I’m using Tcl/Tk to build a GUI, for Linux environment and I saw that it’s possible to “catch” a press on the ‘x’ button of the window (The button on the top right corner that closes the program).
How can I catch those events?

To take control of requests to delete a window, configure a suitable protocol handler:
The default behavior (i.e., if the protocol handler is the empty string) is to just
destroythe toplevel to which the request was made.
