Functions

expect open fun addCloseable(closeable: AutoCloseable)

expect fun addCloseable(key: String, closeable: AutoCloseable)

clearDraftMessage

fun clearDraftMessage()

clearUnreadCount

fun clearUnreadCount(contact: String, messageUuid: Long, lastReadTimestamp: Long): Job

fun closeSearch()

confirmTranslationModelDownload

fun confirmTranslationModelDownload()

fun deleteMessages(uuidList: List<Long>): Job

dismissTranslationDialog

fun dismissTranslationDialog()

expect fun <T : AutoCloseable> getCloseable(key: String): T?

getMessagesFlow

fun getMessagesFlow(contactKey: String, limit: Int? = null): Flow<List<Message>>

Returns a non-paged reactive Flow of messages for a conversation. Used by desktop targets that don't use paging-compose.

getMessagesFromPaged

fun getMessagesFromPaged(contactKey: String): Flow<PagingData<Message>>

fun getNode(userId: String?): Node

fun getUser(userId: String?): User

navigateToNextResult

fun navigateToNextResult()

navigateToPreviousResult

fun navigateToPreviousResult()

fun sendMessage(str: String, contactKey: String = "0", replyId: Int? = null)

Sends a message to a contact or channel.

fun sendReaction(emoji: String, replyId: Int, contactKey: String): Job

setContactFilteringDisabled

fun setContactFilteringDisabled(contactKey: String, disabled: Boolean)

fun setContactKey(contactKey: String)

setDraftMessage

fun setDraftMessage(text: String)

Updates the in-memory draft immediately. The durable SavedStateHandle write is debounced by DRAFT_PERSISTENCE_DELAY_MS — rapid edits cancel the prior pending flush, so only the trailing value persists. On process death within the debounce window the last ≤DRAFT_PERSISTENCE_DELAY_MS of typing is not durably saved; this is a conscious trade-off to avoid per-keystroke jank.

fun setSearchQuery(query: String)

fun setTitle(title: String)

fun toggleSearch()

toggleShowFiltered

fun toggleShowFiltered()

toggleShowQuickChat

fun toggleShowQuickChat()

toggleShowTranslated

fun toggleShowTranslated(message: Message): Job

translateMessage

fun translateMessage(message: Message): Job

Translates message into the device language, or just re-shows a previously persisted translation.
