DESCRIPTION
       The QMainWindow class provides a main application window, with a menu
       bar, dock windows (e.g. for toolbars), and a status bar.

       Main windows are most often used to provide menus, toolbars and a
       status bar around a large central widget, such as a text edit, drawing
       canvas or QWorkspace (for MDI applications). QMainWindow is usually
       subclassed since this makes it easier to encapsulate the central
       widget, menus and toolbars as well as the window's state. Subclassing
       makes it possible to create the slots that are called when the user
       clicks menu items or toolbar buttons. You can also create main windows
       using Qt Designer. We'll briefly review adding menu items and toolbar
       buttons then describe the facilities of QMainWindow itself.

	   QMainWindow *mw = new QMainWindow;
	   QTextEdit *edit = new QTextEdit( mw, "editor" );
	   edit->setFocus();
	   mw->setCaption( "Main Window" );
	   mw->setCentralWidget( edit );
	   mw->show();

       QMainWindows may be created in their own right as shown above. The
       central widget is set with setCentralWidget(). Popup menus can be added
       to the default menu bar, widgets can be added to the status bar,
       toolbars and dock windows can be added to any of the dock areas.

	       ApplicationWindow *mw = new ApplicationWindow();
	       mw->setCaption( "Qt Example - Application" );
	       mw->show();

       In the extract above ApplicationWindow is a subclass of QMainWindow
       that we must write for ourselves; this is the usual approach to using
       QMainWindow. (The source for the extracts in this description are taken
       from application/main.cpp, application/application.cpp,
       action/main.cpp, and action/application.cpp )

       When subclassing we add the menu items and toolbars in the subclass's
       constructor. If we've created a QMainWindow instance directly we can
       add menu items and toolbars just as easily by passing the QMainWindow
       instance as the parent instead of the this pointer.

	       QPopupMenu * help = new QPopupMenu( this );
	       menuBar()->insertItem( "&Help", help );
	       help->insertItem( "&About", this, SLOT(about()), Key_F1 );

       Here we've added a new menu with one menu item. The menu has been
       inserted into the menu bar that QMainWindow provides by default and
       which is accessible through the menuBar() function. The slot will be
       called when the menu item is clicked.

	       QToolBar * fileTools = new QToolBar( this, "file operations" );
	       fileTools->setLabel( "File Operations" );

	       QToolButton * fileOpen
		   = new QToolButton( openIcon, "Open File", QString::null,
				      this, SLOT(choose()), fileTools, "open file" );

       This extract shows the creation of a toolbar with one toolbar button.
       QMainWindow supplies four dock areas for toolbars. When a toolbar is
       created as a child of a QMainWindow (or derived class) instance it will
       be placed in a dock area (the Top dock area by default). The slot will
       be called when the toolbar button is clicked. Any dock window can be
       added to a dock area either using addDockWindow(), or by creating a
       dock window with the QMainWindow as the parent.

	       e = new QTextEdit( this, "editor" );
	       e->setFocus();
	       setCentralWidget( e );
	       statusBar()->message( "Ready", 2000 );

       Having created the menus and toolbar we create an instance of the large
       central widget, give it the focus and set it as the main window's
       central widget. In the example we've also set the status bar, accessed
       via the statusBar() function, to an initial message which will be
       displayed for two seconds. Note that you can add additional widgets to
       the status bar, for example labels, to show further status information.
       See the QStatusBar documentation for details, particularly the
       addWidget() function.

       Often we want to synchronize a toolbar button with a menu item. For
       example, if the user clicks a 'bold' toolbar button we want the 'bold'
       menu item to be checked. This synchronization can be achieved
       automatically by creating actions and adding the actions to the toolbar
       and menu.

	       QAction * fileOpenAction;

	       fileOpenAction = new QAction( QPixmap( fileopen ), "&Open...",
					     CTRL+Key_O, this, "open" );
	       connect( fileOpenAction, SIGNAL( activated() ) , this, SLOT( choose() ) );

       Here we create an action with an icon which will be used in any menu
       and toolbar that the action is added to. We've also given the action a
       menu name, '&Open', and a keyboard shortcut. The connection that we
       have made will be used when the user clicks either the menu item or the
       toolbar button.

