A CSS rule based on a template widget.
This is a CSS rule whose CSS style properties are defined based on properties of a template widget. When modifying the template widget, these changes are reflected on the CSS rule and thus all widgets that have this CSS rule.
Usage example:
Wt::WCssTemplateRule::WCssTemplateRule | ( | const std::string & | selector | ) |
Creates a CSS rule with a given selector.
The selector should be a valid CSS selector.
|
overridevirtual |
Returns the declarations.
This is a semi-colon separated list of CSS declarations.
Implements Wt::WCssRule.
WWidget * Wt::WCssTemplateRule::templateWidget | ( | ) |
Returns the widget that is used as a template.
Various properties of the widget are reflected in the CSS style:
When modifying one of these properties of the returned widget, the rule will be updated accordingly.
