Fixed in latest release

Hi Ado,

I am still able to verify this ALT+TAB issue with AvalonDock 2.0 build 94905. I was unable to re-gain the document focus after tabbing away and back with ALT+TAB (as described above). I tested this in:

AvalonDock.MVVMTestApp
AvalonDock.TestApp

The selection is lost when I tab back to the AvalonDock app and the cursor is invisible.

I have finally found a workaround solution that works for me as long as I do not use an undocked document/tool window:

I subscripe to the Activated/deactivated event in the MainWindow class and make an attempt
at restoring the focus whenever the window gets activated (with ALT+TAB) for example. This
works in my sample app with AvalonEdit and in your MVVM Test App with the standard WPF
textbox.

I know this is most likely not what you would want to do eventually but at least the application
now starts to be a lot more useful - maybe you can add this into your sample app until we have
a better solution ...?

Thanks for your great work :) This is really cool to work with *-)

------------------------- Code Snippet --------------------------------------------

    public MainWindow()
    {
        InitializeComponent();

        this.DataContext = Workspace.This;

        this.Activated += new EventHandler(MainWindow_Activated);
        this.Deactivated += new EventHandler(MainWindow_Deactivated);
    }

    IInputElement RestoredFocus = null;
    void MainWindow_Deactivated(object sender, EventArgs e)
    {
      this.RestoredFocus = System.Windows.Input.Keyboard.FocusedElement;

      string FocusName = "(null)";
      string FocusType = "(null)";

      if (this.RestoredFocus != null)
      {
        try
        {
          System.Console.WriteLine("MainWindow_Deactivated Storing Focus Type: {0} Name: {1}", FocusType, FocusName);

          FocusName = (this.RestoredFocus as FrameworkElement).Name;
          FocusType = this.RestoredFocus.GetType().FullName;
        }
        catch
        {
        }
      }
    }

    void MainWindow_Activated(object sender, EventArgs e)
    {
      if (this.RestoredFocus != null)
      {
        try
        {
          this.RestoredFocus.Focus();
          System.Console.WriteLine("MainWindow_Activated restoring focus");
        }
        catch (Exception)
        {

          throw;
        }
      }
    }

I just found a better solution:

Just add

Keyboard.DefaultRestoreFocusMode = RestoreFocusMode.Auto;

into the constructor of the MainWindow after the this.InitializeComponent(); call and ALT+TAB works as it should.
