/** Some helpers for converting model strings to view strings.
|
|
|
|
A paragraph string does not have its fields expanded, i.e., they are
|
|
represented by a special character inside the string with an additional
|
|
attribute assigned to it. For some tasks (e.g., SmartTags) it is required
|
|
to expand the fields to get the string as it appears in the view. Two
|
|
helper functions are provided to convert model positions to view positions
|
|
and vice versa.
|
|
|
|
CH_TXTATR_BREAKWORD -> SwTxtNode will have field attributes associated with these

|
