    Problem Text
    The reference implementation (i.e. The Motif code provided by TOG) being

    tested is not in line with the standard specification for this Motif
    function as defined in the "X/Open Motif Toolkit API".
    The assertion being tested is in line with the standard specification
    but the behavior of this function is not in line with the specification.

    Either the Motif reference implementation is at fault, or the
    Specification needs to be aligned with the reference implemenation. It
    is our understanding that Motif 1.2.X is no longer supported by TOG,
    hence we request this waiver be granted a Permanent Interpretation.

    The description of the kill-to-end-of-line() action routine in the
    "X/Open Motif Toolkit API" states the following:

    "In normal mode, if there is a non-null selection, deletes the
    selection;
    otherwise, kills the characters following the insertion cursor to the
    next end of line character and stores the characters in the cut buffer.
    In add mode, if there is a non-null selection, the cursor is not
    disjoint
    from the selection, and XmNpendingDelete is set to True, deletes the
    selection; otherwise, kills the characters following the insertion
    cursor to the next end of line character and stores the characters in
    the cut buffer. This may impact the selection."




    The KillToEndOfLine() function does not check for any of the conditions
    stated above (i.e. non-null selection, add/normal mode, or
    XmNpendingDelete). Instead it always removes the text from the
    insertion cursor to the end of line.

    The reason for the error message above is this. The test suite
    places some text in the widget and then selects the characters
    at positions 0 to 32.

    XmTextSetSelection(Text_info->widget, 0, 32, xisGetServerTime(0) )
    ;

    Next, the test suite positions the cursor at position 44.

    XmTextSetInsertionPosition(Text_info->widget, 44 ) ;

    Then, it invokes the kill-to-end-of-line() action.

    xisClickKey(KeyKillToEOL);

    Since there is a non-null selection the selected text should be deleted.

    This would cause the cursor, which is AFTER the selection, to move to
    the left because the text to its left was deleted. But, since the
    KillToEndOfLine function always deletes from the current cursor position

    to the end of line, the cursor remains where it is. Hence, we get an
    error message because the cursor didn't move.

    static void
    #ifdef _NO_PROTO
    KillToEndOfLine( w, event, params, num_params )
    Widget w ;
    XEvent *event ;
    String *params ;
    Cardinal *num_params ;
    #else
    KillToEndOfLine(
    Widget w,
    XEvent *event,
    String *params,
    Cardinal *num_params )
    #endif /* _NO_PROTO */
    {
    XmTextWidget tw = (XmTextWidget) w;

    (*tw->text.output->DrawInsertionPoint)( tw,
    tw->text.cursor_position, off);
    RemoveToEndOfLine(w, event, params, num_params, TRUE);
    (*tw->text.output->DrawInsertionPoint)( tw,
    tw->text.cursor_position, on);




    }

    The function should be modified to look like this:

    static void
    #ifdef _NO_PROTO
    KillToEndOfLine( w, event, params, num_params )
    Widget w ;
    XEvent *event ;
    String *params ;
    Cardinal *num_params ;
    #else
    KillToEndOfLine(
    Widget w,
    XEvent *event,
    String *params,
    Cardinal *num_params )
    #endif /* _NO_PROTO */
    {
    XmTextPosition left, right;

    XmTextWidget tw = (XmTextWidget) w;

    (*tw->text.output->DrawInsertionPoint)( tw,
    tw->text.cursor_position, off);

    if (NeedsPendingDeleteDisjoint( tw, &left, &right, True))
    DeleteCurrentSelection( w, event, params, num_params);
    else
    RemoveToEndOfLine( w, event, params, num_params, True);

    (*tw->text.output->DrawInsertionPoint)( tw,
    tw->text.cursor_position, on);
    }

    Review Response
    A non-alignment between the reference code and its specification is
    under investigation. Thus it is recommended that a Temporary
    Interpretation be granted for this test while it remains subject to review.
    If a change to the specification results from the conclusion of this
    investigation, then this Temporary Interpretation will be converted
    to a Permanent Waiver. Otherwise this Temporary Interpretation will
    be converted to a Temporary Waiver (Minor System Fault).
