labwc - actions

Actions are used in menus and keyboard/mouse bindings.

<action name="Close" />

Close top-most window.

<action name="Kill" />

Kill the process associated with the current window by sending it the SIGTERM signal.

<action name="Execute" command="value" />

Execute command. Note that in the interest of backward compatibility, labwc supports <execute> as an alternative to <command> even though openbox documentation states that it is deprecated. Note: Tilde (~) is expanded in the command before passing to execvp().

<action name="Exit" />

Exit labwc.

<action name="Focus" />

Give focus to window under cursor.

<action name="Unfocus" />

Remove focus from the window that is currently focused.

<action name="Raise" />

Restack the current window above other open windows.

<action name="Lower" />

Restack the current window below other open windows.

<action name="Iconify" />

Iconify (minimize) focused window.

<action name="Move" />

Begin interactive move of window under cursor.

<action name="MoveToEdge" direction="value" snapWindows="value" />

Move window until it hits the next edge.

direction [left|up|right|down] Direction in which to move.

snapWindows [yes|no] Move window until it hits an edge of another window or screen edge. If set to "no", only move to the next screen edge. Default is yes.

<action name="Resize" />

Begin interactive resize of window under cursor.

<action name="ResizeRelative" left="" right="" top="" bottom="" />

Resize window relative to its current size. Values of left, right, top or bottom tell how much to resize on that edge of window, positive values grow window, negative shrink window.

<action name="GrowToEdge" direction="value" />

Resize window to fill the space between its edge and any other window edge.

direction [left|up|right|down] Direction in which to grow.

<action name="ShrinkToEdge" direction="value" />

Reverse of GrowToEdge. Shrinks by a maximum of 50%.

direction [left|up|right|down] Direction in which to shrink.

<action name="MoveTo" x="" y="" />

Move to position (x, y).

<action name="ResizeTo" width="" height="" />

Resize window.

width The width to resize the window to in pixels.

height The height to resize the window to in pixels.

<action name="MoveToCursor" />

Move to be centered on cursor. Tries to prevent any part of the window from going off-screen.

<action name="MoveRelative" x="" y="" />

Move window relative to its current position. Positive value of x moves it right, negative left. Positive value of y moves it down, negative up.

<action name="SnapToEdge" direction="value" />

Resize window to fill half the output in the given direction. Supports directions "left", "up", "right", "down" and "center".

<action name="SnapToRegion" region="value" />

Resize and move active window according to the given region. See labwc-config(5) for further information on how to define regions.

<action name="NextWindow" />

Cycle focus to next window.

<action name="PreviousWindow" />

Cycle focus to previous window.

<action name="Reconfigure" />

Re-load configuration and theme files.

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

Show menu. Valid menu names are "root-menu" and "client-menu".

<action name="ToggleDecorations" />

Toggle decorations of focused window.

This is a 3-state action which can be executed multiple times:

•Only the titlebar will be hidden, borders and resize area are kept
•Remaining decorations will be disabled
•Decorations will be shown normally

By disabling the theme configuration 'keepBorder' the first step will be removed and the action only toggles between on and off.

<action name="ToggleFullscreen" />

Toggle fullscreen state of focused window.

<action name="ToggleMaximize" direction="value" />

Toggle maximize state of focused window. Supported directions are "both" (default), "horizontal", and "vertical".

<action name="Maximize" direction="value" />

Maximize focused window. Supported directions are "both" (default), "horizontal", and "vertical".

<action name="ToggleAlwaysOnTop" />

Toggle always-on-top of focused window.

<action name="ToggleAlwaysOnBottom" />

Toggle between layers 'always-on-bottom' and 'normal'. When a window is in the 'always-on-bottom' layer, it is rendered below all other top-level windows. It is anticipated that this action will be useful when defining window-rules for desktop-management tools that do not support the wlr-layer-shell protocol.

<action name="ToggleOmnipresent" />

Toggle omnipresent (visible on all workspaces / sticky) for the focused window.

<action name="ToggleKeybinds" />

Stop handling keybinds other than ToggleKeybinds itself. This can be used to allow A-Tab and similar keybinds to be delivered to Virtual Machines, VNC clients or nested compositors. A second call will restore all original keybinds.

This action will only affect the window that had keyboard focus when the binding was executed. Thus when switching to another window, all the usual keybinds will function again until switching back to the original window. There can be multiple windows with this mode set.

