The problem is that at the time you''re calling fitColumnsToContents(),
the fonts haven''t been created yet. I can''t seem to get to the
FOX
home page at the moment, but if I could, I''d point you to an item in
the FAQ there that talks about this issue of created versus non-
created fonts (or icons, etc.) There''s also some discussion of it in
section 7.7 of the book, where I talk about client-side versus server-
side objects.
If you just move those two calls to your create() method, e.g.
def create
super
@table.fitColumnsToContents(0,2)
@table.fitRowsToContents(0,2)
show(PLACEMENT_SCREEN)
end
You should get the desired result.
Hope this helps,
Lyle
