GTK # Study Notes

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. 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)
{
}
