NAME

       labwc - theme files

THEME

       The theme engine aims to be compatible with openbox and themes will be searched for in the following
       order:

       •   ${XDG_DATA_HOME:-$HOME/.local/share}/themes/<theme-name>/openbox-3/
       •   $HOME/.themes/<theme-name>/openbox-3/
       •   /usr/share/themes/<theme-name>/openbox-3/
       •   /usr/local/share/themes/<theme-name>/openbox-3/
       •   /opt/share/themes/<theme-name>/openbox-3/

       When $XDG_DATA_HOME is defined, it replaces (rather than augments) $HOME/.local/share. The same is the
       case for $XDG_DATA_DIRS and /usr/share/.

       Choosing a theme is done by editing the <name> key in the <theme> section of the rc.xml configuration
       file (labwc-config(5)).

       A theme consists of a themerc file and optionally some titlebar icons (referred to as buttons).

       Theme settings specified in themerc can be overridden by creating a 'themerc-override' file in the
       configuration directory, which is normally $HOME/.config/labwc/ but can be a few other locations as
       described in labwc-config(5).

DATA TYPES

       color
           Colors can be specified by either of the following:
           •   #rrggbb (hexadecimal RGB values)
           •   #rrggbb aaa (same but with decimal alpha value percentage)
           •   #rrggbbaa (same but with inline alpha value in hex encoding)

           Note: the #rrggbb aaa notation is deprecated starting from labwc 0.7.2 and may be removed in future
           releases.

       justification
           Justification determines the horizontal alignment of text. Valid options are Left, Center and Right.

Note: Button elements (i.e. window.[in]active.button.*) may be defined uniquely for each type of button
("menu", "iconify", "max", "shade", "desk" or "close") by appending the type after the "button" node. For
example:

• window.active.button.iconify.unpressed.image.color indicates the color of the iconify button for
active windows; while

• window.inactive.button.close.unpressed.image.color indicates the color of the close button for
inactive windows.

This syntax is not documented by Openbox, but is supported and is used by many popular themes. For the
sake of brevity, these elements are not listed here, but all are supported.

BUTTONS

       The images used for the titlebar icons are referred to as buttons.

       The image formats listed below are supported. They are listed in order of precedence, where the first
       format in the list is searched for first.

       •   png
       •   svg
       •   xbm

       By default, buttons are 1-bit xbm (X Bitmaps). These are masks where 0=clear and 1=colored. The xbm image
       files are placed in the same directory as the themerc file within a particular theme. The following xbm
       buttons are supported:

       •   max.xbm
       •   iconify.xbm
       •   close.xbm
       •   menu.xbm
       •   max_toggled.xbm
       •   desk.xbm
       •   desk_toggled.xbm
       •   shade.xbm
       •   shade_toggled.xbm

       Additional icons can be defined to be shown when the mouse pointer is hovering over the button in
       question:

       •   max_hover.xbm
       •   iconify_hover.xbm
       •   close_hover.xbm
       •   menu_hover.xbm
       •   max_toggled_hover.xbm
       •   desk_hover.xbm
       •   desk_toggle_hover.xbm
       •   shade_hover.xbm
       •   shade_toggle_hover.xbm

       One advantage of xbm buttons over other formats is that they change color based on the theme. Other
       formats use the suffices "-active" and "-inactive" to align with the respective titlebar colors. For
       example: "close-active.png"

       For compatibility reasons, the following alternative names are supported for xbm files:

       •   max_hover_toggled.xbm for max_toggled_hover.xbm

       When using png or svg icons, for a full theme experience all of the following icons should be added:

       •   close-active.[png|svg]
       •   close_hover-active.[png|svg]
       •   close_hover-inactive.[png|svg]
       •   close-inactive.[png|svg]
       •   iconify-active.[png|svg]
       •   iconify_hover-active.[png|svg]
       •   iconify_hover-inactive.[png|svg]
       •   iconify-inactive.[png|svg]
       •   max-active.[png|svg]
       •   max_hover-active.[png|svg]
       •   max_hover-inactive.[png|svg]
       •   max-inactive.[png|svg]
       •   max_toggled-active.[png|svg]
       •   max_toggled_hover-active.[png|svg]
       •   max_toggled_hover-inactive.[png|svg]
       •   max_toggled-inactive.[png|svg]
       •   menu-active.[png|svg]
       •   menu_hover-active.[png|svg]
       •   menu_hover-inactive.[png|svg]
       •   menu-inactive.[png|svg]
       •   shade-active.[png|svg]
       •   shade_hover-active.[png|svg]
       •   shade_hover-inactive.[png|svg]
       •   shade-inactive.[png|svg]
       •   shade_toggled-active.[png|svg]
