+    \class TQWorkspace qworkspace.h
+    \brief The TQWorkspace widget provides a workspace window that can
+    contain decorated windows, e.g. for MDI.
+
+    \module workspace
+
+    \ingroup application
+    \ingroup organizers
+    \mainclass
+
+    MDI (multiple document interface) applications typically have one
+    main window with a menu bar and toolbar, and a central widget that
+    is a TQWorkspace. The workspace itself contains zero, one or more
+    document windows, each of which is a widget.
+
+    The workspace itself is an ordinary TQt widget. It has a standard
+    constructor that takes a parent widget and an object name. The
+    parent window is usually a TQMainWindow, but it need not be.
+
+    Document windows (i.e. MDI windows) are also ordinary TQt widgets
+    which have the workspace as their parent widget. When you call
+    show(), hide(), showMaximized(), setCaption(), etc. on a document
+    window, it is shown, hidden, etc. with a frame, caption, icon and
+    icon text, just as you'd expect. You can provide widget flags
+    which will be used for the layout of the decoration or the
+    behaviour of the widget itself.
+
+    To change or retrieve the geometry of MDI windows you must operate
+    on the MDI widget's parentWidget(). (The parentWidget() provides
+    access to the decorated window in which the MDI window's widget is
+    shown.)
+
+    A document window becomes active when it gets the keyboard focus.
+    You can also activate a window in code using setFocus(). The user
+    can activate a window by moving focus in the usual ways, for
+    example by clicking a window or by pressing Tab. The workspace
+    emits a signal windowActivated() when it detects the activation
+    change, and the function activeWindow() always returns a pointer
+    to the active document window.
+
+    The convenience function windowList() returns a list of all
+    document windows. This is useful to create a popup menu
+    "<u>W</u>indows" on the fly, for example.
+
+    TQWorkspace provides two built-in layout strategies for child
+    windows: cascade() and tile(). Both are slots so you can easily
+    connect menu entries to them.
+
+    If you want your users to be able to work with document windows
+    larger than the actual workspace, set the scrollBarsEnabled
+    property to TRUE.
+
+    If the top-level window contains a menu bar and a document window
+    is maximised, TQWorkspace moves the document window's minimize,
+    restore and close buttons from the document window's frame to the
+    workspace window's menu bar. It then inserts a window operations
+    menu at the far left of the menu bar.
