我正在从另一个对话框中加入 Gtk.Dialog 关闭事件,如下所示:
AddTask dialog = new AddTask (task); //AddTask inherits from Gtk.Dialog
dialog.Close += HandleDialogClose;
dialog.Show();
void HandleDialogClose (object sender, EventArgs e)
{
Refresh(); //Does some stuff in the calling dialog
}
当我关闭对话框(我在上面创建的那个)时,永远不会触发 HandleDialogClose 事件。知道为什么吗?
这是一些示例代码,我现在自己解决了。我正在登记 Close() 事件,而我应该登记 Destroyed() 事件。下面的代码现在可以工作(注释的代码是不工作的)。
using System;
using Gtk;
namespace test
{
public partial class MainWindow: Gtk.Window
{
public MainWindow (): base (Gtk.WindowType.Toplevel)
{
Build ();
Button button1 = new Button();
button1.Label = "Open About";
this.Add(button1);
button1.Show();
button1.Clicked += HandleButton1Clicked;
}
void HandleButton1Clicked (object sender, EventArgs e)
{
About dialog = new About();
//dialog.Close += HandleAboutClose;
dialog.Destroyed += HandleAboutClose;
dialog.Show();
}
protected void OnDeleteEvent (object sender, DeleteEventArgs a)
{
Application.Quit ();
a.RetVal = true;
}
void HandleAboutClose (object sender, EventArgs e)
{
Console.WriteLine("About Closed");
}
}
}
