Typedef Documentation

◆ CssLength

typedef int CssLength

Lengths are represented as int in the following way: 

*
*    | <------   integer value   ------> |
*
*    +---+ - - - +---+---+- - - - - -+---+---+---+---+
*    |          integer part             |   type    |
*    +---+ - - - +---+---+- - - - - -+---+---+---+---+
*    | integer part  | decimal fraction  |   type    |
*    +---+ - - - +---+---+- - - - - -+---+---+---+---+
*     n-1          15  14              3   2  1   0
*
*    | <------ fixed point value ------> |
*
*

where type is one of the CSS_LENGTH_TYPE_* values. CSS_LENGTH_TYPE_PX values are stored as 29 bit signed integer, all other types as fixed point values.

◆ CssValueType

enum CssValueType
Enumerator
CSS_TYPE_INTEGER 

This type is only used internally, for x-* properties.

CSS_TYPE_ENUM 

Value is i, if represented by enum_symbols[i].

CSS_TYPE_MULTI_ENUM 

For all enum_symbols[i], 1 << i are combined.

CSS_TYPE_LENGTH_PERCENTAGE 

<length> or <percentage>.

Represented by CssLength.

CSS_TYPE_LENGTH 

<length>, represented as CssLength.

Note: In some cases, CSS_TYPE_LENGTH is used instead of CSS_TYPE_LENGTH_PERCENTAGE, only because Dw cannot handle percentages in this particular case (e.g. 'margin-*-width').

CSS_TYPE_SIGNED_LENGTH 

As CSS_TYPE_LENGTH but may be negative.

CSS_TYPE_LENGTH_PERCENTAGE_NUMBER 
CSS_TYPE_AUTO 

Represented as CssLength of type CSS_LENGTH_TYPE_AUTO.

CSS_TYPE_COLOR 

Represented as integer.

CSS_TYPE_FONT_WEIGHT 

this very special and only used by 'font-weight'

CSS_TYPE_STRING 

<string>

CSS_TYPE_SYMBOL 

Symbols, which are directly copied (as opposed to CSS_TYPE_ENUM and CSS_TYPE_MULTI_ENUM).

Used for 'font-family'.

CSS_TYPE_URI 

<uri>

CSS_TYPE_BACKGROUND_POSITION 
CSS_TYPE_UNUSED 

Not yet used.

Will itself get unused some day.
