GTK# 学习笔记

Choosing Gtk# or Glade#

Gtk# looks like Windows Forms and Controls, and Glade# is more like WPF, it can define the widgets in a xml file,  and load it into the application.

The Gtk# "Hello world"  application.

 using System;
 using Gtk;
 
 public class GtkHelloWorld {
  
   public static void Main() {
     Application.Init();
 
     //Create the Window
     Window myWin = new Window("My first GTK# Application! ");
     myWin.Resize(200,200);
     
     //Create a label and put some text in it.     
     Label myLabel = new Label();
     myLabel.Text = "Hello World!!!!";
          
     //Add the label to the form     
     myWin.Add(myLabel);
     
     //Show Everything     
     myWin.ShowAll();
     
     Application.Run();   
   }
 }

 compile it with command:

mcs -pkg:gtk-sharp-2.0 helloword.cs

 To use a glade file:

// file: glade.cs
using System;
using Gtk;
using Glade;
public class GladeApp
{
        public static void Main (string[] args)
        {
                new GladeApp (args);
        }
 
        public GladeApp (string[] args) 
        {
                Application.Init();
 
                Glade.XML gxml = new Glade.XML (null, "gui.glade", "window1", null);
                gxml.Autoconnect (this);
                Application.Run();
        }
}

 compile it with command:

mcs -pkg:glade-sharp-2.0 -resource:gui.glade glade.cs

 use -resource:gui.glade option to make it as embedded resource. Or just leave it in the file system,

and use the following code to load it.

Glade.XML gxml = new Glade.XML ("./gui.glade", "window1", null);

 add private member, then they can be used in the program, and can add event handler to catch widget events. 

[Widget]      
Button button1;
       
[Widget]
Label label1;

button1.Clicked += OnPressButtonEvent;
              
public void OnPressButtonEvent( object  o, EventArgs e)
{
   Console.WriteLine("Button press");
   label1.Text ="Mono"; 
}

 or add the widget events in the glade designer, and add the handler code with the same method name:

void on_button1_clicked(object o, EventArgs e)
{
}
