Provided Methods

unsafe 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.

unsafe 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.

unsafe 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.
