Member Function Documentation

virtual size_t cwidget::fragment_container::calc_max_width	(	size_t	first_indent,
		size_t	rest_indent
	)			const [pure virtual]

Actually calculate the maximum width.

Implemented in cwidget::_sequence_fragment.

virtual size_t cwidget::fragment_container::calc_trailing_width	(	size_t	first_indent,
		size_t	rest_indent
	)			const [pure virtual]

Actually calculate the trailing width.

Implemented in cwidget::_sequence_fragment.

virtual bool cwidget::fragment_container::calc_final_newline

(

)

const [pure virtual]

Actually calculate the final-nl status.

Implemented in cwidget::_sequence_fragment.

size_t cwidget::fragment_container::max_width	(	size_t	first_indent,
		size_t	rest_indent
	)			const [inline, virtual]

Parameters:

first_indent

the indentation of the first line, relative to a baseline (which may be outside this fragment).

Parameters:

rest_indent

the indentation of any other lines.

Returns:

the maximum length of any line in this fragment. Any call to layout() with a width greater than this maximum length will produce the same result.

Implements cwidget::fragment.

size_t cwidget::fragment_container::trailing_width	(	size_t	first_indent,
		size_t	rest_indent
	)			const [inline, virtual]

Parameters:

first_indent

the indentation of the first line.

Parameters:

rest_indent

the indentation of any other lines.

Returns:

the length of any "trailing" line in the fragment, including indentation.

Implements cwidget::fragment.

bool cwidget::fragment_container::final_newline

(

)

const [inline, virtual]

Returns:

true if this fragment ends in a newline.

Implements cwidget::fragment.
