Re: [Fxruby-users] New tab item not visible via block

[Rich <ri...@li...>]

Are you instantiating Objects without 'show'ing them?

Everything that is instantiated before the MainWindow is shown will be shown
along with the MainWindow.

Anything else that is created while the application is running needs to be
manually shown.