	       QPopupMenu * file = new QPopupMenu( this );
	       menuBar()->insertItem( "&File", file );

	       fileOpenAction->addTo( file );

       The extract above shows the creation of a popup menu. We add the menu
       to the QMainWindow's menu bar and add our action.

	       QToolBar * fileTools = new QToolBar( this, "file operations" );
	       fileTools->setLabel( "File Operations" );
	       fileOpenAction->addTo( fileTools );

       Here we create a new toolbar as a child of the QMainWindow and add our
       action to the toolbar.

       We'll now explore the functionality offered by QMainWindow.

       The main window will take care of the dock areas, and the geometry of
       the central widget, but all other aspects of the central widget are
       left to you. QMainWindow automatically detects the creation of a menu
       bar or status bar if you specify the QMainWindow as parent, or you can
       use the provided menuBar() and statusBar() functions. The functions
       menuBar() and statusBar() create a suitable widget if one doesn't
       exist, and update the window's layout to make space.

       QMainWindow provides a QToolTipGroup connected to the status bar. The
       function toolTipGroup() provides access to the default QToolTipGroup.
       It isn't possible to set a different tool tip group.

       New dock windows and toolbars can be added to a QMainWindow using
       addDockWindow(). Dock windows can be moved using moveDockWindow() and
       removed with removeDockWindow(). QMainWindow allows default dock window
       (toolbar) docking in all its dock areas (Top, Left, Right, Bottom). You
       can use setDockEnabled() to enable and disable docking areas for dock
       windows. When adding or moving dock windows you can specify their
       'edge' (dock area). The currently available edges are: Top, Left,
       Right, Bottom, Minimized (effectively a 'hidden' dock area) and TornOff
       (floating). See Qt::Dock for an explanation of these areas. Note that
       the *ToolBar functions are included for backward compatibility; all new
       code should use the *DockWindow functions. QToolbar is a subclass of
       QDockWindow so all functions that work with dock windows work on
       toolbars in the same way.

       If the user clicks the close button, then the dock window is hidden. A
       dock window can be hidden or unhidden by the user by right clicking a
       dock area and clicking the name of the relevant dock window on the pop
       up dock window menu. This menu lists the names of every dock window;
       visible dock windows have a tick beside their names. The dock window
       menu is created automatically as required by createDockWindowMenu().
       Since it may not always be appropriate for a dock window to appear on
       this menu the setAppropriate() function is used to inform the main
       window whether or not the dock window menu should include a particular
       dock window. Double clicking a dock window handle (usually on the left-
       hand side of the dock window) undocks (floats) the dock window. Double
       clicking a floating dock window's titlebar will dock the floating dock
       window. (See also QMainWindow::DockWindows.)

       Some functions change the appearance of a QMainWindow globally:

       QDockWindow::setHorizontalStretchable() and
       QDockWindow::setVerticalStretchable() are used to make specific dock
       windows or toolbars stretchable.

       setUsesBigPixmaps() is used to set whether tool buttons should draw
       small or large pixmaps (see QIconSet for more information).

       setUsesTextLabel() is used to set whether tool buttons should display a
       textual label in addition to pixmaps (see QToolButton for more
       information).

       The user can drag dock windows into any enabled docking area. Dock
       windows can also be dragged within a docking area, for example to
       rearrange the order of some toolbars. Dock windows can also be dragged
       outside any docking area (undocked or 'floated'). Being able to drag
       dock windows can be enabled (the default) and disabled using
       setDockWindowsMovable().

       The Minimized edge is a hidden dock area. If this dock area is enabled
       the user can hide (minimize) a dock window or show (restore) a
       minimized dock window by clicking the dock window handle. If the user
       hovers the mouse cursor over one of the handles, the caption of the
       dock window is displayed in a tool tip (see QDockWindow::caption() or
       QToolBar::label()), so if you enable the Minimized dock area, it is
       best to specify a meaningful caption or label for each dock window. To
       minimize a dock window programmatically use moveDockWindow() with an
       edge of Minimized.

