Basic C# GTK program

In a previous example we created a simple console program, in this example we will create a basic GUI program. To do this we need to install GTK.

Lets begin by installing GTK for mono

Source code

sudo apt-get install gtk-sharp2

Create a folder and a file called gtkexample as follows

Source code

mkdir gtkexample
cd gtkexample
geany gtkexample.cs

Now enter the following code

Source code

using Gtk;
using System;
class gtkHello {
static void Main()
{
Application.Init ();
Window gtkWin = new Window ("GTK Example");
gtkWin.Show();
Application.Run();
}
}

Now open the file manager, navigate to the gtkexample folder. This should look like this

Now double click on the gtkexample.exe. You should see something like the following
