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. -// -// References: -// <http://crbug.com/27493> -// <rdar://problem/7604051> (<http://openradar.appspot.com/7604051>) - -@interface TCMVisibleView : NSView - -@end - -@implementation TCMVisibleView - -- (struct CGRect)_focusRingVisibleRect -{ - return CGRectZero; -} - -- (id)_focusRingClipAncestor -{ - return self; -} - -@end - -@interface NSView (TCMInterposing) -+ (NSView *)TCMInterposing_focusView; -@end - -namespace FocusIndicationFix { - -bool currentOSHasSetFocusRingStyleInBitmapBug() -{ - UInt32 pixel = 0; - UInt32* pixelPlane = &pixel; - UInt32** pixelPlanes = &pixelPlane; - NSBitmapImageRep *bitmap = [[NSBitmapImageRep alloc] initWithBitmapDataPlanes:(UInt8**)pixelPlanes - pixelsWide:1 - pixelsHigh:1 - bitsPerSample:8 - samplesPerPixel:4 - hasAlpha:YES - isPlanar:NO - colorSpaceName:NSCalibratedRGBColorSpace - bitmapFormat:NSAlphaFirstBitmapFormat - bytesPerRow:4 - bitsPerPixel:32]; - [NSGraphicsContext saveGraphicsState]; - [NSGraphicsContext setCurrentContext:[NSGraphicsContext graphicsContextWithBitmapImageRep:bitmap]]; - NSSetFocusRingStyle(NSFocusRingOnly); - NSRectFill(NSMakeRect(0, 0, 1, 1)); - [NSGraphicsContext restoreGraphicsState]; - [bitmap release]; - - return !pixel; -} - -bool swizzleFocusView() -{ - if (!currentOSHasSetFocusRingStyleInBitmapBug()) - return false; - - Class nsview = [NSView class]; - Method m1 = class_getClassMethod(nsview, @selector(focusView)); - Method m2 = class_getClassMethod(nsview, @selector(TCMInterposing_focusView)); - if (m1 && m2) { - method_exchangeImplementations(m1, m2); - return true; - } - - return false; -} - -static bool interpose = false; - -// A class to restrict the amount of time spent messing with interposing.
