Package: sciplot-dev
Version: 1.36-8   

Some old sciplot-using code of mine compiles without warning but says

> Error: attempt to add non-widget child "DropSiteManager" to parent
> "plotonline" which supports only widgets

when I compile it using a modern sciplot.

The error seems to occur within the last statement in this sequence:

  toplevel = XtAppInitialize(&app_con, "SciPlot",
			     NULL, 0, &argc, argv, NULL, NULL,
			     0);
  dummy =
    XtVaCreateManagedWidget("dummy",
			    /* sciplotWidgetClass, toplevel, */
			    coreWidgetClass, toplevel,

			    XtNchartType, (polar_plot
					   ? XtPOLAR
					   : XtCARTESIAN),
			    XtNdegrees, True,
			    XtNwidth, 1,
			    XtNheight, 1,
			    XtNplotTitle, title,
			    XtNxLabel, xlabel,
			    XtNyLabel, ylabel,
			    XtNshowLegend, False,
			    XtNxLog, xlog,
			    XtNyLog, ylog,

			    XtNdrawMajor, False,
			    XtNdrawMinor, False,

			    NULL);

  XtSetMappedWhenManaged(toplevel, False);

  plot = SciPlotDialog(toplevel, title);

If the same source is compiled on potato, with sciplot 1.36-3, it runs
fine.  The resulting executable runs fine even on a frozen machine
with 1.36-8.


Also ... the example /usr/doc/sciplot-dev/examples/xyplot.c fails to
compile, because it cannot seem to

    #include <Xm/PushB.h>
    #include <Xm/MainW.h>

Please don't take ... my sciplot ... away.
