gtk_plot_canvas_child_move_resize() on a line?

	I have put two children on a GtkPlotCanvas, one is an ellipse and the
other a line:

--------------------

  /* Create the bubble, start it at center screen so we don't get any
     trouble being off-canvas. */
  plotBubbleEllipse =
    gtk_plot_canvas_ellipse_new(GTK_PLOT_LINE_SOLID,
				1,
				(GdkColor *)NULL,
				(GdkColor *)NULL,
				FALSE);

  gtk_plot_canvas_put_child(GTK_PLOT_CANVAS(canvas),
			    plotBubbleEllipse,
			    0.5 - BUBBLE_CENTER_OFFSET_X,
			    0.5 - BUBBLE_CENTER_OFFSET_Y,
			    0.5 + BUBBLE_CENTER_OFFSET_X,
			    0.5 + BUBBLE_CENTER_OFFSET_Y);

  /* Create the line. */
  plotBubbleLine = 
    gtk_plot_canvas_line_new(GTK_PLOT_LINE_SOLID,
			     1,
			     (GdkColor *)NULL,
			     GTK_PLOT_CANVAS_ARROW_NONE);

  gtk_plot_canvas_put_child(GTK_PLOT_CANVAS(canvas),
			    plotBubbleLine,
			    0.5,
			    0.5 + BUBBLE_CENTER_OFFSET_Y,
			    0.5,
			    0.7);

--------------------



	I then attempt to move both of them:

gtk_plot_canvas_child_move(GTK_PLOT_CANVAS(canvas),
			     GTK_PLOT_CANVAS_CHILD(plotBubbleEllipse),
			     bubbleX - BUBBLE_CENTER_OFFSET_X,
			     bubbleY + BUBBLE_CENTER_OFFSET_Y);

  gtk_plot_canvas_child_move_resize(GTK_PLOT_CANVAS(canvas),
GTK_PLOT_CANVAS_CHILD(plotBubbleLine),
				    lineX,
				    lineY,
				    runX[countRunPoints],
				    runY[countRunPoints]);
    


	I have confirmed that my coordinate values above are correct (lineX,
lineY, etc.).  However, the ellipse moves, but the line does not.  The
line just stays where I initially put it.


	Adrian: is it not possible to move/resize a line that is a child in a
canvas, as you can with other kinds of children?


	Thanks!
