 javax.swing.text.html.CSS
| CSS | | public class CSS implements Serializable(Code) | | Defines a set of
CSS attributes
as a typesafe enumeration. The HTML View implementations use
CSS attributes to determine how they will render. This also defines
methods to map between CSS/HTML/StyleConstants. Any shorthand
properties, such as font, are mapped to the intrinsic properties.
The following describes the CSS properties that are suppored by the
rendering engine:
- font-family
- font-style
- font-size (supports relative units)
- font-weight
- font
- color
- background-color (with the exception of transparent)
- background-image
- background-repeat
- background-position
- background
- background-repeat
- text-decoration (with the exception of blink and overline)
- vertical-align (only sup and super)
- text-align (justify is treated as center)
- margin-top
- margin-right
- margin-bottom
- margin-left
- margin
- padding-top
- padding-right
- padding-bottom
- padding-left
- border-style (only supports inset, outset and none)
- list-style-type
- list-style-position
The following are modeled, but currently not rendered.
- font-variant
- background-attachment (background always treated as scroll)
- word-spacing
- letter-spacing
- text-indent
- text-transform
- line-height
- border-top-width (this is used to indicate if a border should be used)
- border-right-width
- border-bottom-width
- border-left-width
- border-width
- border-top
- border-right
- border-bottom
- border-left
- border
- width
- height
- float
- clear
- display
- white-space
- list-style
Note: for the time being we do not fully support relative units,
unless noted, so that
p { margin-top: 10% } will be treated as if no margin-top was specified.

Convert a set of HTML attributes to an equivalent
set of CSS attributes.
Parameters:
AttributeSet - containing the HTML attributes. |
| baseFontSizeIndex | | static int baseFontSizeIndex(Code) | | |
| calculateTiledLayout | | static void calculateTiledLayout(LayoutIterator iter, int targetSpan)(Code) | | Calculate a tiled layout for the given iterator.
This should be done collapsing the neighboring
margins to be a total of the maximum of the two
neighboring margin areas as described in the CSS spec.
|
| calculateTiledRequirements | | static SizeRequirements calculateTiledRequirements(LayoutIterator iter, SizeRequirements r)(Code) | | Calculate the requirements needed to tile the requirements
given by the iterator that would be tiled. The calculation
takes into consideration margin and border spacing.
