Hm, 'super()' call raises error in NewPanel#initalize, while in 
MainFrame#initialize it works perfectly.

c:/ruby/lib/ruby/gems/1.8/gems/wxruby-1.9.7-i386-mswin32/lib/wx/keyword_ctors.rb:180:in

And one more question regarding events. What happens to events, 
assosiated to destroyed objects?

my_button = Wx::Button.new self
evt_button my_button, :my_button_click
my_button.destroy

Is this code ok, or I have to disconnect event first?

my_button = Wx::Button.new self
evt_button my_button, :my_button_click
disconnect my_button, Wx::ID_ANY, :evt_button
my_button.destroy
