Functions

@JvmName(name = "bind")
fun MessageListHeaderViewModel.bindView(view: MessageListHeaderView, lifecycle: LifecycleOwner)

Binds MessageListHeaderView with MessageListHeaderViewModel, updating the view's state based on data provided by the ViewModel.

@JvmName(name = "bind")
fun MessageListViewModel.bindView(view: MessageListView, lifecycleOwner: LifecycleOwner)

Binds MessageListView with MessageListViewModel, updating the view's state based on data provided by the ViewModel, and forwarding View events to the ViewModel.

@JvmName(name = "bind")
@JvmOverloads
fun MessageComposerViewModel.bindView(view: MessageComposerView, lifecycleOwner: LifecycleOwner, messageBuilder: () -> Message = { buildNewMessage() }, sendMessageButtonClickListener: (Message) -> Unit = this.sendMessageButtonClickListener, textInputChangeListener: (String) -> Unit = this.textInputChangeListener, attachmentSelectionListener: (List<Attachment>) -> Unit = this.attachmentSelectionListener, attachmentRemovalListener: (Attachment) -> Unit = this.attachmentRemovalListener, mentionSelectionListener: (User) -> Unit = this.mentionSelectionListener, commandSelectionListener: (Command) -> Unit = this.commandSelectionListener, alsoSendToChannelSelectionListener: (Boolean) -> Unit = this.alsoSendToChannelSelectionListener, dismissActionClickListener: () -> Unit = this.dismissActionClickListener, commandsButtonClickListener: () -> Unit = this.commandsButtonClickListener, dismissSuggestionsListener: () -> Unit = this.dismissSuggestionsListener, audioRecordButtonHoldListener: () -> Unit = this.audioRecordButtonHoldListener, audioRecordButtonLockListener: () -> Unit = this.audioRecordButtonLockListener, audioRecordButtonCancelListener: () -> Unit = this.audioRecordButtonCancelListener, audioRecordButtonReleaseListener: () -> Unit = this.audioRecordButtonReleaseListener, audioDeleteButtonClickListener: () -> Unit = this.audioDeleteButtonClickListener, audioStopButtonClickListener: () -> Unit = this.audioStopButtonClickListener, audioPlaybackButtonClickListener: () -> Unit = this.audioPlaybackButtonClickListener, audioCompleteButtonClickListener: () -> Unit = this.audioCompleteButtonClickListener, audioSliderDragStartListener: (Float) -> Unit = this.audioSliderDragStartListener, audioSliderDragStopListener: (Float) -> Unit = this.audioSliderDragStopListener)

Function which connects MessageComposerView to MessageComposerViewModel. As a result the view renders the state delivered by the ViewModel, and the ViewModel intercepts the user's actions automatically.

@JvmName(name = "bindDefaults")
@JvmOverloads
fun MessageComposerViewModel.bindViewDefaults(view: MessageComposerView, lifecycleOwner: LifecycleOwner, messageBuilder: () -> Message = { buildNewMessage() }, sendMessageButtonClickListener: (Message) -> Unit? = null, textInputChangeListener: (String) -> Unit? = null, attachmentSelectionListener: (List<Attachment>) -> Unit? = null, attachmentRemovalListener: (Attachment) -> Unit? = null, mentionSelectionListener: (User) -> Unit? = null, commandSelectionListener: (Command) -> Unit? = null, alsoSendToChannelSelectionListener: (Boolean) -> Unit? = null, dismissActionClickListener: () -> Unit? = null, commandsButtonClickListener: () -> Unit? = null, dismissSuggestionsListener: () -> Unit? = null, audioRecordButtonHoldListener: () -> Unit? = null, audioRecordButtonLockListener: () -> Unit? = null, audioRecordButtonCancelListener: () -> Unit? = null, audioRecordButtonReleaseListener: () -> Unit? = null, audioDeleteButtonClickListener: () -> Unit? = null, audioStopButtonClickListener: () -> Unit? = null, audioPlaybackButtonClickListener: () -> Unit? = null, audioCompleteButtonClickListener: () -> Unit? = null, audioSliderDragStartListener: (Float) -> Unit? = null, audioSliderDragStopListener: (Float) -> Unit? = null)

Function which connects MessageComposerView to MessageComposerViewModel. As a result the view renders the state delivered by the ViewModel, and the ViewModel intercepts the user's actions automatically. The main difference with bindView is that listeners in this function do not override the default behaviour.
