How from Application to address to an open window?

Question

WPF

I have an application that contains a TextBox and a Button. It is necessary that by clicking on the button in the TextBox all events that have occurred with the application since the launch are displayed.
I receive events in the App class, but I can't display it in a TextBlock

Answer 1

The Application class has a Windows property https://docs.microsoft.com/ru-ru/dotnet/api/system...
from which you can get the desired window and display the result by assigning the Text property to the TextBlock
