## Member Function Documentation

static Glib::RefPtr<SettingsSchemaSource> Gio::SettingsSchemaSource::get_default | ( |  | ) |
| static

Gets the default system schema source.

This function is not required for normal uses of Settings but it may be useful to authors of plugin management systems or to those who want to introspect the content of schemas.

If no schemas are installed, `nullptr` will be returned.

The returned source may actually consist of multiple schema sources from different directories, depending on which directories were given in `XDG_DATA_DIRS` and `GSETTINGS_SCHEMA_DIR`. For this reason, all lookups performed against the default source should probably be done recursively.

Since glibmm 2.32:

Returns
  The default schema source.

GSettingsSchemaSource* Gio::SettingsSchemaSource::gobj | ( |  | ) |

Provides access to the underlying C instance.

const GSettingsSchemaSource* Gio::SettingsSchemaSource::gobj | ( |  | ) | const

Provides access to the underlying C instance.

GSettingsSchemaSource* Gio::SettingsSchemaSource::gobj_copy | ( |  | ) | const

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

Glib::RefPtr<SettingsSchema> Gio::SettingsSchemaSource::lookup | ( | const Glib::ustring& | schema_id,
|  | bool | recursive
| ) |  |

Looks up a schema with the identifier schema_id in source.

This function is not required for normal uses of Settings but it may be useful to authors of plugin management systems or to those who want to introspect the content of schemas.

If the schema isn't found directly in source and recursive is `true` then the parent sources will also be checked.

If the schema isn't found, `nullptr` is returned.

Since glibmm 2.32:

Parameters

  schema_id | A schema ID.
  recursive | `true` if the lookup should be recursive.

Returns
  A new SettingsSchema.

Glib::RefPtr<const SettingsSchema> Gio::SettingsSchemaSource::lookup | ( | const Glib::ustring& | schema_id,
|  | bool | recursive
| ) |  | const

Looks up a schema with the identifier schema_id in source.

This function is not required for normal uses of Settings but it may be useful to authors of plugin management systems or to those who want to introspect the content of schemas.

If the schema isn't found directly in source and recursive is `true` then the parent sources will also be checked.

If the schema isn't found, `nullptr` is returned.

Since glibmm 2.32:

Parameters

  schema_id | A schema ID.
  recursive | `true` if the lookup should be recursive.

Returns
  A new SettingsSchema.

void Gio::SettingsSchemaSource::operator delete | ( | void * | ,
|  | std::size_t |
| ) |  |
| protected

SettingsSchemaSource& Gio::SettingsSchemaSource::operator= | ( | const SettingsSchemaSource& |  | ) |
| delete

void Gio::SettingsSchemaSource::reference | ( |  | ) | const

Increment the reference count for this object.

You should never need to do this manually - use the object via a RefPtr instead.

void Gio::SettingsSchemaSource::unreference | ( |  | ) | const

Decrement the reference count for this object.

You should never need to do this manually - use the object via a RefPtr instead.

## Friends And Related Function Documentation

Glib::RefPtr< Gio::SettingsSchemaSource > wrap | ( | GSettingsSchemaSource * | object,
|  | bool | take_copy = `false`
| ) |  |
| related

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.
