I know that begindraw clear all internal buffer, and begindraw is neccesary for each new draw. But I want draw only a specific area of screen. For example, I have a function that put in the top of screen the date and time/seconds, and other function that put some text in the middle of screen. Now when draw the text in the middle of screen clear the date and time in the top. Is possible have a new begindraw that not clear all screen?
I hope I have been clear in my description.
