The PangoLogAttr
structure stores information about the attributes of a
single character.
Structure members
is_line_break |
If set, can break line in front of character. |
is_mandatory_break |
If set, must break line in front of character. |
is_char_break |
If set, can break here when doing character wrapping. |
is_white |
Is whitespace character. |
is_cursor_position |
If set, cursor can appear in front of character. i.e. this is a grapheme boundary, or the first character in the text. This flag implements Unicode’s Grapheme Cluster Boundaries semantics. |
is_word_start |
Is first character in a word. |
is_word_end |
Is first non-word char after a word
Note that in degenerate cases, you could have both |
is_sentence_boundary |
Is a sentence boundary.
There are two ways to divide sentences. The first assigns all
inter-sentence whitespace/control/format chars to some sentence,
so all chars are in some sentence; |
is_sentence_start |
Is first character in a sentence. |
is_sentence_end |
Is first char after a sentence.
Note that in degenerate cases, you could have both |
backspace_deletes_character |
If set, backspace deletes one character
rather than the entire grapheme cluster. This field is only meaningful
on grapheme boundaries (where |
is_expandable_space |
Is a whitespace character that can possibly be expanded for justification purposes. (Since: 1.18) |
is_word_boundary |
Is a word boundary, as defined by UAX#29. More specifically, means that this is not a position in the middle of a word. For example, both sides of a punctuation mark are considered word boundaries. This flag is particularly useful when selecting text word-by-word. This flag implements Unicode’s Word Boundaries semantics. (Since: 1.22) |
break_inserts_hyphen |
When breaking lines before this char, insert a hyphen. Since: 1.50 |
break_removes_preceding |
When breaking lines before this char, remove the preceding char. Since 1.50 |
