## Description

GdictContext is an interface used to uniformly access dictionary transport objects. Each implementation of GdictContext must provide functions for accessing the list of databases available on a dictionary source and the available matching strategies; a function for retrieving all words matching a given string, inside one (or more) of those databases and using one of those strategies; a function for querying one (or more) of those databases for a definition of a word.

Implementations of the GdictContext interface should query their dictionary sources asynchronously; methods of the GdictContext interface should return immediately, and each time a new database, strategy, match or definition has been found, a signal should be fired by those implementations.

## Functions

### gdict_context_set_local_only ()

    void
    gdict_context_set_local_only (GdictContext *context,
                                  gboolean local_only);

Sets whether only local resources will be used when querying for databases, strategies, matches or definitions.

#### Parameters

context | a GdictContext |
local_only | `TRUE` if only local resources will be used |

Since 1.0

### gdict_context_get_local_only ()

    gboolean
    gdict_context_get_local_only (GdictContext *context);

Gets whether only local resources will be used when querying.

#### Parameters

context | a GdictContext |

#### Returns

`TRUE` if only local resources will be used.

Since 1.0

                                    GError **error);

Query `context` for the list of databases available. Each time a database is found, the "database-found" signal is fired.

#### Parameters

context | a GdictContext |
error | return location for a GError, or `NULL` |

#### Returns

`TRUE` if the query was successfully started.

Since 1.0

### gdict_context_lookup_strategies ()

                                     GError **error);

Query `context` for the list of matching strategies available. Each time a new strategy is found, the "strategy-found" signal is fired.

`TRUE` if the query was successfully started.

Since 1.0

### gdict_context_match_word ()
