// This file (and its associated .h file) is a clone of ThemeMac.mm.
// Because the original file is designed to run in-process inside a Cocoa view,
// we must maintain a fork. Please maintain this file by performing parallel
// changes to it.
//
// The only changes from ThemeMac should be:
// - The classname change from ThemeMac to ThemeChromiumMac.
// - The import of FlippedView() and its use as the parent view for cell
// rendering.
// - In updateStates() the code to update the cells' inactive state.
// - In paintButton() the code to save/restore the window's default button cell.
// - The Snow Leopard focus ring bug fix and its use around every call to
// -[NSButtonCell drawWithFrame:inView:].
//
// For all other differences, if it was introduced in this file, then the
// maintainer forgot to include it in the list; otherwise it is an update that
// should have been applied to this file but was not.
// FIXME: Default buttons really should be more like push buttons and not like buttons.
// --- START fix for Snow Leopard focus ring bug ---
// There is a bug in the Cocoa focus ring drawing code. The code calls +[NSView
// focusView] (to get the currently focused view) and then calls an NSRect-
// returning method on that view to obtain a clipping rect. However, if there is
// no focused view (as there won't be if the destination is a context), the rect
// returned from the method invocation on nil is garbage.
//
// The garbage fortunately does not clip the focus ring on Leopard, but
// unfortunately does so on Snow Leopard. Therefore, if a runtime test shows
// that focus ring drawing fails, we swizzle NSView to ensure it returns a valid
// view with a valid clipping rectangle.
//
// FIXME: After the referenced bug is fixed on all supported platforms, remove
// this code.
//
