To open a view, use the call Display_Open_window_interface.open()
Further, to close the view use the call Display_Open_window_interface.close()
Last, the interface ignores two .open calls in a row. So you don't open the same window twice.
You can use a timer to keep the window open - for a time that you set- before it closes again.
NB: You can close the window “manually” via the touch screen. In this case, the interface doesn't call a .close. So, the program can only gain back control with a .close call before a .open.
For that reason, we suggest that you call a .close before you a .open call.
