Member Function Documentation

virtual void Wt::WTheme::apply ( WWidget *  widget, WWidget *  child, int  widgetRole  ) const

pure virtual

Applies the theme to a child of a composite widget.

The widgetRole indicates the role that child has within the implementation of the widget.

Implemented in Wt::WCssTheme, and Wt::WBootstrapTheme.

virtual void Wt::WTheme::apply ( WWidget *  widget, DomElement &  element, int  elementRole  ) const

pure virtual

Applies the theme to a DOM element that renders a widget.

The element is a rendered representation of the widget, and may be further customized to reflect the theme.

Implemented in Wt::WCssTheme, and Wt::WBootstrapTheme.

virtual std::string Wt::WTheme::name ( ) const

pure virtual

Returns a theme name.

Returns a unique name for the theme. This name is used by the default implementation of resourcesUrl() to compute a location for the theme's resources.

Implemented in Wt::WCssTheme, and Wt::WBootstrapTheme.

std::string Wt::WTheme::resourcesUrl ( ) const

virtual

Returns the URL where theme-related resources are stored.

The default implementation considers a folder within Wt's resource directory, based on the theme name().

void Wt::WTheme::serveCss ( WStringStream &  out ) const

virtual

Serves the CSS for the theme.

This must serve CSS declarations for the theme.

The default implementation serves all the styleSheets().

virtual std::vector<WLinkedCssStyleSheet> Wt::WTheme::styleSheets ( ) const

pure virtual

Returns a vector with stylesheets for the theme.

This should return a vector with stylesheets that implement the theme. This list may be tailored to the current user agent, which is read from the application environment.

Implemented in Wt::WCssTheme, and Wt::WBootstrapTheme.

virtual std::string Wt::WTheme::utilityCssClass ( int  utilityCssClassRole ) const

pure virtual

Returns a generic CSS class name for the chosen role.