       Dock windows are moved transparently by default, i.e. during the drag
       an outline rectangle is drawn on the screen representing the position
       of the dock window as it moves. If you want the dock window to be shown
       normally whilst it is moved use setOpaqueMoving().

       The location of a dock window, i.e. its dock area and position within
       the dock area, can be determined by calling getLocation(). Movable dock
       windows can be lined up to minimize wasted space with
       lineUpDockWindows(). Pointers to the dock areas are available from
       topDock(), leftDock(), rightDock() and bottomDock(). A customize menu
       item is added to the pop up dock window menu if isCustomizable()
       returns TRUE; it returns FALSE by default. Reimplement isCustomizable()
       and customize() if you want to offer this extra menu item, for example,
       to allow the user to change settings relating to the main window and
       its toolbars and dock windows.

       The main window's menu bar is fixed (at the top) by default. If you
       want a movable menu bar, create a QMenuBar as a stretchable widget
       inside its own movable dock window and restrict this dock window to
       only live within the Top or Bottom dock:

	   QToolBar *tb = new QToolBar( this );
	   addDockWindow( tb, tr( "Menubar" ), Top, FALSE );
	   QMenuBar *mb = new QMenuBar( tb );
	   mb->setFrameStyle( QFrame::NoFrame );
	   tb->setStretchableWidget( mb );
	   setDockEnabled( tb, Left, FALSE );
	   setDockEnabled( tb, Right, FALSE );

       An application with multiple dock windows can choose to save the
       current dock window layout in order to restore it later, e.g. in the
       next session. You can do this by using the streaming operators for
       QMainWindow.

       To save the layout and positions of all the dock windows do this:

	   QFile file( filename );
	   if ( file.open( IO_WriteOnly ) ) {
	       QTextStream stream( &file );
	       stream << *mainWindow;
	       file.close();
	   }

       To restore the dock window positions and sizes (normally when the
       application is next started), do following:

	   QFile file( filename );
	   if ( file.open( IO_ReadOnly ) ) {
	       QTextStream stream( &file );
	       stream >> *mainWindow;
	       file.close();
	   }

       The QSettings class can be used in conjunction with the streaming
       operators to store the application's settings.

       QMainWindow's management of dock windows and toolbars is done
       transparently behind-the-scenes by QDockArea.

       For multi-document interfaces (MDI), use a QWorkspace as the central
       widget.

       Adding dock windows, e.g. toolbars, to QMainWindow's dock areas is
       straightforward. If the supplied dock areas are not sufficient for your
       application we suggest that you create a QWidget subclass and add your
       own dock areas (see QDockArea) to the subclass since QMainWindow
       provides functionality specific to the standard dock areas it provides.

   Member Type Documentation
QMainWindow::DockWindows
       Right-clicking a dock area will pop-up the dock window menu
       (createDockWindowMenu() is called automatically). When called in code
       you can specify what items should appear on the menu with this enum.

       QMainWindow::OnlyToolBars - The menu will list all the toolbars, but
       not any other dock windows.

       QMainWindow::NoToolBars - The menu will list dock windows but not
       toolbars.

       QMainWindow::AllDockWindows - The menu will list all toolbars and other
       dock windows. (This is the default.)

MEMBER FUNCTION DOCUMENTATION
QMainWindow::QMainWindow ( QWidget * parent = 0, const char * name = 0, WFlags
       f = WType_TopLevel )
       Constructs an empty main window. The parent, name and widget flags f,
       are passed on to the QWidget constructor.

       By default, the widget flags are set to WType_TopLevel rather than 0 as
       they are with QWidget. If you don't want your QMainWindow to be a top
       level widget then you will need to set f to 0.

QMainWindow::~QMainWindow ()
       Destroys the object and frees any allocated resources.

void QMainWindow::addDockWindow ( QDockWindow * dockWindow, Dock edge =
       DockTop, bool newLine = FALSE ) [virtual]
       Adds dockWindow to the edge dock area.

