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_error_quark ()

GQuark
gdict_context_error_quark (void);

Interface defintion


GdictDatabase

typedef struct _GdictDatabase GdictDatabase;

A GdictDatabase represents a database inside a dictionary source.

The GdictDatabase structure is private and should only be accessed using the available functions.


GdictDefinition

typedef struct _GdictDefinition GdictDefinition;

A GdictDefinition represents a single definition for the searched word.

The GdictDefinition structure is private and should only be accessed using the available functions.


GdictMatch

typedef struct _GdictMatch GdictMatch;

A GdictMatch represents a single match for the searched word.

The GdictMatch structure is private and should only be accessed using the available functions.


GdictStrategy

typedef struct _GdictStrategy GdictStrategy;

A GdictStrategy represents a matching strategy implemented by a dictionary source.

The GdictStrategy structure is private and should only be accessed using the available functions.

The “local-only” property

  “local-only”               gboolean

Whether the context uses only local dictionaries or not.

void
user_function (GdictContext  *context,
               GdictDatabase *database,
               gpointer       user_data)

This signal is emitted when a database request has found a database.

Parameters

context

the object which received the signal

 

database

a GdictDatabase

 

user_data

user data set when the signal handler was connected.

context

the object which received the signal

 

definition

a GdictDefinition

 

user_data

user data set when the signal handler was connected.

 

Flags: Run Last

Since: 1.0

user data set when the signal handler was connected.

 

Flags: Run Last

Since: 1.0
