Dear All,

how can one extract the actual size of a resizable dynamic object?
The following approach does not work: try to resize the object using
the resize-widget at the lower-right corner.

plot = Plot[Sin[x], {x, 0, 5}, ImageSize -> {300, 200}];
obj = Pane[plot, AppearanceElements -> "ResizeArea"]
Dynamic@CurrentValue[obj, ImageSize]
