This is an object graphics view, right? It depends on how the view UNITS and
DIMENSIONS are specified. If UNITS has the value 0 (pixels), 1 (inches) or 2
(centimetres) *and* the DIMENSIONS are non-zero then the view size will
remain constant as the destination device (in this case draw widget) is
resized. If UNITS has the value 3 (relative to window) *or* DIMENSIONS are
zero, then the view will fit itself to the destination.
An IDLgrView defaults to UNITS=0 and DiMENSIONS=[0,0] (I think) but I almost
always use UNITS=2 and non-zero DIMENSIONS (10-12 cm is often about right).
This way I get hard copy output the same size (in centimetres) as what I see
on the screen. I have code that ensures the draw widget always fit tightly
around the view.
