CSS::DOM::Value::List - CSSValueList class for CSS::DOM


Version 0.17


  # ...


This module implements objects that represent CSS list property values. It implements the DOM CSSValueList interface.

You can access the individual elements of the list using the "item" and "length" methods, or by using it as an array ref.


If you need the constructor, it's below the object methods. Normally you would get an object via CSS::DOM::Style's "getPropertyCSSValue" method.

CSSValue Interface

Returns a string representation of the attribute. Pass an argument to set it.

CSSValueList Interface

Returns the 'primitive' value at the given index.
Returns the number of values in the list.


You probably don't need to call this, but here it is anyway:

  $val = new CSS::DOM::Value::List:: %args;

The hash-style arguments are as follows. Only "values" is required.

This must be an array ref containing the individual values to be stored in the list. The individual elements can be value objects or array refs of arguments to pass to "new CSS::DOM::Value::Primitive". E.g.,

     [type => CSS_PX, value => 20],
     [type => CSS_PERCENTAGE, value => 50],
     [type => CSS_PERCENTAGE, value => 50],
     [type => CSS_PX, value => 50],
CSS code used for serialisation. This will make reading "cssText" faster at least until the value is modified.
The value separator used in serialisation. This is usually ' ' or ', '. An empty string or "undef" is treated as a space.
The style object that owns this value; if this is omitted, then the value is read-only. The value object holds a weak reference to the owner.
The name of the CSS property to which this value belongs. "cssText" uses this to determine how to parse text passed to it. This does not apply to the sub-values of colours, counters and rects, but it does apply to individual elements of a list value.