       If newLine is FALSE (the default) then the dockWindow is added at the
       end of the edge. For vertical edges the end is at the bottom, for
       horizontal edges (including Minimized) the end is at the right. If
       newLine is TRUE a new line of dock windows is started with dockWindow
       as the first (left-most and top-most) dock window.

       If dockWindow is managed by another main window, it is first removed
       from that window.

void QMainWindow::addDockWindow ( QDockWindow * dockWindow, const QString &
       label, Dock edge = DockTop, bool newLine = FALSE ) [virtual]
       This is an overloaded member function, provided for convenience. It
       behaves essentially like the above function.

       Adds dockWindow to the dock area with label label.

       If newLine is FALSE (the default) the dockWindow is added at the end of
       the edge. For vertical edges the end is at the bottom, for horizontal
       edges (including Minimized) the end is at the right. If newLine is TRUE
       a new line of dock windows is started with dockWindow as the first
       (left-most and top-most) dock window.

       If dockWindow is managed by another main window, it is first removed
       from that window.

void QMainWindow::addToolBar ( QDockWindow *, Dock = DockTop, bool newLine =
       FALSE )
       This function is obsolete. It is provided to keep old source working.
       We strongly advise against using it in new code.

void QMainWindow::addToolBar ( QDockWindow *, const QString & label, Dock =
       DockTop, bool newLine = FALSE )
       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.

bool QMainWindow::appropriate ( QDockWindow * dw ) const
       Returns TRUE if it is appropriate to include a menu item for the dw
       dock window in the dock window menu; otherwise returns FALSE.

       The user is able to change the state (show or hide) a dock window that
       has a menu item by clicking the item.

       Call setAppropriate() to indicate whether or not a particular dock
       window should appear on the popup menu.

       See also setAppropriate().

QDockArea * QMainWindow::bottomDock () const
       Returns a pointer the Bottom dock area

       See also topDock(), leftDock(), and rightDock().

QWidget * QMainWindow::centralWidget () const
       Returns a pointer to the main window's central widget.

       The central widget is surrounded by the left, top, right and bottom
       dock areas. The menu bar is above the top dock area.

       See also setCentralWidget().

       Example: qfd/qfd.cpp.

void QMainWindow::childEvent ( QChildEvent * e ) [virtual protected]
       Monitors events, recieved in e, to ensure the layout is updated.

       Reimplemented from QObject.

QPopupMenu * QMainWindow::createDockWindowMenu ( DockWindows dockWindows =
       AllDockWindows ) const
       Creates the dock window menu which contains all toolbars (if
       dockWindows is OnlyToolBars ), all dock windows (if dockWindows is
       NoToolBars) or all toolbars and dock windows (if dockWindows is
       AllDockWindows - the default).

       This function is called internally when necessary, e.g. when the user
       right clicks a dock area (providing isDockMenuEnabled() returns TRUE).

       The menu items representing the toolbars and dock windows are
       checkable. The visible dock windows are checked and the hidden dock
       windows are unchecked. The user can click a menu item to change its
       state (show or hide the dock window).

       The list and the state are always kept up-to-date.

       Toolbars and dock windows which are not appropriate in the current
       context (see setAppropriate()) are not listed in the menu.

       The menu also has a menu item for lining up the dock windows.

       If isCustomizable() returns TRUE, a Customize menu item is added to the
       menu, which if clicked will call customize(). The isCustomizable()
       function we provide returns FALSE and customize() does nothing, so they
       must be reimplemented in a subclass to be useful.

void QMainWindow::customize () [virtual slot]
       This function is called when the user clicks the Customize menu item on
       the dock window menu.

       The customize menu item will only appear if isCustomizable() returns
       TRUE (it returns FALSE by default).

       The function is intended, for example, to provide the user with a means
       of telling the application that they wish to customize the main window,
       dock windows or dock areas.

       The default implementation does nothing and the Customize menu item is
       not shown on the right-click menu by default. If you want the item to
       appear then reimplement isCustomizable() to return TRUE, and
       reimplement this function to do whatever you want.

