CHAPTER 8
Creating WindoWs Forms appliCations
# Configure btnFireEvent
self.btnFireEvent = System.Windows.Forms.Button()
self.btnFireEvent.Text = “&Fire Event”
self.btnFireEvent.Location = System.Drawing.Point(263, 13)
# Configure btnQuit
self.btnQuit = System.Windows.Forms.Button()
self.btnQuit.Text = “&Quit”
self.btnQuit.Location = System.Drawing.Point(263, 43)
# Add the controls to the form.
self.Controls.Add(self.btnFireEvent)
self.Controls.Add(self.btnQuit)
It’s generally a good practice to keep the event, form, and operational code 
separate. Doing so will make the application easier to debug later. This example 
actually uses three separate files, even though it’s a very simple example. Make 
sure you follow this principle when creating events of your own.
As you can see, this form is a very simple version of
the other forms used so far in this chapter. All it does
is provide access to two buttons: one to fire the event
and the other to close the form. Figure 8-9 shows the
output from this code.
Running the Code
It’s time to try out the new event and its associated test 
form. Listing 8-7 shows the code required for this part of 
the example.
lISTINg 8-7: 
 Testing the event class
# Set up the path to the .NET Framework. 
import sys
sys.path.append(‘C:\\WINDOWS\\Microsoft.NET\\Framework\\v2.0.50727’)
# Make clr accessible.
import clr
# Add any required references.
clr.AddReference(‘System.Windows.Forms.DLL’)
FIguRE 8-9: 
A simple form used to test the 
custom event and associated handler.
