labwc - Theme specification

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/

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 xbm icons.

DATA TYPES

color RGB values

Colors can be specified by hexadecimal RGB values in the format #rrggbb. Other formats will be supported later for better openbox theme compatibility.

justification

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

THEME ELEMENTS

Line width (integer) of border border drawn around window frames. Default is 1.

padding.height

Vertical padding size, used for spacing out elements in the window decorations. Default is 3.

menu.overlap.x

Horizontal overlap in pixels between submenus and their parents. A positive value move submenus over the top of their parents, whereas a negative value creates a gap between submenus and their parents. Default is 0.

window.label.text.justify

Specifies how window titles are aligned in the titlebar for both focused and unfocused windows. Type justification. Default Left.

window.active.button.unpressed.image.color

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

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 ("iconify", "max" and "close") after the button node. For example: window.active.button.iconify.unpressed.image.color This syntax is not 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.

menu.items.bg.color

Background color of inactive menu items

menu.items.text.color

Text color of inactive menu item

menu.items.active.bg.color

Background color of active menu items

osd.bg.color

Background color of on-screen-display

osd.label.text.color

border.color

Set all border colors. This is obsolete, but supported for backward compatibility as some themes still contain it.

BUTTONS

The images used for the titlebar 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 within your theme as the themerc file. Here are all the possible xbm files looked for:

•max.xbm

•iconify.xbm

•close.xbm

More will be supported later.

DEFINITIONS

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

DERIVED DIMENSIONS

The window title bar height is equal to the vertical font extents of the title. Padding will be added to this later.
