    Problem Text

    This is the fault of test case. The test purpose or assertion itself
    is wrong. If we pass in a NULL value for horizontal ,vertical scrollbar or
    work_region, the system does change the corresponding widget to be NULL.
    ^^^^
    The Motif Reference Manual for OSF/Motif Release 1.2 ONLY says: for
    ^^^^
    horizontal_scrollbar, vertical_scrollbar, work_region widgets, "If a particular
    ScrolledWindow does not have one of these regions, the corresponding argument
    can be specified as NULL".

    It will be very clear if you look at the source code for
    XmScrolledWindowSetAreas which is defined in ScrolledW.c of Xm lib. Here is
    the code to set up horizontal_scrollbar and so on:
    if (sw->swindow.WorkWindow != wregion)
    {
    ..............................
    sw->swindow.WorkWindow = wregion;
    /* set the work_region widget to be the value passed in */
    }
    ..............................
    sw->swindow.hScrollBar = (XmScrollBarWidget) hscroll;
    sw->swindow.vScrollBar = (XmScrollBarWidget) vscroll;
    /* set the horizontal_scrollbar and vertical_scrollbar
    to be the values passed in */

    Also There is a problem in msg_failure() func. If we pass in a NULL
    widget ID for horizontal_scrollbar, vertical_scrollbar or work_region widget,
    the "child_window" ID in the test1A, test2A or test3A should be 0, and you
    can use such code to check after the msg_failure() which fails:
    printf("child_window ID is %d 0, child_window);
    but msg_failure() function print out some magic number.

    Review Recommendation No Resolution Given
    Review Response
    We recommend this request be refused.

    The NULL values passed to XmScrolledWindowSetAreas for




    horizontal_scrollbar, vertical_scrollbar and work_region indicate the
    caller does not wish to alter the corresponding area of the
    ScrolledWindow widget.

    On the implementation under test the call to XmScrolledWindowSetAreas
    when passed a NULL for any of the three areas places the value NULL
    for the corresponding resource.

    As per the X/Open specification the XmScrolledWIndowSetAreas call
    cannot be used to set NULL values for the three areas. The
    XmScrolledWindowSetAreas description states:

    Each widget is optional and may be passed as NULL.

    Setting the resource value to NULL can be achieved by setting the
    resource value directly using XtSetValues.

    The error in msg_failure output will be fixed in the next release.
