[MonoDevelop] What is the correct way of closing a Gtk dialog?

[simon.n.lindgren at gmail.com]

Ah, I think you misunderstood a bit(or maybe I didn't explain that
good). I have made new stetic dialog and I use an overloaded Run() to
display it. When the user presses any of the two buttons, buttonOk and
buttonCancel, the dialog should close i.e. the Run method should return
to the caller again. How do I do that? here's the current eventhandling
code:

public partial class PromtingDialog : Gtk.Dialog
{
	
	public PromtingDialog(string title, string promt)
	{
		this.Build();
		labelQuestion.Text = promt;
		this.Title = title;
	}
	
	public virtual int Run(out string response)
	{
		int retVal = base.Run();
		response = this.response;
		return retVal;
	}

	protected virtual void buttonOk_Clicked (object sender,
System.EventArgs e)
	{
		response = entryResponse.Text;
		this.Destroy();
	}

	protected virtual void buttonCancel_Clicked (object sender,
System.EventArgs e)
	{
		response = "";
		this.Destroy();
	}
	
	private string response = "";
}
