Detailed Description

Abstract rule in a CSS style sheet.

A rule presents CSS style properties that are applied to a selected set of elements.

Use WCssTemplateRule if you would like to use a widget as a template for specifying (and updating) a style rule, using the widgets style properties, or WCssTextRule if you wish to directly specify the CSS declarations.

declarations()

virtual std::string Wt::WCssRule::declarations ( )

pure virtual

Returns the declarations.

This is a semi-colon separated list of CSS declarations.

Implemented in Wt::WCssTemplateRule, and Wt::WCssTextRule.

setSelector()

void Wt::WCssRule::setSelector

(

const std::string &

selector

)

Sets the selector.
