HITTESTHook

TextEdit calls HITTESTHook to determine the character position in a line,

given the pixel width from the left edge of the view rectangle. The default

action is to call the TextWidth function to determine if the pixel width of the

measured text is greater than the input width. If it is, then HITTESTHook

calls the Script Manager's Pixel2Char function and returns. For more

information on Pixel2Char, refer to the

Worldwide Software Overview. For comprehensive details, see

Macintosh Worldwide Development: Guide to System Software.
