PURPOSE:

This is a SMALL start-up program for prog0 using fltk. I have
referenced some code from Eric Schmitt, Krishna Roskin, Doanna
Weissgerber.
	
GETTING STARTED: 

Copy this entire directory into your own workspace. (Again, it's
small)

The prog0 start-up program has sliders, buttons, a menu with menu
options, and a browser. The program is designed to load-in and rotate
the enterprise. The enterprise is not loaded until the load button is
hit and a file is selected.

	
gui.cxx and gui.h: are generated files using fluid. Fluid is the
similar to fdesign for forms. Make sure fluid is in your path
(/usr/local/bin). To modify you interface type
fluid gui.fl

RUNNING THE STARTUP:

Load Button: 
- brings up a browser to choose a file 
- if a file is chosen calls the load() function (note: currently the
enterprise coor and poly files are hard coded and will load up
regardless of file selection.)
	   
Quit Button: 
- causes the quit_cb() to be invoked
	
CGL_Window: 
- gl_window overloaded from the Fl_Gl_Window 
- do your GL drawing here in drawPicture().
- you may also want to carefully check out draw()
	
Menu: 
- quit_file_menu_item: prints the string to show you the label of the
menuitem then get same function as quit button
	
Sliders:
- x, y, and z invoke rotatex(), rotatey(), and rotatez() 
defined in gl_window.h
-zoom invoke zoom() defined in gl_window.h

Have fun,
