+\headerfile <QxtPimpl>
+\title The Qxt private implementation
+\inmodule QxtCore
+
+\brief The <QxtPimpl> header provides tools for hiding
+details of a class.
+
+Application code generally doesn't have to be concerned about hiding its
+implementation details, but when writing library code it is important to
+maintain a constant interface, both source and binary. Maintaining a constant
+source interface is easy enough, but keeping the binary interface constant
+means moving implementation details into a private class. The PIMPL, or
+d-pointer, idiom is a common method of implementing this separation. QxtPimpl
+offers a convenient way to connect the public and private sides of your class.
+
+\section1 Getting Started
+Before you declare the public class, you need to make a forward declaration
+of the private class. The private class must have the same name as the public
+class, followed by the word Private. For example, a class named MyTest would
+declare the private class with:
+\code
+class MyTestPrivate;
+\endcode
+
+\section1 The Public Class
+Generally, you shouldn't keep any data members in the public class without a
+good reason. Functions that are part of the public interface should be declared
+in the public class, and functions that need to be available to subclasses (for
+calling or overriding) should be in the protected section of the public class.
+To connect the private class to the public class, include the
+QXT_DECLARE_PRIVATE macro in the private section of the public class. In the
+example above, the private class is connected as follows:
+\code
+private:
+    QXT_DECLARE_PRIVATE(MyTest)
+\endcode
+
+Additionally, you must include the QXT_INIT_PRIVATE macro in the public class's
+constructor. Continuing with the MyTest example, your constructor might look
+like this:
+\code
+MyTest::MyTest() {
+    // initialization
+    QXT_INIT_PRIVATE(MyTest);
+}
+\endcode
+
+\section1 The Private Class
+As mentioned above, data members should usually be kept in the private class.
+This allows the memory layout of the private class to change without breaking
+binary compatibility for the public class. Functions that exist only as
+implementation details, or functions that need access to private data members,
+should be implemented here.
+
+To define the private class, inherit from the template QxtPrivate class, and
+include the QXT_DECLARE_PUBLIC macro in its public section. The template
+parameter should be the name of the public class. For example:
+\code
+class MyTestPrivate : public QxtPrivate<MyTest> {
+public:
+    MyTestPrivate();
+    QXT_DECLARE_PUBLIC(MyTest)
+};
+\endcode
+
+\section1 Accessing Private Members
+Use the qxt_d() function (actually a function-like object) from functions in
+the public class to access the private class. Similarly, functions in the
+private class can invoke functions in the public class by using the qxt_p()
+function (this one's actually a function).
+
+For example, assume that MyTest has methods named getFoobar and doBaz(),
+and MyTestPrivate has a member named foobar and a method named doQuux().
+The code might resemble this example:
+\code
+int MyTest::getFoobar() {
+    return qxt_d().foobar;
+}
+
+void MyTestPrivate::doQuux() {
+    qxt_p().doBaz(foobar);
+}
+\endcode

+    \code
+    QxtGlobalShortcut* shortcut = new QxtGlobalShortcut(window);
+    connect(shortcut, SIGNAL(activated()), window, SLOT(toggleVisibility()));
+    shortcut->setShortcut(QKeySequence("Ctrl+Shift+F12"));

+    \class QxtWindowSystem
+    \inmodule QxtWidgets
+    \brief The QxtWindowSystem class provides means for accessing native windows.
+
+    \bold {Note:} The underlying window system might or might not allow one to alter
+    states of windows belonging to other processes.
+
+    \warning QxtWindowSystem is portable in principle, but be careful while
+    using it since you are probably about to do something non-portable.
+
+    \section1 Advanced example usage:
+    \code
+    class NativeWindow : public QWidget {
+        public:
+            NativeWindow(WId wid) {
+                QWidget::create(wid, false, false); // window, initializeWindow, destroyOldWindow
+            }
+            ~NativeWindow() {
+                QWidget::destroy(false, false); // destroyWindow, destroySubWindows
+            }
+    };
+    \endcode
+
+    \code
+    WindowList windows = QxtWindowSystem::windows();
+    QStringList titles = QxtWindowSystem::windowTitles();
+    bool ok = false;
+    QString title = QInputDialog::getItem(0, "Choose Window", "Choose a window to be hid:", titles, 0, false, &ok);
+    if (ok)
+    {
+        int index = titles.indexOf(title);
+        if (index != -1)
+        {
+            NativeWindow window(windows.at(index));
+            window.hide();
+        }
+    }
+    \endcode
+
+    \bold {Note:} Currently supported platforms are \bold X11 and \bold Windows.
