I open a new TopWindow from my main Topwindow. What's the right way to clear all widgets on that new window when closing it?

Unless you have allocated memory directly with 'new' you don't have to do anything. Simply close or delete the window.

...would like to add that the cornerstone of U++ programming style is to avoid 'new' for widgets (unless there is no other way of course).

Usually, your widgets are somewhat bound to some stack frame or class, therefor destructors take care about the removing/releasing resources.
