The alternative is to do what you've done below. In fact, this is what 
wxWidgets does anyway on Windows and OS X; the "wxFilePicker" is only a 
native control on GTK. This is the main reason the class isn't ported.

I'm not clear which dialog you mean, or where the FilePicker goes. If 
all you want to do is allow the user to choose a file to open (like an 
"Open" item in a menu), you don't need FilePicker. The simplest way is 
just to use Wx::file_selector function

evt_menu(Wx::ID_OPEN) do
  file_to_open = Wx::file_selector('Choose a file')
  # .... note that file_to_open will be an empty string if the user 
chose Cancel
end

For more control, use Wx::FileDialog - see the docs and the dialog sample.

dlg = MyDialog.new(self, ...)
dlg.evt_close { | evt | puts 'my child dialog has closed'; evt.skip }

But conventionally, modal (blocking) dialogs communicate the user's 
selection back to the calling frame through the return value of 
show_modal, eg:

dlg = Wx::FileDialog.newl(self, ...)
result = dlg.show_modal
if result = Wx::ID_OK
  puts 'you chose' + dlg.file
else
  puts 'you cancelled'
end
end

You should definitely make a modal dialog a child of the calling frame. 
I'd suggest you have a look at the dialogs.rb sample to see how it's done.
