Ser ut som du borde initiera GTK först?

Syftar på att de skriver om "IA__g_type_init()" i debuggen

ok nu är det mesta på plats..
nu skall jag bara komma på hur man får den att uppdatera tiden... -_-... några idéer?

using System;
using Gtk;
using GLib; //behöver jag dig?

namespace GTKtest
{
	
	//das program
	
	public class Program
	{
		public static void Main(String[] args)
		{
			Application.Init();
			
			MainWindow wind = new MainWindow("Stuff");
			wind.ShowAll();
			
			Application.Run();
			
		}
		
		
	}
	
	
	//window
	
	class MainWindow : Window
	{
		public MainWindow(string title) : base(title)
		{
			
			
			this.SetDefaultSize(250, 100);
			this.DeleteEvent += new DeleteEventHandler(MainWindow_delete);
			
			Label lbTitle = new Label("The Epoch time is now:");
			Label lbTime = new Label();
			
			
			
			lbTime.Text = timeToEpoch.toEpoch().ToString();
			
		 	VBox boxxer1 = new VBox();
			
			boxxer1.Add(lbTitle);
			boxxer1.Add(lbTime);
			
			this.Add(boxxer1);
			
		}
		
		void MainWindow_delete(object sender, DeleteEventArgs args)
		{
			
			Application.Quit();
			args.RetVal = true;
			
		}
		
	}
	
	class timeToEpoch
	{
		public static int toEpoch()
		{
			int eTime;
			
			TimeSpan t = (DateTime.UtcNow - new DateTime(1970,1,1));
			
			eTime = (int) t.TotalSeconds;
			
			return(eTime);
		}
		
		
	}
	
	
}

I vanligt c# hade du gjort en timer med 1000 ms.
Vet ej om det går att använda vanliga timers i Gtk, sök på system.timers.timer

mjo, men hur ritar jag om?

jag la till en knapp som jag tänkt att använda för att rita om tiden, och en eventhandeler

{
//stuff//
   btnTick.Clicked += entTimeRedraw; //tryck på knappen för att rita om entTime
    //mer skit//
}
void entTimeRedraw(object sender, EventArgs e)
{
    //vet inte...
}

(språkmässigt är det ingen sklinad, oberoende på vilden CLI man använder...)

[edit]
om du vill testa på hur mono är: http://www.go-mono.com/mono-downloads/download.html
gtk-sharp finns även till .Net

[edit2]
monodevelop RC till windows: http://monodevelop.com/Download/Windows_Preview

Är det inte bara att sätta värdet på textfältet igen? Så är det i vanliga .net, där behöver du inte explicit ropa på RePaint()

lbTime.Text = timeToEpoch.toEpoch().ToString();

trodde det, men jag kommer inte åt entTime från entTimeRedraw-metoden..

jaha, antar att du menar lbTime... Du måste lyfta ut deklarationen av den variablen till en klassvariabel... såhär:

namespace GTKtest
{
	
	//das program
	
	public class Program
	{
		public static void Main(String[] args)
		{
			Application.Init();
			
			MainWindow wind = new MainWindow("Stuff");
			wind.ShowAll();
			
			Application.Run();
			
		}
		
		
	}
	
	
	//window
	
	class MainWindow : Window
	{
                private Label lbTime;

		public MainWindow(string title) : base(title)
		{
			
			
			this.SetDefaultSize(250, 100);
			this.DeleteEvent += new DeleteEventHandler(MainWindow_delete);
			
			Label lbTitle = new Label("The Epoch time is now:");
			lbTime = new Label();
			
			
			
			lbTime.Text = timeToEpoch.toEpoch().ToString();
			
		 	VBox boxxer1 = new VBox();

Då kommer du sen åt den i entTimeRedraw

tack. det fungerad...

men nu har jag ett annat problem, hur skall jag göra för att få tiden att uppdatera automatiskt?

