Provided Methods

unsafe fn shouldDeferEventHandlingToSystemForTextInput_context( &self, text_input: &ProtocolObject<dyn BETextInput>, key_event_context: &BEKeyEntryContext, ) -> bool

where Self: Sized + Message,

Available on crate features BEKeyEntryContext and BETextInput only.

Defers the key event to the system and returns whether the key event was handled.

For example, the system will handle key events for character insertions, deletions, key commands, and more.

unsafe fn textInput_setCandidateSuggestions( &self, text_input: &ProtocolObject<dyn BETextInput>, suggestions: Option<&NSArray<BETextSuggestion>>, )

where Self: Sized + Message,

Available on crate features BETextInput and BETextSuggestion only.

Provides text suggestions to the system.

For example, suggestions could include data list elements or AutoFill candidates.

unsafe fn selectionWillChangeForTextInput( &self, text_input: &ProtocolObject<dyn BETextInput>, )

where Self: Sized + Message,

Available on crate feature BETextInput only.

Tells the system when the selection is about to change in the document.

unsafe fn selectionDidChangeForTextInput( &self, text_input: &ProtocolObject<dyn BETextInput>, )

where Self: Sized + Message,

Available on crate feature BETextInput only.

Tells the system when the selection has changed in the document.

This method results in an document state refresh with an invocation to: -[BETextInput requestTextContextForAutocorrectionWithCompletionHandler:]

unsafe fn textInput_deferReplaceTextActionToSystem( &self, text_input: &ProtocolObject<dyn BETextInput>, sender: &AnyObject, )

where Self: Sized + Message,

Available on crate feature BETextInput only.

Defers a replace text action to the ssytem.

When handling the replace: action, use this method to defer the replacement to the system.

For example, a replacement could be deferred after it is selected from the autocorrect replacements list.

unsafe fn invalidateTextEntryContextForTextInput( &self, text_input: &ProtocolObject<dyn BETextInput>, )

where Self: Sized + Message,

Available on crate feature BETextInput only.

Tells the system the text entry context has changed and that text entry UI’s need to be refreshed.

This is a costly operation and should only used with intention. For example, when switching focus between different elements.
