I have two problems:
First. the program refreshes the screen only when I move the mouse, while when I do not move it, it stands still and does not display any messages.
Second. I have several text lines set up in exactly the same x, y position. Only at the end of the program do I have the application windowApplication.display () ;. Then these texts are displayed on top of each other. How to do this to eliminate this problem of text overlapping.
