NAMEDtEditorReplaceFromFile — replace a portion of the contents of a DtEdi‐
tor widget with the contents of a file
SYNOPSIS
#include <Dt/Editor.h>
DtEditorErrorCode DtEditorReplaceFromFile(
Widget widget,
XmTextPosition startPos,
XmTextPosition endPos,
char *fileName);
DESCRIPTION
The DtEditorReplaceFromFile function replaces part of the contents of a
DtEditor widget with the contents of a file. All data following the
start position and up to, but not including, the end position is
replaced. If the start position and the end position are equal, the
data is inserted after the end position. The character positions begin
at zero and are numbered sequentially from the beginning of the text.
After the replacement, the insertion cursor is positioned after the
last character inserted.
The widget argument specifies the DtEditor widget ID.
The startPos argument specifies the starting character position of the
portion to replace. The replacement begins at this character.
The endPos argument specifies the ending character position of the por‐
tion to replace. The replacement ends before this character.
The fileName argument is the pathname of the file relative to the local
system.
For a complete definition of the DtEditor widget and its associated
resources, see DtEditor(3).

returns one of the following values:
DtEDITOR_NO_ERRORS
The file is readable and writable.
DtEDITOR_READ_ONLY_FILE
The file is read only.
DtEDITOR_NULLS_REMOVED
