GetWordRange

protoTXView:GetWordRange(offset)

Finds the first and last characters of a word.

offset

The offset from the beginning of the text in the word-processing view.

return value

A range frame that specifies the starting and ending offsets of the word that follows the specified offset in a word-processing view. The *GetWordRange method returns a range frame, as described in "The Range Frame". The *GetWordRange method returns nil if it does not find a word after offset.

DISCUSSION

The *GetWordRange method searches forward in the text to discover the first character and last character of the word that follows offset. This method considers a word to consist of alphanumeric characters delimited by white space (tabs, returns, spaces, and graphic runs). Hyphenated words are considered single words.
