It seems that something wrong with typography system in Cocoa.

It depends on who is doing the drawing. NSTextView is an NSView subclass and
you can override drawRect: just like any NSView. The Cocoa text system,

Dear all,
I am a new Cocoa developer on iPhone/iPad. I plan to use NSOperationQueue to
achieve the goal of concurrency. I am not sure if it is better since I also
know GCD is available.
Moreover, I didn't notice that Cocoa provided developers with
synchronization controlling mechanisms. Is it tru

I need to wait, while the image is drawn (drawRect method is actually
called by the framework) from a different thread that supplies frames.
I am drawing images just to see that the output is correct, in the
final application i don't need them to be drawn on the screen but
saved into a file

Hi
I have a CVPixelBuffer with some background picture.
I need to draw on this background some foreground image. I don't need
to preserve the initial CVPixelBuffer's content - i just need to add a
small foreground watermark onto that buffer.
CIImage does allow to create an image from CVPixelBuffer
Why not use the production of a frame from your secondary thread to drive
calling -setNeedsDisplay on your view? Then you don't need to block any thread
(and you really really do not want to block the main thread anyway).

the pixel format of the CVPixelBufferRef is k32BGRAPixelFormat

It should work. The list of supported format is here:

Thanks, Now it constantly returns (0;0). Why would that happen at all?
Maybe i don't have enough permissions to read the cursor position?
(like, need to have some accessibility things enabled)?

May this is just a wrong function to retrieve the cursor's position?
Or it doesnt work for some older builds of OX X 10.6.x ?

Oh, I thought you were looking for the cursor's hotspot, not its location.
NSPoint pos = [NSEvent mouseLocation];

Hi,
I have a program that saves its data (an array of dictionaries) as a plist in

Now this array gets manipulated a lot while working with the program.
And currently I save the array to disk every time something in th
