labwc-theme(5) File Formats Manual labwc-theme(5) 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>/labwc/ * $HOME/.themes/<theme-name>/labwc/ * /usr/share/themes/<theme-name>/labwc/ * /usr/local/share/themes/<theme-name>/labwc/ * /opt/share/themes/<theme-name>/labwc/ * ${XDG_DATA_HOME:-$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 (re- ferred to as buttons). Theme settings specified in themerc can be overridden by creating a 'the- merc-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 name or hexadecimal Red-Green-Blue (RGB) value: color name refers to "X11 color name", for example: 'white', 'grey40', 'pink' and 'peach puff'. More information can be found here: * http://en.wikipedia.org/wiki/Web_colors#X11_color_names * http://en.wikipedia.org/wiki/X11_color_names * https://github.com/labwc/labwc/blob/master/src/common/rgb.txt RGB value * #rrggbb (hexadecimal RGB values) * #rrggbb aaa (same but with decimal alpha value percentage) * #rrggbbaa (same but with inline alpha value in hex encoding) * #rgb (hexadecimal RGB values where #fff is shorthand for #f0f0f0) (since 0.9.0) 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 op- tions are Left, Center and Right. textures Textures determine the visual look of an element. They are specified through a text string with a number of fields. Capitalization is not significant. The format is as follows: (Solid | Gradient <type>) .. where | stands for "or". * Solid means that the background of the texture is filled with a single color. The texture must be accompanied by a single color field. For example: window.*.title.bg: Solid window.*.title.bg.color: #f8f5f2 * Gradient means that the background of the texture is filled with a gradient from one color to another. When Gradient is specified, it must be followed by the gradient's type. It must also be accompa- nied by the fields color and colorTo. Valid gradient types are: (1) Vertical where the gradient goes from the top edge to the bottom (2) SplitVertical where the gradient is split in the middle and goes out toward the top and bottom edges. SplitVertical gradients have two extra, optional color fields: color.splitTo and col- orTo.splitTo. These colors are the light colors used on the far top and bottom of the SplitVertical gradient. When these are omitted, the default values for these are color x 5/4 and colorTo x 17/16. Examples: # Vertical gradient window.*.title.bg: Gradient Vertical window.*.title.bg.color: #658fb5 window.*.title.bg.colorTo: #4d6982 # SplitVertical gradient window.*.title.bg: Gradient SplitVertical window.*.title.bg.color: #658fb5 window.*.title.bg.color.splitTo: #7595b9 window.*.title.bg.colorTo: #4d6982 window.*.title.bg.colorTo.splitTo: #557485 THEME ELEMENTS border.width Line width (integer) of border drawn around window frames. Default is 1. window.titlebar.padding.width Horizontal titlebar padding size, in pixels, between border and first button on the left/right. Default is 0. window.titlebar.padding.height Vertical titlebar padding size, in pixels. Default is 0. window.active.border.color Border color of active window. Default is #aaaaaa. window.inactive.border.color Border color of inactive window. Default is #aaaaaa. window.active.indicator.toggled-keybind.color Status indicator for the ToggleKeybinds action. Can be set to the same value as set for window.active.border.color to disable the status indi- cator. Default is #ff0000. window.active.title.bg Texture for the focused window's titlebar. See texture section above. Default is Solid. window.active.title.bg.color Background color for the focused window's titlebar. See texture section for additional color fields associated with gradients. Default is #e1dedb. window.inactive.title.bg Texture for non-focused windows' titlebars. See texture section above. Default is Solid. window.inactive.title.bg.color Background color for non-focused windows' titlebars. See texture sec- tion for additional color fields associated with gradients. Default is #f6f5f4. window.active.label.text.color Text color for the focused window's titlebar. Default is #000000. window.inactive.label.text.color Text color non-focused windows' titlebars. Default is #000000. window.label.text.justify Specifies how window titles are aligned in the titlebar for both fo- cused and unfocused windows. Type justification. Default is Center. window.button.width Width of a titlebar button, in pixels. Default is 26. window.button.height Height of a titlebar button, in pixels. Default is 26. window.button.spacing Space between titlebar buttons, in pixels. Default is 0. Note: The window.button.hover namespace (below) relates to button hover overlay effects which work with all buttons including svg, png and xbm. The window.button.hover effects are only shown if there is no corresponding hover icon, like close_hover-active.svg. Openbox only supports hover effects rendered behind buttons which makes sense for the xbm format, but not for others. For reference, these are de- fined by window.active|inactive.button.STATE.bg where STATE can be any of pressed, hover and disabled. These are not (yet) supported by labwc and are mentioned here for comparison only. window.button.hover.bg.color Color of the hover effect of a titlebar button. Default is #80808020. window.button.hover.bg.corner-radius Radius of the hover effect of a titlebar button, in pixels. Default is 0. Note: for a circular hover effect, set window.button.width and win- dow.button.height equal and window.button.hover.bg.corner-radius half of them. 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. Default is #000000. 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. Default is #000000. 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. window.active.shadow.size Size of the drop-shadow for the focused window, in pixels. Default is 60. window.inactive.shadow.size Size of drop-shadows for non-focused windows, in pixels.

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 hov- ering 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 "-inac- tive" to align with the respective titlebar colors. For example: "close-ac- tive.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 follow- ing 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] * shade_toggled-inactive.[png|svg] * shade_toggled_hover-active.[png|svg] * shade_toggled_hover-inactive.[png|svg] * desk-active.[png|svg] * desk_hover-active.[png|svg] * desk_hover-inactive.[png|svg] * desk-inactive.[png|svg] * desk_toggled-active.[png|svg] * desk_toggled-inactive.[png|svg] * desk_toggled_hover-active.[png|svg] * desk_toggled_hover-inactive.[png|svg] DEFINITIONS The handle is the window edge decoration at the bottom of the window.
