[wxruby-users] GridTableBase

[Mario Steele]

If this is all top level code, you need to initialize the Wx::App class
first.  When I try this, and change the bottom part where you create the new
grid and gridtablebase, it runs alright.

App.new do
  g = Grid.new
  gt = MyGridTablebBase.new
  g.set_table(gt)
end

What platform are you running on?
