- Prison Code Breaker Diary -

Programming .NET is one of the first thing I've learned myself long ago, but only available in Windows Operating System.
Somehow, the Mono Project has made .NET Framework become a cross-platform environment that you can freely programming .NET for Windows, Linux, MacOS...in that system directly. Also, you can write a .NET program for Linux under Windows and vice-versa. It's really a great achievement that Mono Project has reached. I expect that Mono Project will achieve more impressive goals with .NET technology in the future as it develops.
I write this guide as a journal in programming .NET under Linux environment by using Mono Project.
You may take this as a reference for Gtk#.

1 - Documentation and Reference:
Here the list that I read and reference from:
Gtk# Tutorial Page by Mono
Mono Documentation Library (equivalent to MSDN)
Mono: A Developer's Notebook (Edd Dumbill, Niel M. Bornstein) - A great book, worth to buy for two reasons:
+ It's the only book on Mono up to this time.
+ It's written as a developer's journal style, so it's really easy to catch the authors' mind concepts.

2 - Programming Gtk# Journal

Lesson 1: Say Hello
Lesson 2: Hello Gtk# (using Form)
Lesson 3: MonoDevelop IDE vs. manual text coding w/ commands. (to be updated...)


Feel free to comment!
Have fun!

Download Project

We do the same thing with Lesson 1 but this time we use form for better GUI.
This is the source code, self-explained fully-commented.

using System;
using Gtk;

public class Lesson_2
{

 public static void Main() {
  
  Application.Init();
  
  // create a window
  Window window = new Window("Lesson 2: Say hello with Gtk# Form");
  window.Resize(400, 40);
  
  // create a label
  Label label = new Label("Hello Gtk# .NET");
  // add label to the form
  window.Add(label);
  // show form and its widgets
  window.ShowAll();
  
  Application.Run();
 }
}

Build and run, this is result:


Have fun!

Download Project: Lesson 1 - Say Hello Gtk#

First, open MonoDevelop and create a new empty project. Then, add an empty class file into project. Copy this code below to the file:

using System;

public class Lesson_1 {

public static void Main() {
Console.WriteLine("Lesson 1: Hello Gtk#! It's so wonderful!");
}
}

If you already know C#, you, hence, know what it means.

Now click on the menu Build -> Build Solution or F8.
Click menu Run -> Run or Ctrl+F5.
You will have result like this:

The result is shown under the Application Output textbox.

However, if you want to compile a single C# file or a C# project manually, then do this.

Open the terminal:

terminal> mcs -pkg:gtk-sharp-2.0 Main.cs

A file named Main.exe will be generated. In order to run this file you have to use mono utility:

terminal> mono Main.exe

The result will show up exactly how it is while using MonoDevelop.

Have fun!
