WPF Example

From IronPython Cookbook

This is a simple introduction to Windows Presentation Foundation, the new GUI library that is part of .NET 3.0.

This code was translated from an IronRuby sample by Steve Gilham.

The WPF library is in the System.Windows namespace.

When you run this example, it will look like:

# Reference the WPF assemblies
import clr
clr.AddReferenceByName("PresentationFramework, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35")
clr.AddReferenceByName("PresentationCore, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35")
import System.Windows

# Initialization Constants
Window = System.Windows.Window
Application = System.Windows.Application
Button = System.Windows.Controls.Button
StackPanel = System.Windows.Controls.StackPanel
Label = System.Windows.Controls.Label
Thickness = System.Windows.Thickness
DropShadowBitmapEffect = System.Windows.Media.Effects.DropShadowBitmapEffect


# Create window
my_window = Window()
my_window.Title = 'Welcome to IronPython'

# Create StackPanel to Layout UI elements 
my_stack = StackPanel()
my_stack.Margin = Thickness(15)
my_window.Content = my_stack

# Create Button and add a Button Click event handler
my_button = Button()
my_button.Content = 'Push Me'
my_button.FontSize = 24
my_button.BitmapEffect = DropShadowBitmapEffect()

def clicker(sender, args):

   # Create new label
   my_message = Label()
   my_message.FontSize = 48
   my_message.Content = 'Welcome to IronPython!'

   # Add label into stack panel of controls
   my_stack.Children.Add (my_message)

my_button.Click += clicker

my_stack.Children.Add (my_button)

# Run application
my_app = Application()
my_app.Run (my_window)
