◆ Language() [4/5]
| Pango::Language::Language |
( |
| ) |
|
Constructs an empty language tag.
◆ Language() [5/5]
| Pango::Language::Language |
( |
const Glib::ustring & |
language | ) |
|
Constructs a Pango::Language object from a RFC-3066 format language tag.
This function first canonicalizes the string by converting it to lowercase, mapping '_' to '-', and stripping all characters other than letters and '-'.
◆ get_scripts()
Determines the scripts used to write this language.
If nothing is known about the language tag then an empty vector is returned. The list of scripts returned starts with the script that the language uses most and continues to the one it uses least.
Most languages use only one script for writing, but there are some that use two (Latin and Cyrillic for example), and a few use three (Japanese for example). Applications should not make any assumptions on the maximum number of scripts returned though, except that it is a small number.
The includes_script() function uses this function internally.
- Note
- While the return value is declared as
Pango::Script, the returned values are from the GUnicodeScript enumeration, which may have more values. Callers need to handle unknown values.
- Returns
- A vector of Script values.
- Since pangomm 2.14:
◆ get_string()
| Glib::ustring Pango::Language::get_string |
( |
| ) |
const |
Gets a RFC-3066 format string representing the given language tag.
- Returns
- A string representing the language tag. An empty string is returned if the language tag is empty.
◆ get_type()
Get the GType for this class, for use with the underlying GObject type system.
◆ gobj() [1/2]
Provides access to the underlying C instance.
◆ gobj() [2/2]
Provides access to the underlying C instance.
◆ gobj_copy()
Provides access to the underlying C instance. The caller is responsible for freeing it. Use when directly setting fields in structs.
◆ includes_script()
| bool Pango::Language::includes_script |
( |
Script |
script | ) |
const |
Determines if script is one of the scripts used to write language.
The returned value is conservative; if nothing is known about the language tag language, true will be returned, since, as far as Pango knows, script might be used to write language.
This routine is used in Pango's itemization process when determining if a supplied language tag is relevant to a particular section of text. It probably is not useful for applications in most circumstances.
This function uses get_scripts() internally.
- Since pangomm 1.4:
- Parameters
-
- Returns
true if script is one of the scripts used to write language or if nothing is known about language (including the case that language is nullptr), false otherwise.
◆ matches()
| bool Pango::Language::matches |
( |
const Glib::ustring & |
range_list | ) |
const |
Checks if a language tag matches one of the elements in a list of language ranges.
A language tag is considered to match a range in the list if the range is '*', the range is exactly the tag, or the range is a prefix of the tag, and the character after it in the tag is '-'.
- Parameters
-
| range_list | A list of language ranges, separated by ';', ':', ',', or space characters. Each element must either be '*', or a RFC 3066 language range canonicalized as by from_string(). |
- Returns
true if a match was found.
◆ operator=() [1/2]
◆ operator=() [2/2]
◆ swap()
◆ swap()
- Parameters
-
| lhs | The left-hand side |
| rhs | The right-hand side |
◆ wrap()
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.
