XmTextFieldReplaceWcs replaces part of the wide character string
in the TextField widget. The character positions begin at 0 (zero) and are
numbered sequentially from the beginning of the text.
An example text replacement would be to replace
the second and third characters in the text string. To accomplish this,
the parameter from_pos must be 1 and to_pos must be 3. To
insert a string after the fourth character, both parameters,
from_pos and to_pos, must be 4.
This routine calls the widgets XmNvalueChangedCallback and
verification callbacks, either XmNmodifyVerifyCallback or
XmNmodifyVerifyCallbackWcs, or both. If both verification
callback lists are registered, the procedures of the
XmNmodifyVerifyCallback list are executed first and the resulting
data is passed to the XmNmodifyVerifyCallbackWcs callbacks.
If the XmNcursorPosition resource is greater than or is the same value as
from_pos, the XmNmotionVerifyCallback is called.