Som kurre var inne på, timers. Läs på lite på msdn

så här set i alla fall exemplet på mono documentation ut:

using System;
using System.Timers;

public class TimerExample
{
	private static System.Timers.Timer ourTimer;

	public static void Main()
	{
		ourTimer = new System.Timers.Timer();

		// attach to the Elapsed event.
		ourTimer.Elapsed += new ElapsedEventHandler(OnTimerElapsed);

		// make our timer interval 1 second
		ourTimer.Interval = 1000;
		
		// don't forget to enable the timer!
		// we could also call ourTimer.Start() here; they both have the same effect 
		// (starting the timer).
		ourTimer.Enabled = true;

		Console.WriteLine("Waiting 10 seconds before exit...");
		System.Threading.Thread.Sleep(10000);
	}

	private static void OnTimerElapsed(object sender, ElapsedEventArgs e)
	{
		Console.WriteLine("Timer elapsed at: " + e.SignalTime.ToLongTimeString());
	}
}

och min kod:

using System;
using System.Timers;
using Gtk;
using GLib;

namespace GTKtest
{
	
	//das program
	
	public class Program
	{
		public static void Main(String[] args)
		{
			Application.Init();
			
			MainWindow wind = new MainWindow("Stuff");
			wind.ShowAll();
			
			Application.Run();
			
		}
		
		
	}
	
	
	//window
	
	class MainWindow : Window
	{
		
		private Entry entTime;
		
		public MainWindow(string title) : base(title)
		{
			
			
			this.SetDefaultSize(250, 100);
			this.DeleteEvent += new DeleteEventHandler(MainWindow_delete);
			
			Label lbTitle = new Label("The Epoch time is now:");
			entTime = new Entry();
			
			// Button btnTick = new Button("tick");
			
			// btnTick.Clicked += entTimeRedraw; //tryck på knappen för att rita om entTime
			
			entTime.Text = timeToEpoch.toEpoch().ToString();
			
			System.Timers.Timer tiimeer = new System.Timers.Timer();
			tiimeer.Interval = 666;
			tiimeer.Enabled = true;
			tiimeer.Elapsed += ElapsedEventHandler(entTimeRedraw); // <------ här är det fel?!?! <------
			
			VBox boxxer1 = new VBox();
			HBox boxxer2 = new HBox();
			
			boxxer2.Add(entTime);
			//boxxer2.Add(btnTick);
			
			boxxer1.Add(lbTitle);
			boxxer1.Add(boxxer2);
			
			this.Add(boxxer1);
			
		}


		private static void entTimeRedraw(object sender, ElapsedEventArgs e)
		{
			entTime.Text = timeToEpoch.toEpoch().ToString();
		}
		
		
		
		void MainWindow_delete(object sender, DeleteEventArgs args)
		{
			
			Application.Quit();
			args.RetVal = true;
			
		}
		
	}
	
	// stuff.... and p0|2|\|
	
	class timeToEpoch
	{
		public static int toEpoch()
		{
			int eTime;
			
			TimeSpan t = (DateTime.UtcNow - new DateTime(1970,1,1));
			
			eTime = (int) t.TotalSeconds;
			
			return(eTime);
		}
		
		
	}
	
	
}

det felmedeandet som jag får är:

[Task:File=/home/username/mono-projects/GTK test/GTK test/Main.cs, Line=55, Column=44, Type=Error, Priority=Normal, Description=Expression denotes a `type', where a `variable', `value' or `method group' was expected(CS0119)]

I sådana här tillfällen önskar jag att jag kommer håg mina programmerings lektioner.
försig, så var det java, men jaja...

Terminologi är inte min starka sida, logik är mer min sak...

prova att ändra:
tiimeer.Enabled = true;
tiimeer.Elapsed += ElapsedEventHandler(entTimeRedraw); // <------ här är det fel?!?! <------

till:
tiimeer.Elapsed += ElapsedEventHandler(entTimeRedraw); // <------ här är det fel?!?! <------
tiimeer.Enabled = true;

sånt där kan ställa till det ibland...

hmm, det kan vara så att du inte får uppdatera komponenter som ligger i "GUI-tråden" med en annan tråd än "huvud-tråden". Har dessvärre inget lösningsförslag på det då jag aldrig jobbat med GTK. Kolla monos forum eller nått sånt...

hittade problemet -_- .....
var så att man kunde inte ha en
entTime.Text = timeToEpoch.toEpoch().ToString();
samtidigt som man uppdaterade tiden... -_-

[edit]
0_o...
nu chrachar den om jag dubbel klickar i Entry rutan ?!?!?
