Hi All,
I have a thread in eclipse.tools asking if eclipse is right for my task, I
am expanding that to see if GEF would be right for the graphical part if it.
Imagine a grid of very small boxes, each big enough to hold a singel symbol
the size of a normal charachter. The grid could easily be >1000x>1000.
Each location can hold either blank space or a single colored charachter.
Point in click, select the character and click a location and it paints it
in. Simple enough?
Finally, I would need to print this possibly scaling it to fit a page,
multiple pages, etc.
So I guess the question is, is there something in GEF that will make this
faster/easier than just implimenting it myself with normal SWT components?
Thanks,
Jake T.

draw2d has double buffered painting and zoom support. Other than that, I
would suggest that you paint the grid yourself due to the number of cells.
You could implement your grid as some type of figure, and put it in a figure
canvas.

Thanks,
I'm kind of worried too, I can't really think of a better way, at least for
now.... I am a J2EE developer and almost never deal with GUIs. So, this
will be a heck of a learning experience.

theoretically yes. But you won't find a monitor that displays them all.
So you could quite easyly have some mapper in between from model to display.
