[IronPython] Running applications vs. forms?

The object you pass to Application.Run should derive from Form, not
Application.  In your example below, you should eliminate the class MyApp
and pass either Form1 or Form2.

Subject: [IronPython] Running applications vs. forms?

 

To clarify my earlier message-

If I want to create a non-trivial application, I will have several forms and
dialogs. My(apparently broken) understanding is that I would create a class
representing the application and pass that to the Application.Run(method).
For example, the tiny app here:


import clr
clr.AddReference('System.Windows.Forms')
clr.AddReference('System.Drawing')

from System.Windows.Forms import Form,Application

class Form1(Form):
    pass
class Form2(Form):
    pass
class MyApp(Application):
    pass
a = MyApp()            
Application.Run(a)


Produces 'TypeError: cannot derive from sealed or value types'.
Alternatively, If I create a class with no inheritance, I get 'TypeError:
bad args for method'. What is the correct way to do this?
