    <summary>Creates popup windows.</summary>
    <remarks>
      <para>
        <see cref="T:Gtk.Dialog" /> boxes are a convenient way to prompt the user for a small amount of input, eg. to display a message, ask a question, or anything else that does not require extensive effort by the user.</para>
      <para>Gtk# treats a dialog as a window split vertically. The top section is a <see cref="T:Gtk.VBox" />, and is where widgets such as a <see cref="T:Gtk.Label" /> or an <see cref="T:Gtk.Entry" /> should be packed. The bottom area is known as the <see cref="P:Gtk.Dialog.ActionArea" />. This is generally used for packing buttons into the dialog which may perform functions such as cancel, ok, or apply. The two areas are separated by a <see cref="T:Gtk.HSeparator" />.</para>
      <para>The two primary areas of a dialog can be accessed as the <see cref="P:Gtk.Dialog.Vbox" /> property and the <see cref="P:Gtk.Dialog.ActionArea" /> property. To set the dialog to be modal, use the <see cref="P:Gtk.Window.Modal" /> property.</para>
      <para>If you want to block waiting for a dialog to return before returning control flow to your code, you can call <see cref="M:Gtk.Dialog.Run" />. This function enters a recursive main loop and waits for the user to respond to the dialog, returning the <see cref="T:Gtk.ResponseType" /> corresponding to the <see cref="T:Gtk.Button" /> the user clicked.</para>
      <para>For a simple dialog, you would probably use <see cref="T:Gtk.MessageDialog" /> to save yourself some effort. However, you would need to create the <see cref="T:Gtk.Dialog" /> contents manually if you had more than a simple message in the <see cref="T:Gtk.Dialog" />.</para>

        <code lang="C#">

                Waits for the <see cref="E:Gtk.Dialog.Response" /> event or the <see cref="T:Gtk.Dialog" /> to be destroyed.
                If the <see cref="T:Gtk.Dialog" /> is destroyed during the call to <see cref="M:Gtk.Dialog.Run()" />, <see cref="T:Gtk.Dialog" /> returns <see cref="F:Gtk.ResponseType.None" />.
                Otherwise, it returns the response ID from the <see cref="E:Gtk.Dialog.Response" /> event.
                Before entering the recursive main loop, <see cref="M:Gtk.Dialog.Run()" /> calls <see cref="M:Gtk.Widget.Show()" /> on the <see cref="T:Gtk.Dialog" /> for you.
                Note that you still need to show any children of the <see cref="T:Gtk.Dialog" /> yourself.

          <para>
                During <see cref="M:Gtk.Dialog.Run()" />, the default behavior of <see cref="E:Gtk.Window.DeleteEvent" /> is disabled;
                if the <see cref="T:Gtk.Dialog" /> receives <see cref="E:Gtk.Window.DeleteEvent" />, it will not be destroyed as usual, and <see cref="M:Gtk.Dialog.Run()" /> will return <see cref="F:Gtk.ResponseType.DeleteEvent" />.
                Also, during <see cref="M:Gtk.Dialog.Run()" /> the <see cref="T:Gtk.Dialog" /> will be modal.
                You can force <see cref="M:Gtk.Dialog.Run()" /> to return at any time by calling <see cref="M:Gtk.Dialog.Respond" /> to emit the <see cref="E:Gtk.Dialog.Response" /> event.
                Destroying the <see cref="T:Gtk.Dialog" /> during <see cref="M:Gtk.Dialog.Run()" /> is a very bad idea, because your post-run code will not know whether the <see cref="T:Gtk.Dialog" /> was destroyed or not.
            </para>
          <para>
                After <see cref="M:Gtk.Dialog.Run()" /> returns, you are responsible for hiding or destroying the <see cref="T:Gtk.Dialog" /> if you wish to do so.
