You need to match the signature of Application.Idle. But once you have the
right signature += should work. It looks like Idle is just an EventHandler so:
def MyIdle(self, sender, eventArgs):
self.Invalidate()
Application.Idle += self.MyIdle
Should work. And to make it more like the C# version you can use a lambda:
Application.Idle += lambda sender, ea: self.Invalidate()

Subject: [IronPython] Delegates
I'm trying to put Xna on a Windows Form and the best idea that I've found so
far was at
http://creators.xna.com/Headlines/developmentaspx/archive/2007/01/01/WinForms-Series-1_3A00_--Graphics-Device.aspx.
In a nut shell it's quite easy to translate the C# code to IronPython to see
if it will actually work for IronPython. That is until the C# code:
C#
// Hook the idle event to constantly redraw our animation.
Application.Idle += delegate { Invalidate(); };
This makes it so the Xna control that you create it constantly redrawn, not
just every button click or other event. This code is found in the
SpinningTriangleControl.cs of the zip
file if you want to see more of how it works.
My question is how do I create a delegate or equivalent in IronPython? I've
tried using System.Delegate, but I'm not sure how to use it correctly. Also
I've tried just using
Application.Idle += self.Invalidate (called or uncalled) and that doesn't work.
