CGContextTranslateCTM Question

'Morning All:

(Now that the power's back on... 23.5 hours without and I had just filled the fridge...)

I am back to trying to get the this problem with SplitView and non-compositing windows straightened out.

If I don't do a CGContextTranslateCTM() when drawing, the splitters are drawn upside down and the sections of my window appear to be the correct proportions. Just the wrong way around.

If I do a CGContextTranslateCTM(x, 0.0f, splitRect.Height()) for the vertical and CGContextTranslateCTM(x, splitRect.Width(), -1.0f) for the horizontal, things are not drawn properly. The vertical splitter is in the wrong position, and the horizontal is no where to be seen.

So, if I've move the origin and coordinate system around, doesn't the actual rectangle that defines the splitter also have to be adjusted? How to do that?

Or are the parameters to CGContextTranslateCTM wrong? (It's been a long time since I've done matrix math, and am a little rusty).

Any hints would be appreciated...


Thanks

John
