Hi,
I am trying to develop some modules in the explorer and have these 2 questions:
(1) I have opended a Gl-Motif window and I want to divide it into 4 equal parts
    to show 4 different views (Perspective, Top, Front, Side) of an object.
    I am drawing the object using gl but my problem is dividing the window so
    that in each a different view can be shown.
(2) I want to build up a dialog box similar to the Connections window that pops up
    in the module builder. Specifically, on two sides of my window various buttons 
    would be shown. The user can connect a button from 1 side to a button in the 
    other side. Once connected, the connection would be shown by a blue line (as
    is the case for all connections in Explorer). What is the easiest way to write
    this code?

Hope someone can help!

   I'd take a look at the viewport() command.  It controls where you're 
graphics are going to be drawn in the window.

    Given that you probably have only GL and X/Motif to choose from, its got
to be one of them.  Buttons and popups like Explorer uses are a result of
Motif, so that would be the easiest for that.  Since you can't mix X and
GL in a window, if you choose that route, then you'd need to draw the wire
using Xlib.  Its my guess that's how Explorer renders the wires and the like.

Hope that helps.
