Event payload.

Variants

Info(String)

The library-user may write an informational string to the log.

This event should not be reported to the end-user using a popup or something like that.

SmtpConnected(String)

Emitted when SMTP connection is established and login was successful.

ImapConnected(String)

Emitted when IMAP connection is established and login was successful.

SmtpMessageSent(String)

Emitted when a message was successfully sent to the SMTP server.

ImapMessageDeleted(String)

Emitted when an IMAP message has been marked as deleted

ImapMessageMoved(String)

Emitted when an IMAP message has been moved

ImapInboxIdle

Emitted before going into IDLE on the Inbox folder.

NewBlobFile(String)

Emitted when an new file in the $BLOBDIR was created

DeletedBlobFile(String)

Emitted when an file in the $BLOBDIR was deleted

Warning(String)

The library-user should write a warning string to the log.

This event should not be reported to the end-user using a popup or something like that.

Error(String)

The library-user should report an error to the end-user.

As most things are asynchronous, things may go wrong at any time and the user should not be disturbed by a dialog or so. Instead, use a bubble or so.

However, for ongoing processes (eg. configure()) or for functions that are expected to fail (eg. dc_continue_key_transfer()) it might be better to delay showing these events until the function has really failed (returned false). It should be sufficient to report only the last error in a messasge box then.

ErrorSelfNotInGroup(String)

An action cannot be performed because the user is not in the group. Reported eg. after a call to dc_set_chat_name(), dc_set_chat_profile_image(), dc_add_contact_to_chat(), dc_remove_contact_from_chat(), dc_send_text_msg() or another sending function.

MsgsChanged

Messages or chats changed. One or more messages or chats changed for various reasons in the database:

• Messages sent, received or removed
• Chats created, deleted or archived
• A draft has been set

Fields

chat_id: ChatId

Set if only a single chat is affected by the changes, otherwise 0.

Fields

contact_id: ContactId

ID of the contact whose reaction set is changed.

msg_id: MsgId

ID of the message for which reactions were changed.

reaction: Reaction

The reaction.

IncomingMsg

There is a fresh message. Typically, the user will show an notification when receiving this message.

There is no extra #DC_EVENT_MSGS_CHANGED event send together with this event.

Fields

chat_id: ChatId

ID of the chat where the message is assigned.

msg_id: MsgId

ID of the message.

IncomingMsgBunch

Downloading a bunch of messages just finished.

MsgsNoticed(ChatId)

Fields

chat_id: ChatId

ID of the chat which the message belongs to.

msg_id: MsgId

ID of the message that was successfully sent.

MsgFailed

A single message could not be sent. State changed from DC_STATE_OUT_PENDING or DC_STATE_OUT_DELIVERED to DC_STATE_OUT_FAILED, see dc_msg_get_state().

Fields

chat_id: ChatId

ID of the chat which the message belongs to.

msg_id: MsgId

ID of the message that could not be sent.

MsgRead

Fields

chat_id: ChatId

ID of the chat which the message belongs to.

msg_id: MsgId

ID of the message that was read.

MsgDeleted

A single message was deleted.

This event means that the message will no longer appear in the messagelist. UI should remove the message from the messagelist in response to this event if the message is currently displayed.

The message may have been explicitly deleted by the user or expired. Internally the message may have been removed from the database, moved to the trash chat or hidden.

This event does not indicate the message deletion from the server.

Fields

chat_id: ChatId

ID of the chat where the message was prior to deletion. Never 0 or trash chat.

msg_id: MsgId

ID of the deleted message. Never 0.

ChatModified(ChatId)

Chat changed. The name or the image of a chat group was changed or members were added or removed. Or the verify state of a chat has changed. See dc_set_chat_name(), dc_set_chat_profile_image(), dc_add_contact_to_chat() and dc_remove_contact_from_chat().

This event does not include ephemeral timer modification, which is a separate event.

ChatEphemeralTimerModified

Chat ephemeral timer changed.

Fields

chat_id: ChatId

Chat ID.

timer: Timer

New ephemeral timer value.

ContactsChanged(Option<ContactId>)

Contact(s) created, renamed, blocked, deleted or changed their “recently seen” status.

@param data1 (int) If set, this is the contact_id of an added contact that should be selected.

LocationChanged(Option<ContactId>)

Location of one or more contact has changed.

@param data1 (u32) contact_id of the contact for which the location has changed. If the locations of several contacts have been changed, eg. after calling dc_delete_all_locations(), this parameter is set to None.

ConfigureProgress

Inform about the configuration progress started by configure().

Fields

progress: usize

Progress.

0=error, 1-999=progress in permille, 1000=success and done

comment: Option<String>

Inform about the import/export progress started by imex().

@param data1 (usize) 0=error, 1-999=progress in permille, 1000=success and done @param data2 0

ImexFileWritten(PathBuf)

A file has been exported. A file has been written by imex(). This event may be sent multiple times by a single call to imex().

A typical purpose for a handler of this event may be to make the file public to some system services.

@param data2 0

SecurejoinInviterProgress

Progress information of a secure-join handshake from the view of the inviter (Alice, the person who shows the QR code).

These events are typically sent after a joiner has scanned the QR code generated by dc_get_securejoin_qr().

Fields

contact_id: ContactId

ID of the contact that wants to join.

progress: usize

Progress as: 300=vg-/vc-request received, typically shown as “bob@addr joins”. 600=vg-/vc-request-with-auth received, vg-member-added/vc-contact-confirm sent, typically shown as “bob@addr verified”. 800=contact added to chat, shown as “bob@addr securely joined GROUP”.

Fields

contact_id: ContactId

ID of the inviting contact.

progress: usize

Progress as: 400=vg-/vc-request-with-auth sent, typically shown as “alice@addr verified, introducing myself.” (Bob has verified alice and waits until Alice does the same for him) 1000=vg-member-added/vc-contact-confirm received
