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/

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.

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).

	Colors can be specified by hexadecimal RGB values in the format #rrggbb.

	compatibility.

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 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.

# 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
- menu.xbm

More will be supported later.

Note: menu.xbm is not part of openbox-3.6 spec

# 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.
