    #define ANJUTA_PLUGIN_MANAGER_ERROR            (anjuta_plugin_manager_error_quark())

### struct AnjutaPluginManagerClass

    struct AnjutaPluginManagerClass {
    	GObjectClass parent_class;

    	/* Signals */
    	void(* plugin_activated) (AnjutaPluginManager *self,
    							  AnjutaPluginDescription* plugin_desc,

    	void(* plugin_deactivated) (AnjutaPluginManager *self,
    								AnjutaPluginDescription* plugin_desc,
    								GObject *plugin);
    };

### enum AnjutaPluginManagerError

    typedef enum {
    	ANJUTA_PLUGIN_MANAGER_MISSING_FACTORY,
    	ANJUTA_PLUGIN_MANAGER_ERROR_UNKNOWN
    } AnjutaPluginManagerError;

`ANJUTA_PLUGIN_MANAGER_MISSING_FACTORY` | The factory for the plugin couldn't be found
`ANJUTA_PLUGIN_MANAGER_ERROR_UNKNOWN` | Unknown error

### AnjutaPluginManagerPriv

    typedef struct _AnjutaPluginManagerPriv AnjutaPluginManagerPriv;

### anjuta_plugin_manager_activate_plugins ()

    void                anjuta_plugin_manager_activate_plugins
                                                            (AnjutaPluginManager *plugin_manager,
                                                             GList *plugin_descs);

### anjuta_plugin_manager_error_quark ()

    GQuark              anjuta_plugin_manager_error_quark   (void);

### anjuta_plugin_manager_get_active_plugin_objects ()

    GList *             anjuta_plugin_manager_get_active_plugin_objects
                                                            (AnjutaPluginManager *plugin_manager);

### anjuta_plugin_manager_get_active_plugins ()

    GList *             anjuta_plugin_manager_get_active_plugins
                                                            (AnjutaPluginManager *plugin_manager);

### anjuta_plugin_manager_get_interface()

    #define             anjuta_plugin_manager_get_interface(plugin_manager, iface_type, error)

Equivalent to `anjuta_plugin_manager_get_object()`, but additionally typecasts returned object to the interface type. It also takes interface type directly. A usage of this function is:

    IAnjutaDocumentManager *docman =
        anjuta_plugin_manager_get_interface (plugin_manager, IAnjutaDocumentManager, error);

`plugin_manager` : | A AnjutaPluginManager object
`iface_type` : | The interface type implemented by the object to be found
`error` : | Error propagation object.

### anjuta_plugin_manager_get_plugin ()

    GObject *           anjuta_plugin_manager_get_plugin    (AnjutaPluginManager *plugin_manager,
                                                             const gchar *iface_name);

Searches the currently available plugins to find the one which implements the given interface as primary interface and returns it. If the plugin is not yet loaded, it will be loaded and activated. It only searches from the pool of plugin objects loaded in this shell and can only search by primary interface. If there are more objects implementing this primary interface, user might be prompted to select one from them (and might give the option to use it as default for future queries). A typical usage of this function is:

    GObject *docman =
        anjuta_plugin_manager_get_plugin (plugin_manager, "IAnjutaDocumentManager", error);

Notice that this function takes the interface name string as string, unlike `anjuta_plugins_get_interface()` which takes the type directly. If no plugin implementing this interface can be found, returns NULL.

`plugin_manager` : | A AnjutaPluginManager object
`iface_name` : | The interface implemented by the object to be found
Returns : | The plugin object (subclass of AnjutaPlugin) which implements the given interface or NULL. See AnjutaPlugin for more detail on interfaces implemented by plugins.

### anjuta_plugin_manager_get_plugin_by_id ()

    GObject *           anjuta_plugin_manager_get_plugin_by_id
                                                            (AnjutaPluginManager *plugin_manager,
                                                             const gchar *plugin_id);

Searches the currently available plugins to find the one with the specified identifier. If the plugin is not yet loaded, it will be loaded and activated.

`plugin_manager` : | A AnjutaPluginManager object
`plugin_id` : | The plugin id
Returns : | The plugin object (subclass of AnjutaPlugin)

### anjuta_plugin_manager_get_plugin_description ()

    AnjutaPluginDescription * anjuta_plugin_manager_get_plugin_description
                                                            (AnjutaPluginManager *plugin_manager,
                                                             GObject *plugin);

### anjuta_plugin_manager_get_plugins_page ()

    GtkWidget *         anjuta_plugin_manager_get_plugins_page
                                                            (AnjutaPluginManager *plugin_manager);

### anjuta_plugin_manager_get_remembered_plugins ()

    gchar *             anjuta_plugin_manager_get_remembered_plugins
                                                            (AnjutaPluginManager *plugin_manager);

Get the list of plugins loaded when there is a choice between several ones without asking the user.

The list format is returned as a string with the format detailed in `anjuta_plugin_manager_set_remembered_plugins()`.

`plugin_manager` : | A AnjutaPluginManager object
Returns : | a newly-allocated string that must be freed with `g_free()`.

### anjuta_plugin_manager_get_remembered_plugins_page ()

    GtkWidget *         anjuta_plugin_manager_get_remembered_plugins_page
                                                            (AnjutaPluginManager *plugin_manager);

### anjuta_plugin_manager_is_active_plugin ()

                                                            (AnjutaPluginManager *plugin_manager,
                                                             const gchar *iface_name);

Set the list of plugins loaded when there is a choice between several ones without asking the user. The list is a string composed of elements separated by ';'. Each element is defined with "key=value", where key is the list of possible plugins and the value is the choosen plugin.

By the example the following element

      anjuta-symbol-browser:SymbolBrowserPlugin,anjuta-symbol-db:SymbolDBPlugin,=anjuta-symbol-db:SymbolDBPlugin;

means if Anjuta has to choose between SymbolBrowserPlugin and SymbolDBPlugin, it will choose SymbolDBPlugin.
