FindWord

Locate a position in a string

#include <Script.h> Script Manager

void FindWord(textPtr, textLength, offset, leadingEdge, breaks,

offsets );

Ptr textPtr ; address of a text string

short textLength ; value for text length

short offset ; value for a position in the text string

Boolean leadingEdge ; use if pixel width falls within character's left side

BreakTablePtr breaks ; list of word-division templates

OffsetTable offsets ; value indicating string position

FindWord takes a text string, and a position in the string, and returns

offsets specifying the word's boundaries.

textPtr is a text string indicated by a pointer.

textLength is the length of the specified string.

offset is a position in the text string.

leftSide is a Boolean flag that is set if the pixel width falls within the left

side of a character. It can be used for word selection and for

positioning the cursor correctly at the end of lines.

breaks is a list of templates that help determine the boundaries of a word.

If breaks is Nil, the default word-selection break table for the

current script is used. If it is Ptr(-1L), the default word-wrapping

break table is used. If breaks has another value, it should point to a

valid break table that will become the default.

offsets indicates the boundaries (beginning and end) of the selected word.

Notes: Word-selection break tables give a words boundaries when you want to

select or drag them, or for such utilities as spell checking. Wrapping break

tables are used to distinguish words for finding the widths of lines for

wrapping.
