## Implemented Interfaces

TpSimpleApprover implements TpSvcDBusProperties, TpSvcClient, TpSvcClientObserver, TpSvcClientApprover, TpSvcClientHandler and TpSvcClientInterfaceRequests.

## Properties

      "callback"                 gpointer              : Write / Construct Only
      "destroy"                  gpointer              : Write / Construct Only

## Description

This class makes it easier to construct a TpSvcClient implementing the TpSvcClientApprover interface.

A typical simple approver would look liks this:

    static void
    my_add_dispatch_operation (TpSimpleApprover *approver,
       TpAccount *account,
       TpConnection *connection,
       GList *channels,
       TpChannelDispatchOperation *dispatch_operation,
       TpAddDispatchOperationContext *context,
       gpointer user_data)
    {
     /* call tp_channel_dispatch_operation_handle_with_async()
     if wanting to approve the channels */

     tp_add_dispatch_operation_context_accept (context);
    }

    factory = tp_automatic_client_factory_new (dbus);
    client = tp_simple_approver_new_with_factory (factory, "MyApprover", FALSE,
       my_add_dispatch_operation, user_data);
    g_object_unref (factory);

    tp_base_client_take_approver_filter (client, tp_asv_new (
         TP_PROP_CHANNEL_CHANNEL_TYPE, G_TYPE_STRING, TP_IFACE_CHANNEL_TYPE_TEXT,
         TP_PROP_CHANNEL_TARGET_HANDLE_TYPE, G_TYPE_UINT, TP_HANDLE_TYPE_CONTACT,
         NULL));

    tp_base_client_register (client, NULL);

See examples/client/text-approver.c for a complete example.

Signature of the implementation of the AddDispatchOperation method.

This function must call either `tp_add_dispatch_operation_context_accept()`, `tp_add_dispatch_operation_context_delay()` or `tp_add_dispatch_operation_context_fail()` on `context` before it returns.

`approver` : | a TpSimpleApprover instance
`account` : | a TpAccount having `TP_ACCOUNT_FEATURE_CORE` prepared if possible
`connection` : | a TpConnection having `TP_CONNECTION_FEATURE_CORE` prepared if possible
`channels` : | a GList of TpChannel, all having `TP_CHANNEL_FEATURE_CORE` prepared. [element-type TelepathyGLib.Channel]
`dispatch_operation` : | a TpChannelDispatchOperation or `NULL`; the dispatch_operation is not guaranteed to be prepared. [allow-none]
`context` : | a TpAddDispatchOperationContext representing the context of this D-Bus call
`user_data` : | arbitrary user-supplied data passed to `tp_simple_approver_new()`

Since 0.11.5

### tp_simple_approver_new ()

    TpBaseClient *      tp_simple_approver_new              (TpDBusDaemon *dbus,
                                                             const gchar *name,
                                                             gboolean uniquify,
                                                             TpSimpleApproverAddDispatchOperationImpl callback,
                                                             gpointer user_data,

### Warning

`tp_simple_approver_new` is deprecated and should not be used in newly-written code. New code should use `tp_simple_approver_new_with_am()` instead.

Convenient function to create a new TpSimpleApprover instance.

If `dbus` is not the result of `tp_dbus_daemon_dup()`, you should call `tp_simple_approver_new_with_am()` instead, so that TpAccount, TpConnection and TpContact instances can be shared between modules.

`dbus` : | a TpDBusDaemon object, may not be `NULL`
`name` : | the name of the Approver (see "name" for details)
`uniquify` : | the value of the "uniquify-name" property
`callback` : | the function called when AddDispatchOperation is called
`user_data` : | arbitrary user-supplied data passed to `callback`
`destroy` : | called with `user_data` as its argument when the TpSimpleApprover is destroyed
Returns : | a new TpSimpleApprover. [type TelepathyGLib.SimpleApprover]

Since 0.11.5

### tp_simple_approver_new_with_am ()

    TpBaseClient *      tp_simple_approver_new_with_am      (TpAccountManager *account_manager,
                                                             const gchar *name,
                                                             gboolean uniquify,
                                                             TpSimpleApproverAddDispatchOperationImpl callback,

Convenient function to create a new TpSimpleApprover instance with a specified TpAccountManager.

It is not necessary to prepare any features on `account_manager` before calling this function.

`account_manager` : | an account manager, which may not be `NULL`
`name` : | the name of the Approver (see "name" for details)
`uniquify` : | the value of the "uniquify-name" property
`callback` : | the function called when AddDispatchOperation is called
`user_data` : | arbitrary user-supplied data passed to `callback`
