Xport Interface: stylesheet_item::operator <<

For a derived stylesheet_rule, Inserts a declaration into the rule.

stylesheet_item& stylesheet_itemoperator << (
  const declaration& decl
);

Parameters

decl

A declaration object.

Returns

Returns a reference to the stylesheet_item object. Thus, this operation can be chained for multiple insertions.

Remarks

This operation is relevent only when called on a derived stylesheet_rule. When called on a derived stylesheet_import or stylesheet_comment object, this operation does nothing.

Although stylesheet_item's insert() operations are overridden and implemented in stylesheet_rule, this operation is implemented in stylesheet_item, and an example will be given here.

Complexity

Logarithmic

Example

#include "xhtml_doc.h"
#include <iostream>

int main(int argc, char* argv[])
{
  using namespace Xport;

  stylesheet ss;

  // insert a few rules
  ss  << (stylesheet_rule("h1") << declaration(css::color, "red") << declaration
  (text_align, "center"))
      << (stylesheet_rule("p") << declaration(padding_left, "5px") << declaration(
      margin_top, "10px"))
      << (stylesheet_rule("#footer") << declaration(css::height, "50px") <<
      declaration(css::border, "thin solid green"));

  // write the stylesheet to cout
  stylesheet_formatter fmtr(std::cout);
  fmtr << ss;
}
