Detailed Description

A Pango::AttrList represents a list of attributes that apply to a section of text.

The attributes are, in general, allowed to overlap in an arbitrary fashion, however, if the attributes are manipulated only through Pango::AttrList::change(), the overlap between properties will meet stricter criteria.

Since the Pango::AttrList structure is stored as a linear list, it is not suitable for storing attributes for large amounts of text. In general, you should not use a single Pango::AttrList for more than one paragraph of text.

When obtaining an AttrList, you should check that it is valid. For instance, if(attrlist).

Pango::AttrList::AttrList ( const Glib::ustring &  markup_text, gunichar  accel_marker = 0  )

explicit

Constructs an attribute list by parsing a marked-up text (see markup format).

If accel_marker is nonzero, the given character will mark the character following it as an accelerator. For example, the accel marker might be an ampersand or underscore. All characters marked as an accelerator will receive a Pango::UNDERLINE_LOW attribute. Two accel_marker characters following each other produce a single literal accel_marker character.

Parameters

markup_text	Markup to parse (see markup format).
accel_marker	Character that precedes an accelerator, or 0 for none.

Pango::AttrList::AttrList	(	const Glib::ustring &	markup_text,
		gunichar	accel_marker,
		Glib::ustring &	text,
		gunichar &	accel_char
	)

Constructs an attribute list by parsing a marked-up text (see markup format).

text is set to the plaintext string. If accel_marker is nonzero, the given character will mark the character following it as an accelerator. For example, the accel marker might be an ampersand or underscore. All characters marked as an accelerator will receive a Pango::UNDERLINE_LOW attribute. The first character so marked will be returned in accel_char. Two accel_marker characters following each other produce a single literal accel_marker character.

Parameters

markup_text	Markup to parse (see markup format).
accel_marker	Character that precedes an accelerator, or 0 for none.
text	Return location for text with tags stripped.
accel_char	Return location for accelerator char.

noexcept

void Pango::AttrList::splice	(	AttrList&	other,
		int	pos,
		int	len
	)

This function opens up a hole in list, fills it in with attributes from the left, and then merges other on top of the hole.

This operation is equivalent to stretching every attribute that applies at position pos in list by an amount len, and then calling change() with a copy of each attribute in other in sequence (offset in position by pos).

This operation proves useful for, for instance, inserting a pre-edit string in the middle of an edit buffer.

Parameters

other	Another Pango::AttrList.
pos	The position in list at which to insert other.
len	The length of the spliced segment. (Note that this must be specified since the attributes in other may only be present at some subsection of this range).

void Pango::AttrList::swap ( AttrList&  other )

noexcept

Parameters

lhs	The left-hand side

A Glib::wrap() method for this object.

Parameters

object	The C instance.
take_copy	False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns

A C++ instance that wraps this C instance.
