Done.

+// A view class that implements a bubble consisting of the following items:

+// * one title text ("title")
+// * one message text ("message")
+// * one optional link ("link")
+// * two optional buttons ("ok" and "cancel")

It has a close button too?

[Hironori Bono, 2011/12/09 11:14:32]

As written below, I have removed the close button on Mac. Thanks for your
comment.

+//
+// This bubble is convenient when we wish to ask transient, non-blocking
+// questions. Unlike a dialog, a bubble menu disappears when we click outside of
+// its window to avoid blocking user operations. A bubble is laid out as
+// follows:
+//
+//   +------------------------+
+//   | icon title           x |

It's  a little odd to have the close button on the right on Mac. Is it even
necessary with the buttons below?

[Hironori Bono, 2011/12/09 11:14:32]

Thanks for noticing it. This change straightforwardly implemented the Windows
code and it indeed looks weird on Mac. After talking with some people, I have
removed this button on Mac.

+//   | message                |
+//   | link                   |
+//   |          [OK] [Cancel] |

Normal Mac button ordering in dialogs is to put the “proceed” action (like “OK”)
all the way on the right.

Done.
