Pango::AttrList Class Reference

List of all members.

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).

Constructor & Destructor Documentation

Pango::AttrList::AttrList (  ) 
 

Pango::AttrList::AttrList ( PangoAttrList*  gobject,
bool  make_a_copy = true
[explicit]
 

Pango::AttrList::AttrList ( const AttrList other  ) 
 

Pango::AttrList::~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.


Member Function Documentation

void Pango::AttrList::change ( Attribute attr  ) 
 

AttrIter Pango::AttrList::get_iter (  ) 
 

Create a iterator initialized to the beginning of the list.

Returns:
A new Pango::Iterator. list must not be modified until this iterator is freed with pango_attr_iterator_destroy().

const PangoAttrList* Pango::AttrList::gobj (  )  const [inline]
 

Provides access to the underlying C instance.

PangoAttrList* Pango::AttrList::gobj (  )  [inline]
 

Provides access to the underlying C instance.

PangoAttrList* Pango::AttrList::gobj_copy (  )  const
 

Provides access to the underlying C instance. The caller is responsible for freeing it. Use when directly setting fields in structs.

void Pango::AttrList::insert ( Attribute attr  ) 
 

void Pango::AttrList::insert_before ( Attribute attr  ) 
 

Pango::AttrList::operator bool (  ) 
 

Tests whether the AttrList is valid.

AttrList& Pango::AttrList::operator= ( const AttrList other  ) 
 

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

This function splices attribute list other into list .

This operation is equivalent to stretching every attribute that applies at position pos in list by an amount len , and then calling pango_attr_list_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 preedit 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  ) 
 


Friends And Related Function Documentation

void swap ( AttrList lhs,
AttrList rhs
[related]
 

Parameters:
lhs The left-hand side
rhs The right-hand side

Pango::AttrList wrap ( PangoAttrList*  object,
bool  take_copy = false
[related]
 

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.
