11// WindowSizeAutosaver is a helper class that makes it easy to let windows
12// autoremember their position or position and size in a PrefService object.
13// To use this, add a |base::scoped_nsobject<WindowSizeAutosaver>| to your
14// window
15// controller and initialize it in the window controller's init method, passing
16// a window and an autosave name. The autosaver will register for "window moved"
17// and "window resized" notifications and write the current window state to the
18// prefs service every time they fire. The window's size is automatically
19// restored when the autosaver's |initWithWindow:...| method is called.
20//
21// Note: Your xib file should have "Visible at launch" UNCHECKED, so that the
22// initial repositioning is not visible.
