Description:

Vterm now emits 'resize' signal upon terminal resize, with a (height, width) tuple of the new size.

examples/terminal.py has been updated to handle the 'resize' signal, and uses it to display the terminal height x width. This is useful for testing purposes if you want to test vterm at a particular size.

Code seem to work well. I attempted to add the following test to tests/test_vterm.py, but I have not been successful in getting it to work properly (test always fails to receive the signal)
Any suggestions on how to make this test work properly are appreciated.

    def test_resize_signal(self):
        self.connect_signal('resize')
        self.resize(80, 24)
        self.expect_signal('resize')
        self.disconnect_signal('resize')

I'll try to investigate tests ASAP

Thanks. Good to see you back! Hoping for a new Urwid release in the near future?

Looks like need to release "binary only 3.7 ≤ python ≤ 3.11and later fix python 3.12+ unicode compatibility (new API was in python 3 almost forever, old was because of python 2)

Issue for tests write was created (for resize test is a bit not trivial)