       See also isCustomizable().

void QMainWindow::dockWindowPositionChanged ( QDockWindow * dockWindow )
       [signal]
       This signal is emitted when the dockWindow has changed its position. A
       change in position occurs when a dock window is moved within its dock
       area or moved to another dock area (including the Minimized and TearOff
       dock areas).

       See also getLocation().

QPtrList<;QDockWindow> QMainWindow::dockWindows ( Dock dock ) const
       Returns a list of all the dock windows which are in the dock dock area,
       regardless of their state.

       For example, the DockTornOff dock area may contain closed dock windows
       but these are returned along with the visible dock windows.

QPtrList<;QDockWindow> QMainWindow::dockWindows () const
       This is an overloaded member function, provided for convenience. It
       behaves essentially like the above function.

       Returns the list of dock windows which belong to this main window,
       regardless of which dock area they are in or what their state is, (e.g.
       irrespective of whether they are visible or not).

bool QMainWindow::dockWindowsMovable () const
       Returns TRUE if the dock windows are movable; otherwise returns FALSE.
       See the "dockWindowsMovable" property for details.

bool QMainWindow::getLocation ( QDockWindow * dw, Dock & dock, int & index,
       bool & nl, int & extraOffset ) const
       Finds the location of the dock window dw.

       If the dw dock window is found in the main window the function returns
       TRUE and populates the dock variable with the dw's dock area and the
       index with the dw's position within the dock area. It also sets nl to
       TRUE if the dw begins a new line (otherwise FALSE), and extraOffset
       with the dock window's offset.

       If the dw dock window is not found then the function returns FALSE and
       the state of dock, index, nl and extraOffset is undefined.

       If you want to save and restore dock window positions then use
       operator>>() and operator<<().

       See also operator>>() and operator<<().

bool QMainWindow::hasDockWindow ( QDockWindow * dw )
       Returns TRUE if dw is a dock window known to the main window; otherwise
       returns FALSE.

bool QMainWindow::isCustomizable () const [virtual]
       Returns TRUE if the dock area dock window menu includes the Customize
       menu item (which calls customize() when clicked). Returns FALSE by
       default, i.e. the popup menu will not contain a Customize menu item.
       You will need to reimplement this function and set it to return TRUE if
       you wish the user to be able to see the dock window menu.

       See also customize().

bool QMainWindow::isDockEnabled ( Dock dock ) const
       Returns TRUE if the dock dock area is enabled, i.e. it can accept user
       dragged dock windows; otherwise returns FALSE.

       See also setDockEnabled().

bool QMainWindow::isDockEnabled ( QDockArea * area ) const
       This is an overloaded member function, provided for convenience. It
       behaves essentially like the above function.

       Returns TRUE if dock area area is enabled, i.e. it can accept user
       dragged dock windows; otherwise returns FALSE.

       See also setDockEnabled().

bool QMainWindow::isDockEnabled ( QDockWindow * tb, Dock dock ) const
       This is an overloaded member function, provided for convenience. It
       behaves essentially like the above function.

       Returns TRUE if dock area dock is enabled for the dock window tb;
       otherwise returns FALSE.

       See also setDockEnabled().

bool QMainWindow::isDockEnabled ( QDockWindow * dw, QDockArea * area ) const
       This is an overloaded member function, provided for convenience. It
       behaves essentially like the above function.

       Returns TRUE if dock area area is enabled for the dock window dw;
       otherwise returns FALSE.

       See also setDockEnabled().

bool QMainWindow::isDockMenuEnabled () const
       Returns TRUE, if the dock window menu is enabled; otherwise returns
       FALSE.

       The menu lists the (appropriate()) dock windows (which may be shown or
       hidden), and has a "Line Up Dock Windows" menu item. It will also have
       a "Customize" menu item if isCustomizable() returns TRUE.

       See also setDockEnabled(), lineUpDockWindows(), appropriate(), and
       setAppropriate().

QDockArea * QMainWindow::leftDock () const
       Returns the Left dock area

       See also rightDock(), topDock(), and bottomDock().

void QMainWindow::lineUpDockWindows ( bool keepNewLines = FALSE )
       This function will line up dock windows within the visible dock areas
       (Top, Left, Right and Bottom) as compactly as possible.

