I need to display a great deal of data into a window. I do not want to draw it all in each time the window gets scrolled. I was going to take the top and bottom of the window and then just draw the necessary data. Now here is the problem: I get a NEGATIVE value for the height of my window. The code looks like this ( WindowData is a WindowPeek ): WindowHeight := WindowData^.port.portrect.top - WindowData.port.portrect.bottom; I have no idea why this is a negative number but I checked it using MacsBug. BTW: Has anyone received the new technotes from Apple (The reprints). All help will be greatly appreciated.
