PyPy.NET goes Windows Forms

2008-01-19 22:23

After having spent the last few days on understanding PyPy's JIT, today I went back hacking the clr module. As a result, it is now possible to import and use external assemblies from pypy-cli, including Windows Forms

Here is a screenshot of the result you get by typing the following at the pypy-cli interactive prompt:

>>>> import clr
>>>> clr.AddReferenceByPartialName("System.Windows.Forms")
>>>> clr.AddReferenceByPartialName("System.Drawing")
>>>> from System.Windows.Forms import Application, Form, Label
>>>> from System.Drawing import Point
>>>>
>>>> frm = Form()
>>>> frm.Text = "The first pypy-cli Windows Forms app ever"
>>>> lbl = Label()
>>>> lbl.Text = "Hello World!"
>>>> lbl.AutoSize = True
>>>> lbl.Location = Point(100, 100)
>>>> frm.Controls.Add(lbl)
>>>> Application.Run(frm)

Unfortunately at the moment you can't do much more than this, because we still miss support for delegates and so it's not possibile to handle events. Still, it's a step in the right direction :-).
