request_contact_info_async
Description:
public async bool request_contact_info_async (Cancellable? cancellable) throws Error
Requests an asynchronous request of the contact info of this.
When the operation is finished, callback will be called. You can then call request_contact_info_async.end
to get the result of the operation.
If the operation is successful, the contact_info
property will be updated (emitting "notify::contact-info" signal) before callback is called. That means you can call
get_contact_info to get the new vCard inside
callback.
Note that requesting the vCard from the network can take significant time, so a bigger timeout is set on the underlying D-Bus call.
cancellable can be cancelled to free resources used in the D-Bus call if the caller is no longer interested in the vCard.
If CONTACT_INFO is not yet set on
this, it will be set before its property gets updated and callback is called.
Parameters:
| this |
a Contact |
| cancellable |
optional Cancellable object, |
| callback |
a callback to call when the request is satisfied |
| user_data |
data to pass to |
