Comment #9 on issue 13515 by viettrungluu: Dragging a window by grabbing
the bottom edge of the titlebar after ripping off a tab does not work
http://code.google.com/p/chromium/issues/detail?id=13515
It may be an Apple bug in animating |-setFrame:|. Replacing
the "[frameTarget setFrame:tabFrame];" line with
the following either fixes this bug or makes it extremely hard to reproduce
(i.e., I haven't managed to) --
unfortunately, it also makes animation look a bit wonky:
if (!oldTargetValue ||
!NSEqualPoints([oldTargetValue rectValue].origin,
tabFrame.origin))
[frameTarget setFrameOrigin:tabFrame.origin];
if (!oldTargetValue ||
!NSEqualSizes([oldTargetValue rectValue].size, tabFrame.size))
[frameTarget setFrameSize:tabFrame.size];
On the other hand, replacing it with the following merely makes it hard to
reproduce (I have, with some effort)
-- since you need a bad case when |-setFrame:| is called:
if (oldTargetValue &&
NSEqualSizes([oldTargetValue rectValue].size, tabFrame.size))
[frameTarget setFrameOrigin:tabFrame.origin];
else if (oldTargetValue &&
NSEqualPoints([oldTargetValue rectValue].origin,
tabFrame.origin))
[frameTarget setFrameSize:tabFrame.size];
else
[frameTarget setFrame:tabFrame];
Maybe I'll have to come up with a test app which isolates the problem.
