Gio::SettingsSchemaSource::SettingsSchemaSource |
( |
| ) |

delete |
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.
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::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.
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.
