objective c - How does "Cinch App" do it? -

If you are not familiar with Sync, then this is an application on the Mac App Store which lets you make any windows half / full Screen size If you drag the window to the edge of the screen Exactly like functionality in Windows 7

Now I have a question, how is this done? Whenever a window is being pulled (all the windows, only app-owned windows from which the code is running) I have to appear above the coco API in search of information / representative methods, but it was not found. Viewed in Core Graphics API ... Quartz Display Services .... but it could not be found.

Any help would be greatly appreciated because I was searching for last week .... Thanks!

EDIT: It is easy to change the size of the window because this applescript bridge is a developer behind the i-snap or some other Mac App Store clone?

I am the developer behind the irrigation, and as long as I try to maintain "abundance mentality" I am troubled by the Mac App Store, which is basically "enough for everyone", the entry in this market has produced half-back rivals.

I would be thrilled to see some real innovation around my work, and not just clone in search of a quick money.

Anyway, you want to see the Accessibility API. This is a Carbon C API; This is probably your best reference:
