How to redisplay when terminal size is changed?

[failable]

When terminal size is changed it won't redisplay automatically. How can I trigger redisplay?

[AlFaizCodes]

When the terminal is resized, the operating system sends a SIGWINCH signal to the application. To redisplay content, handle this signal, read the new terminal size, clear the screen, and redraw the UI according to the updated dimensions. Most terminal libraries (like ncurses) provide built-in support for handling resize events.