<action name="ToggleTearing" />

Toggles tearing for the focused window.

<action name="FocusOutput" output="HDMI-A-1" />

Give focus to topmost window on given output and warp the cursor to the center of the window. If the given output does not contain any windows, the cursor is centered on the given output.

<action name="MoveToOutput" name="HDMI-A-1" direction="value" />

Moves active window to other output, unless the window state is fullscreen.

If name is specified, the window will be sent directly to the specified output and direction is ignored. If name is omitted, direction may be one of "left", "right", "up" or "down" to indicate that the window should be moved to the next output in that direction (if one exists).

<action name="FitToOutput" />

Resizes active window size to width and height of the output when the window size exceeds the output size.

<action name="GoToDesktop" to="value" wrap="yes" />

Switch to workspace.

to The workspace to switch to. Supported values are "current", "last", "left", "right" or the full name of a workspace or its index (starting at 1) as configured in rc.xml.

wrap [yes|no] Wrap around from last desktop to first, and vice versa. Default yes.

<action name="SendToDesktop" to="value" follow="yes" wrap="yes" />

Send active window to workspace.

to The workspace to send the window to. Supported values are the same as for GoToDesktop.

follow [yes|no] Also switch to the specified workspace. Default yes.

wrap [yes|no] Wrap around from last desktop to first, and vice versa. Default yes.

<action name="VirtualOutputAdd" output_name="value" />

Add virtual output (headless backend).

For example, it can be used to overlay virtual output on real output, but with a different resolution (this can be done with `wlr-randr` or `wdisplays`). After that, virtual output can be selected for screen sharing (casting), effectively sharing only the region of the screen.

It must be noted that overlaying virtual output and real output is not endorsed or explicitly supported by wlroots. For example, after configuring virtual output, real output must be reconfigured as well (for the overlay configuration to work correctly). This is the example configuration:

<keybind key="W-v">
  <action name="VirtualOutputAdd" output_name="ScreenCasting"/>
  <action name="Execute" command='sh -c "wlr-randr --output ScreenCasting --pos 0,0 --scale 2 --custom-mode 3840x2110; wlr-randr --output eDP-1 --pos 0,0 --scale 2 --mode 3840x2160"'/>
</keybind>
<keybind key="W-c">
  <action name="VirtualOutputRemove"/>
</keybind>

Note that the vertical resolution of "ScreenCasting" output is just 50px smaller than "eDP-1" output to cut off bottom panel from screen sharing.

Virtual output is also useful for extending the desktop to (maybe mobile) remote systems like tablets. E.g. simply adding a virtual output, attaching wayvnc to it and running a VNC client on the remote system.

output_name The name of virtual output. Providing virtual output name is beneficial for further automation. Default is "HEADLESS-X".

<action name="VirtualOutputRemove" output_name="value" />

Remove virtual output (headless backend).

output_name The name of virtual output. If not supplied, will remove the last virtual output added.

<action name="AutoPlace" />

Use the automatic placement policy to move the active window to a position on its output that will minimize overlap with other windows.

<action name="Shade" />
<action name="Unshade" />
<action name="ToggleShade" />

Set, unset, or toggle, respectively, the "shaded" state of the active window. When shaded, window contents are hidden, leaving only the titlebar visible. Full-screen windows or those without server-side decorations (including those for which the server-side titlebar has been hidden) are not eligible for shading.

<action name="None" />

If used as the only action for a binding: clear an earlier defined binding.

Actions that execute other actions. Used in keyboard/mouse bindings.

<action name="If">

This action will execute one set of actions if the focused window matches the criteria, or another if it does not.

The arguments are as follows:

<action name="If">
  <query/>
  <then><action/></then>
  <else><action/></else>
</action>

query

Define a query with zero or more conditions. All conditions must be evaluated as true in order for the window to match this query. Multiple queries can be defined.

Pattern matching is done according to glob(7) and is case-insensitive.

Conditions are as follows:

identifier

XDG shell app_id for Wayland clients, WM_CLASS for XWayland clients.

title

XDG shell title for Wayland clients, WM_NAME for XWayland clients.

This argument is optional.

then

A list of actions to be executed if the window matches any query. This argument is optional.

else

A list of actions to be executed if the window does not match any query. This argument is optional.

<action name="ForEach">

Identical to "If" action, but applies to all windows, not just the focused one.
