Re: VisAD Component "weight"

That sounds like a pretty good idea. I didn't even think of a JTabbedPane. I also have to thank you for the link to, it's a great resource that I didn't know existed.

Thanks again for all your help

Hi Bruce,

Actually, I think it is the other way around with SDI/MDI:
   SDI means one (single) document per frame
   MDI means multiple documents in one master frame

The original idea was that with SDI, you spawned a separate instance of the application for each document, hence "single document interface." So I suppose technically, both the multiple JFrame and single JInternalFrame approaches are "multiple document" approaches, although MDI usually means "all documents in one master frame."

Given the number of windows you need to work with, my suggestion is to use tabs. I know JTabbedPane can be made to work with Java3D (others on the VisAD list have mentioned it in the past). According to's article on Java3D and Swing -- -- JTabbedPane will work "as long as you only put J3D in the |JTabbedPane| and not any Swing elements." But you can easily detect which tab is active and toggle the states of various nearby Swing components to create the same effect.

Good luck,

Hey Curtis,

That's funny, I just got done having a discussion with co-workers debating MDI vs. SDI.

Just for clarity, my understanding is as follows:
SDI: All windows inside a main application window. ie. JDesktopPane with JInternalFrames MDI: As you described, all separate window controlled by a main window controller

The problem with MDI is that we have any number of instruments each with a 6 window display. If you are displaying 3 instruments at once you have 18 windows that look the same except for the title bar with the instrument name. Also, the application is a monitoring application and a MDI does not easily restrict the application to a small piece of screen real-estate.

The other option being considered is a sudo-SDI where each of the 6 components for an instrument would be in a scrollable/slideable panel in a single JFrame. One for each instrument. The problem with this approach is when a user wants to maximize a graph the handling of the scroll/slider panes would be a mess.

So we're juggling around MDI, SDI, or sudo-SDI, to accommodate the large amounts of windows. Any suggestions or comments are more than welcome.

I'm going to tryout the 2D display just to test the feasibility of using the JInternalFrames and see if I can get that working.
