labwc-theme(5) File Formats Manual labwc-theme(5)

labwc - theme files

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).

color

Colors can be specified by either of the following:
•#rrggbb (hexadecimal RGB values)
•#rrggbb aaa (same but with decimal alpha value)

window.inactive.button.unpressed.image.color

Color of the images in titlebar buttons in their default, unpressed, state. This element is for non-focused windows.

Note: The button elements (i.e. window.[in]active.button.*) support defining different types of buttons individually by inserting the type ("menu", "iconify", "max" and "close") after the button node. For example: window.active.button.iconify.unpressed.image.color This syntax is not documented on the openbox.org wiki, but is supported by openbox and is used by many popular themes. For the sake of brevity, these elements are not listed here, but are supported.

border.color

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

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

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]

The handle is the window edge decoration at the bottom of the window.
