Cocoa/Objective-C Question

Hi everyone,

Firstly I wanted to say thank you to all the contributors who have provided good advice for myself and others to use, while some people might not be thankful, I assure you that there are many of us out there who really do appreciate the help given.

I have written a small cocoa app which is basically just a simple user interface. It consists of a window with shapes that you can draw inside it. It also has scrollbars for when the background (or image) is smaller than the window itself. The problem I am having is that when I click and drag a shape (to move it), it does not automatically scroll (for example, if I click inside the shape and drag the mouse down below the bottom of the window, it will not scroll down as I would like it to).

Any help would be greatly appreciated.

p.s. I have googled all over the place for this but the closest thing I have found is grab-scrolling code on this page: http://iratescotsman.com/products/source/)

Thanks!

NSView:
- (BOOL)scrollRectToVisible:(NSRect)aRect

Should do what you want, if you call this periodically with the rect of the image you are dragging...
