Re: VisAD Component "weight"


The plots within each tab (can display either one or four) can be
different sizes depending upon where the user drags the splitPane bar;
that appears to work ok for me as you tab between ones where the drag
bar has been moved.  One of the display options is to "maximize" the
selected plot (of the four), which is accomplished by simply replacing
the 2x2 layout in the JPanel "container" with a single plot and then
appropriately repainting everything.

Two problems which I have which you should be aware of are 1)
potentially flaky OpenGL implementations/settings with the different
graphics cards we use which sometimes cause native code exceptions when
trying to manually resize/move the JFrame.  And 2) sometimes I get
"bleed-through" in the left-hand tabbedPane used for the GUI widgets
depending upon when GUI repaints occur since the plot rendering, which
triggers the GUI widget creation, is done in a separate thread and not
the main one.  While annoying, it goes away with a simple click on the
GUI which forces a repaint.

I like your interface.  Are your plots always the same size and that's 
why the 3D canvas is not a problem in the tabs?  A feature that I would 
like to be implement is the ability to "maximize" a plot.  But, if I 
make a plot take up the whole tab won't it interfere with the other
