)

Public Overridable Function TextViewShouldChangeTextInRangesReplacementStrings ( _
	textView As NSTextView, _
	affectedRanges As NSArray, _
	replacementStrings As NSArray _
) As Boolean

public:
virtual bool TextViewShouldChangeTextInRangesReplacementStrings(
	NSTextView^ textView, 
	NSArray^ affectedRanges, 
	NSArray^ replacementStrings
)

Parameters

textView (NSTextView): The text view sending the message. This is the first text view in a series shared by a layout manager, not necessarily the text view displaying the selected text.

affectedRanges (NSArray): The array of ranges of characters to be replaced. This array must be a non-nil, non-empty array of objects responding to the NSValue rangeValue method, and in addition its elements must be sorted, non-overlapping, non-contiguous, and (except for the case of a single range) have non-zero-length.

replacementStrings (NSArray): The array of strings that will replace the characters in affectedRanges, one string for each range; nil if only text attributes are being changed.

Return Value

YES to allow the replacement, or NO to reject the change.
