XmTextReplace replaces part of the text string in the Text 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.
The XmNmotionVerifyCallback is generated if to_pos is less
than or equal to
the cursor position and the length of value is not the same as the
length of the text being replaced, or if the cursor position is between
from_pos and to_pos, and the distance from the cursor
position to from_pos is greater than the length of value.
