Detailed Description

the StyleSelector implementation for CSS.

Definition at line 167 of file cssstyleselector.h.

Constructor & Destructor Documentation

CSSStyleSelector() [1/2]

khtml::CSSStyleSelector::CSSStyleSelector	(	DOM::DocumentImpl *	doc,
		QString	userStyleSheet,
		DOM::StyleSheetListImpl *	styleSheets,
		const QUrl &	url,
		bool	_strictParsing
	)

creates a new StyleSelector for a Document.

goes through all StyleSheets defined in the document and creates a list of rules it needs to apply to objects

Also takes into account special cases for HTML documents, including the defaultStyle (which is html only)

Definition at line 226 of file cssstyleselector.cpp.

CSSStyleSelector() [2/2]

khtml::CSSStyleSelector::CSSStyleSelector

(

DOM::CSSStyleSheetImpl *

sheet

)

same as above but for a single stylesheet.
