Xport Interface: formatter::layout_style
Sets or retrieves the layout style for a specific tag.
tag_layout_style formatter::layout_style(1st Variety
xhtml_tag_enum tg
);
void layout_style(2st Variety
xhtml_tag_enum tg,
tag_layout_style tls
);
Parameters
tg
A xhtml_tag_enum enumerator which specifies the tag which to set the layout style.
tls
A tag_layout_style enumerator which specifies the layout style to apply to the specified tag.
Returns
In the first variety, returns a tag_layout_style enumerator which reveals the layout style of the specified tag.
Remarks
This operation is used to set or to determine the tag layout style
of a specific tag.
The first variety formats and writes a document object. The second variety formats and writes a markup object. Where these
objects are written is determined by the output stream or file which was specified in the formatter's constructor.
Complexity
Logarithmic
Example
1st Variety
#include "xhtml_doc.h"
#include <iostream>
int main(int argc, char* argv[])

case block_level_layout:
lstyle = "block level"; break;
case pre_layout:

}

2nd Variety

formatter fmtr(std::cout);

std::cout << "\n\n";
std::cout << "Changing li tag style to newline after end tag.";
std::cout << "\n\n";
