DESCRIPTION
       The QWorkspace widget provides a workspace window that can contain decorated windows, e.g.
       for MDI.

       MDI (multiple document interface) applications typically have one main window with a menu
       bar and toolbar, and a central widget that is a QWorkspace. The workspace itself contains
       zero, one or more document windows, each of which is a widget.

       The workspace itself is an ordinary Qt widget. It has a standard constructor that takes a
       parent widget and an object name. The parent window is usually a QMainWindow, but it need
       not be.

       Document windows (i.e. MDI windows) are also ordinary Qt 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.

       QWorkspace 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, QWorkspace
       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.

       See also Main Window and Related Classes and Organizers.

   Member Type Documentation
QWorkspace::WindowOrder
       Specifies the order in which windows are returned from windowList().

       QWorkspace::CreationOrder - The windows are returned in the order of their creation

       QWorkspace::StackingOrder - The windows are returned in the order of their stacking

MEMBER FUNCTION DOCUMENTATION
QWorkspace::QWorkspace ( QWidget * parent = 0, const char * name = 0 )
       Constructs a workspace with a parent and a name.

QWorkspace::~QWorkspace ()
       Destroys the workspace and frees any allocated resources.

void QWorkspace::activateNextWindow () [slot]
       Activates the next window in the child window chain.

       See also activatePrevWindow().

void QWorkspace::activatePrevWindow () [slot]
       Activates the previous window in the child window chain.

       See also activateNextWindow().

QWidget * QWorkspace::activeWindow () const
       Returns the active window, or 0 if no window is active.

       Example: mdi/application.cpp.

void QWorkspace::cascade () [slot]
       Arranges all the child windows in a cascade pattern.

       See also tile().

       Example: mdi/application.cpp.

void QWorkspace::closeActiveWindow () [slot]
       Closes the child window that is currently active.

       See also closeAllWindows().

void QWorkspace::closeAllWindows () [slot]
       Closes all child windows.

       The windows are closed in random order. The operation stops if a window does not accept
       the close event.

       See also closeActiveWindow().

bool QWorkspace::scrollBarsEnabled () const
       Returns TRUE if the workspace provides scrollbars; otherwise returns FALSE. See the
       "scrollBarsEnabled" property for details.

void QWorkspace::setScrollBarsEnabled ( bool enable )
       Sets whether the workspace provides scrollbars to enable. See the "scrollBarsEnabled"
       property for details.

void QWorkspace::tile () [slot]
       Arranges all child windows in a tile pattern.

       See also cascade().

       Example: mdi/application.cpp.

void QWorkspace::windowActivated ( QWidget * w ) [signal]
       This signal is emitted when the window widget w becomes active. Note that w can be null,
       and that more than one signal may be emitted for a single activation event.

       See also activeWindow() and windowList().

QWidgetList QWorkspace::windowList ( WindowOrder order ) const
       Returns a list of all windows. If order is CreationOrder (the default) the windows are
       listed in the order in which they had been inserted into the workspace. If order is
       StackingOrder the windows are listed in their stacking order, with the topmost window
       being the last window in the list.

       QWidgetList is the same as QPtrList<QWidget>.

       See also QPtrList.

       Example: mdi/application.cpp.

QWidgetList QWorkspace::windowList () const
       This function is obsolete. It is provided to keep old source working. We strongly advise
       against using it in new code.

       This is an overloaded member function, provided for convenience. It behaves essentially
       like the above function.

   Property Documentation
bool scrollBarsEnabled
       This property holds whether the workspace provides scrollbars.

       If this property is set to TRUE, it is possible to resize child windows over the right or
       the bottom edge out of the visible area of the workspace. The workspace shows scrollbars
       to make it possible for the user to access those windows. If this property is set to FALSE
       (the default), resizing windows out of the visible area of the workspace is not permitted.

       Set this property's value with setScrollBarsEnabled() and get this property's value with
       scrollBarsEnabled().
