This class is a simple implementation of Terminal.ResizeListener which will keep track of the size of the terminal
and let you know if the terminal has been resized since you last checked. This can be useful to avoid threading
problems with the resize callback when your application is using a main event loop.
public SimpleTerminalResizeListener(TerminalSize initialSize)
Creates a new SimpleTerminalResizeListener
initialSize - Before any resize event, this listener doesn't know the size of the terminal. By supplying a
value here, you control what getLastKnownSize() will return if invoked before any resize events has reached us.
public boolean isTerminalResized()
Checks if the terminal was resized since the last time this method was called. If this is the first time calling
this method, the result is going to be based on if the terminal has been resized since this listener was attached
to the Terminal.
The terminal has changed its size, most likely because the user has resized the window. This callback is
invoked by something inside the lanterna library, it could be a signal handler thread, it could be the AWT
thread, it could be something else, so please be careful with what kind of operation you do in here. Also,
make sure not to take too long before returning. Best practice would be to update an internal status in your
program to mark that the terminal has been resized (possibly along with the new size) and then in your main
loop you deal with this at the beginning of each redraw.
