The objective of this Lab is to develop a new Sugar activity using C# and Mono. You will learn consecutively how to use MonoDevelop to write the source code of your activity, build a package, test your activity on Sugar and on a XO.

Step 1: Create your MonoDevelop project

Launch MonoDevelop (Applications/Programming/MonoDevelop)
Create a new solution (File/New Solution…)
Choose a "C# / Gtk# 2.0 Project" template. Fill the form with "LabActivity" as name. Uncheck the "Create separate Solution Directory"

Click the "Forward" button.
In the next window, don't change any option. Don't change the Gtk# version suggested. Don't check any checkbox. Then click on "OK".

The solution is now created. We're going to setup it.

Add reference on Sugar. Right click on References, "Edit References…", choose the ".Net Assemblies" sheet. Select "Sugar.dll" in the "/home/user/Prerequisites" directory. Click on the "+Add" button then OK.

Remove the file "Main.cs" from the solution: right click on the Main.cs file, then choose "Remove" and check the "Delete from disk" box.

Step 2: Create a simple Window

Update the content of the file MainWindow.cs like below. Note than this file is available on the "/home/user/LabSource/lab1/step2" directory.

	using System;
	using System.Collections;
	using Gtk;
	using Sugar;
	
	namespace LabActivity
	{
		public class MainWindow : Sugar.Window
		{	
			public new static string activityId="";
			public new static string bundleId="";
	
			public MainWindow(string activityId, string bundleId) : base("Lab",activityId, bundleId)
			{
				this.SetDefaultSize(400, 400);
				this.Maximize();
				this.DeleteEvent += new DeleteEventHandler(OnMainWindowDelete);
	
				VBox vbox=new VBox();
				vbox.BorderWidth = 8;
				Label _text = new Label("Hello Lab Activity");
				vbox.Add(_text);
				Button _button = new Button();
				_button.Label = "Quit";
				_button.Clicked += new EventHandler(OnClick);
				vbox.Add(_button);
			
				this.Add(vbox);
	
				ShowAll();
			}
		
			void OnMainWindowDelete (object sender, DeleteEventArgs a)
			{
				Application.Quit();
				a.RetVal = true;
			}
			
			void OnClick(object sender, EventArgs a)
			{
				Application.Quit();
			}
		
			public static void Main(string[] args)
			{
				System.Console.Out.WriteLine("Lab Activity for OLPC");
				
				if (args.Length>0) {
					IEnumerator en= args.GetEnumerator();
					while (en.MoveNext()) {
 						if (en.Current.ToString().Equals("-s ugarActivityId")) { 
			 				if (en.MoveNext()) {
								activityId=en.Current.ToString();
							}
						}
						if (en.Current.ToString().Equals("-sugarBundleId")) {
							if (en.MoveNext()) {
								bundleId=en.Current.ToString();
							}
						}
					}
				}		
				
				Application.Init();
				new MainWindow(activityId, bundleId);
				Application.Run();
			}
	
		}
	}

Save the file: "File/Save"
Open the "User Interface" part of the solution, remove the file "LabActivity.MainWindow": right clic, choose "Delete", UNCHECK THE BOX "Also remove the 'MainWindow.cs'.
Launch the build "Project/Build Solution"
You don't any any error. Don't run the project for the moment.

Then copy libraries need to run the activity:

Open a Terminal window (Applications/Accessories/Terminal).
Change path to the binary directory (in /home/user/LabActivity/bin/Debug).
Create a new subdirectory named "bin" using command "mkdir bin". Change path to this new directory.
Copy in this directory all the shared libraries (.so) found in the "/home/user/Prerequisites" directory. For example with the command "cp /home/user/Prerequisites/*.so .":
- libgdksharpglue-2.so
- libgladesharpglue-2.so
- libglibsharpglue-2.so
- libgtksharpglue-2.so
- libMonoPosixHelper.so
- libpangosharpglue-2.so
- uiX11Util.so
Run the new application: "Project/Run", you should obtain this:

Click on the button to quit.
