event in different threaded window

I created a separate project. Now i want to start this project in a new threaded window. That's not diffucult. What i dont have a clue is how to wire and event to pass data to the new threaded window. Who can help with this?

This is my code to start my new window in a different thread.

Thread newWindowThread = new Thread(new ThreadStart( () =>
{
    // Create our context, and install it:
    SynchronizationContext.SetSynchronizationContext(
        new DispatcherSynchronizationContext(
            Dispatcher.CurrentDispatcher));

    Window1 tempWindow = new Window1();
    // When the window closes, shut down the dispatcher
    tempWindow.Closed += (s,e) => 
       Dispatcher.CurrentDispatcher.BeginInvokeShutdown(DispatcherPriority.Background);

    tempWindow.Show();
    // Start the Dispatcher Processing
    System.Windows.Threading.Dispatcher.Run();
}));
