Provided Methods

fn textField_textView_candidatesForSelectedRange( &self, text_field: &NSTextField, text_view: &NSTextView, selected_range: NSRange, ) -> Option<Retained<NSArray>>

where Self: Sized + Message,

Available on crate features NSResponder and NSText and NSTextView and NSView only.

Provides a customized list of candidates to the text view’s candidateListTouchBarItem. Invoked from -updateCandidates. NSTextView uses the candidates returned from this method and suppress its built-in candidate generation. Returning nil from this delegate method allows NSTextView to query candidates from NSSpellChecker.

• Returns: An array of objects that represent the elements of a selection.

fn textField_textView_candidates_forSelectedRange( &self, text_field: &NSTextField, text_view: &NSTextView, candidates: &NSArray<NSTextCheckingResult>, selected_range: NSRange, ) -> Retained<NSArray<NSTextCheckingResult>>

where Self: Sized + Message,

Available on crate features NSResponder and NSText and NSTextView and NSView only.

Allows customizing the candidate list queried from NSSpellChecker.

• Returns: An array of text objects to include in a text selection.

fn textField_textView_shouldSelectCandidateAtIndex( &self, text_field: &NSTextField, text_view: &NSTextView, index: NSUInteger, ) -> bool

where Self: Sized + Message,

Available on crate features NSResponder and NSText and NSTextView and NSView only.

Notifies the delegate that the user selected the candidate at index in -[NSCandidateListTouchBarItem candidates] for the text view’s candidateListTouchBarItem. Returns a Boolean value that indicates whether to select the text object at the index.

• Parameters:
• textField: The text field that sent the message.
• textView: The text view that sent the message.
• index: The index that represents the start of the candidate text to evaluate, or NSNotFound if no candidate is to be selected.
• Returns: YES if the framework selects the text. YES allows textView to insert the candidate into the text storage if it’s NSString, NSAttributedString, or NSTextCheckingResult.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
