    While Qt offers a lot of classes for writing your application, Apple's
-    Cocoa framework offers lots of functionality that is not currently in Qt or
-    may never end up in Qt. Using QMacCocoaViewContainer, it is possible to put an
-    arbitrary NSView-derived class from Cocoa and put it in a Qt hierarchy.
-    Depending on how comfortable you are with using objective-C, you can use
-    QMacCocoaViewContainer directly, or subclass it to wrap further functionality
-    of the underlying NSView.
+    Cocoa frameworks offer functionality that is not currently available (or
+    may never end up) in Qt. Using QMacCocoaViewContainer, it is possible to take an
+    arbitrary NSView-derived class from Cocoa and put it in a Qt widgets hierarchy.
+    Depending on the level of integration you need, you can use QMacCocoaViewContainer
+    directly or subclass it to wrap more functionality of the underlying NSView.

-    QMacCocoaViewContainer works regardless if Qt is built against Carbon or
-    Cocoa. However, QCocoaContainerView requires \macos 10.5 or better to be
-    used with Carbon.
+    It should be also noted that, at the Cocoa level, there is a difference
+    between top-level windows and views (widgets that are inside a window).
+    For this reason, make sure that the NSView that you are wrapping doesn't
+    end up as a top-level window. The best way to ensure this is to make sure
+    QMacCocoaViewContainer's parent widget is not null.

-    It should be also noted that at the low level on \macos, there is a
-    difference between windows (top-levels) and view (widgets that are inside a
-    window). For this reason, make sure that the NSView that you are wrapping
-    doesn't end up as a top-level. The best way to ensure this is to make sure
-    you always have a parent and not set the parent to 0.
-
-    If you are using QMacCocoaViewContainer as a sub-class and are mixing and
-    matching objective-C with C++ (a.k.a. objective-C++). It is probably
-    simpler to have your file end with \tt{.mm} than \tt{.cpp}. Most Apple tools will
-    correctly identify the source as objective-C++.
