nested in X11 or a wlroots compositor.

- Support pointer gestures (pinch/swipe)

- Adjust views to account for output layout changes
