__init__(self, selectorText=None, parentRule=None, readonly=False)
(Constructor)

source code 
initializes SelectorList with optional selectorText

(Index assignment operator)

source code 

overwrites ListSeq.__setitem__

Any duplicate Selectors are not removed.

append(self, newSelector)

source code

  • NO_MODIFICATION_ALLOWED_ERR - (self) Raised if this rule is readonly.

appendSelector(self, newSelector)

source code

Parameters:
  • newSelector - comma-separated list of selectors or a tuple of (selectorText, dict-of-namespaces)
Returns:
New Selector or None if newSelector is not wellformed.
Raises:
  • NAMESPACE_ERR - (self) Raised if the specified selector uses an unknown namespace prefix.

Property Details [hide private]

length

The number of Selector elements in the list.
Get Method:
unreachable(self)

_namespaces

if this SelectorList is attached to a CSSStyleSheet the namespaces of that sheet are mirrored here. While the SelectorList (or parentRule(s) are not attached the namespaces of all children Selectors are used.
Get Method:
__getNamespaces(self) - uses children namespaces if not attached to a sheet, else the sheet's ones

parentRule

(DOM) The CSS rule that contains this SelectorList or None if this SelectorList is not attached to a CSSRule.
Get Method:
unreachable(self)

selectorText
