Demo - 2 simultaneous windows using read_all_window
|
|
|
|
Both windows are immediately visible. Each window updates the other.
|
|
|
|
There's an added capability to "re-open" window 2 should it be closed. This is done by simply calling the make_win2 function
|
|
again when the button is pressed in window 1.
|
|
|
|
The program exits when both windows have been closed
