[IronPython] overriding methods defined in C# classes

[Simon Dahlbacka]

Shouldn't your c# methods be protected virtual to be overridable?

I set out to do just that and stumbled upon a problem:

I generated Windows form in C#, compiled into assembly (ip_cl1), copied to
python project folder:

clr.AddReference('ip_cl1')
..
from ip_cl1 import Form1


class Form1Inh(Form1):
      def __init__(self):
          Form1.__init__(self)

      def comboBox1_SelectedIndexChanged(self, sender, event):
          self.BackColor = Color.Azure

This doesn't work, i.e. method comboBox1_SelectedIndexChanged doesn't get
called. I have to expicitly add EventHandler in Python:

class Form1Inh(Form1):
      def __init__(self):
          Form1.__init__(self)
          self.box1.SelectedIndexChanged +=
EventHandler(self.comboBox1_SelectedIndexChanged);

      def comboBox1_SelectedIndexChanged(self, sender, event):
          self.BackColor = Color.Azure


Is there some way of simply overriding methods in Python so that they do get
called by form events?




In Form1.cs I have:


namespace ip_cl1
{
   public partial class Form1 : Form
   {
       public Form1()
       {
           InitializeComponent();
       }

       protected void box1_SelectedIndexChanged(object sender, EventArgs e)
       {

       }

       protected void comboBox1_SelectedIndexChanged(object sender,
EventArgs e)
       {

       }
   }
}
