 The
AG_StyleSheet interface allows Agar GUI style attributes to be loaded from a cascading
style sheet.
Agar style sheets use a particular syntax.
Style sheets contain blocks of attributes which are applicable to specific
Agar widget classes (and possibly, specific widget states as well).
For example:
AG_Button {
# Set colors for default state
color: rgb(125,125,125);
text-color: rgb(0,0,0);
# Set colors for "disabled" state
color#disabled: rgb(200,200,200);
text-color#disabled: rgb(125,125,125);
# Set colors for mouse hover state
color#hover: rgb(200,250,200);
text-color#hover: rgb(125,150,125);
}

By default, a widget instance inherits its style attributes from its parent.
The syntax allows certain attributes, such as "font-size" and "color" to
be specified in relation to the parent.
For example:
font-size: 50%; # Half of parent font size
color: hsv(100%,50%,100%); # Half of parent saturation
color: hsv(100%,100%,75%); # 3/4 of parent value

The generic
AG_Widget class defines the basic attributes "font-family", "font-size", "font-weight",
"font-style", "color", "text-color", "line-color", "shape-color" and
"border-color".
For a full description of those attributes, refer to the
STYLING section of
AG_Widget(3). Other Agar widget classes may define their own style attributes (these
should be documented under the
STYLE PROPERTIES section of the widget's manual page).
