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.

a strategy name to use for matching, or NULL for
the default strategy
|

|
Since 1.0
gboolean gdict_context_define_word (GdictContext *context, const gchar *database, const gchar *word, GError **error);
Query context for a list of definitions of word inside database. Each
time a new definition is found, the "definition-found" signal is fired.
context : |
a GdictContext |
database : |
a database name to search into, or NULL for the
default database
|
word : |
the word to search |
error : |
return location for a GError, or NULL
|
| Returns : | TRUE if the query was successfully sent.
