Multiple processes rendering to one window

The new Stainless browser renders each webpage in a separate subprocess. Which is absolutely great as one webpage crashing will only crash its process, sparing the other webpages.

How does it work ? Quartz debug to the rescue … each Stainless subprocess renders the whole window ! Interface elements, like the tab list, are duplicated in each subprocess. This is a straightforward, clean implementation. I find that solution much more elegant than rendering to an image and moving it to the parent process. Hats off to the Stainless devs, this is really a great trick !

Hi ! I'm learning Cocoa to (hopefully !) become an indie developer.

I've written software all my professional life, in C++, PHP, Javascript. I've designed websites and web interfaces. My last venture went into flames as clients were happy but didn't like paying very much.

I've had little luck in the B2B world, I'm hoping for a better future writing Mac applications.
