Re: bug... GraphicsGrid ItemAspectRatio Spacings

Show all headers | View raw

It looks like Spacings has to be set to some value(s) given in typesetters
"points" (1/72 of an inch), if we want to set ItemAspectRatio to a list.

GraphicsGrid[
 {
  {
   "Z-coordinate",
   "Radius"
   },
  {
   Slider[Dynamic[h], {-2, 2, 0.25}, Appearance -> "Labeled"],
   Slider[Dynamic[r], {0, 1, 0.25}, Appearance -> "Labeled"]
   },
  {
   Graphics[
    Locator[Dynamic[s]],
    PlotRange -> 2,
    Frame -> True,
    Axes -> True
    ],
   Dynamic[
    Graphics3D[
     Sphere[{s[[1]], s[[2]], h}, r],
     PlotRange -> 2,
     Axes -> True,
     AxesLabel -> {"x", "y", "z"}
     ]
    ]
   }
  },
 ItemAspectRatio -> {0.05, 0.05, 1},
 Dividers -> {All, {True, False, True, True}},
 Spacings -> {100, 10}
 ]