       If keepNewLines is TRUE, all dock windows stay on their original lines.
       If keepNewLines is FALSE then newlines may be removed to achieve the
       most compact layout possible.

       The method only works if dockWindowsMovable() returns TRUE.

void QMainWindow::lineUpToolBars ( bool keepNewLines = FALSE )
       This function is obsolete. It is provided to keep old source working.
       We strongly advise against using it in new code.

void QMainWindow::menuAboutToShow () [protected slot]
       This slot is called from the aboutToShow() signal of the default dock
       menu of the mainwindow. The default implementation initializes the menu
       with all dock windows and toolbars in this slot.

QMenuBar * QMainWindow::menuBar () const
       Returns the menu bar for this window.

       If there isn't one, then menuBar() creates an empty menu bar.

       See also statusBar().

void QMainWindow::moveDockWindow ( QDockWindow * dockWindow, Dock edge =
       DockTop ) [virtual]
       Moves dockWindow to the end of the edge.

       For vertical edges the end is at the bottom, for horizontal edges
       (including Minimized) the end is at the right.

       If dockWindow is managed by another main window, it is first removed
       from that window.

void QMainWindow::moveDockWindow ( QDockWindow * dockWindow, Dock edge, bool
       nl, int index, int extraOffset = -1 ) [virtual]
       This is an overloaded member function, provided for convenience. It
       behaves essentially like the above function.

       Moves dockWindow to position index within the edge dock area.

       Any dock windows with positions index or higher have their position
       number incremented and any of these on the same line are moved right
       (down for vertical dock areas) to make room.

       If nl is TRUE, a new dock window line is created below the line in
       which the moved dock window appears and the moved dock window, with any
       others with higher positions on the same line, is moved to this new
       line.

       The extraOffset is the space to put between the left side of the dock
       area (top side for vertical dock areas) and the dock window. (This is
       mostly used for restoring dock windows to the positions the user has
       dragged them to.)

       If dockWindow is managed by another main window, it is first removed
       from that window.

void QMainWindow::moveToolBar ( QDockWindow *, Dock = DockTop )
       This function is obsolete. It is provided to keep old source working.
       We strongly advise against using it in new code.

void QMainWindow::moveToolBar ( QDockWindow *, Dock, bool nl, int index, int
       extraOffset = -1 )
       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.

bool QMainWindow::opaqueMoving () const
       Returns TRUE if dock windows are moved opaquely; otherwise returns
       FALSE. See the "opaqueMoving" property for details.

void QMainWindow::pixmapSizeChanged ( bool ) [signal]
       This signal is emitted whenever the setUsesBigPixmaps() is called with
       a value different to the current setting. All widgets that should
       respond to such changes, e.g. toolbar buttons, must connect to this
       signal.

void QMainWindow::removeDockWindow ( QDockWindow * dockWindow ) [virtual]
       Removes dockWindow from the main window's docking area, provided
       dockWindow is non-null and managed by this main window.

void QMainWindow::removeToolBar ( QDockWindow * )
       This function is obsolete. It is provided to keep old source working.
       We strongly advise against using it in new code.

QDockArea * QMainWindow::rightDock () const
       Returns the Right dock area

       See also leftDock(), topDock(), and bottomDock().

bool QMainWindow::rightJustification () const
       Returns TRUE if the main window right-justifies its dock windows;
       otherwise returns FALSE. See the "rightJustification" property for
       details.

void QMainWindow::setAppropriate ( QDockWindow * dw, bool a ) [virtual slot]
       Use this function to control whether or not the dw dock window's
       caption should appear as a menu item on the dock window menu that lists
       the dock windows.

       If a is TRUE then the dw will appear as a menu item on the dock window
       menu. The user is able to change the state (show or hide) a dock window
       that has a menu item by clicking the item; depending on the state of
       your application, this may or may not be appropriate. If a is FALSE the
       dw will not appear on the popup menu.

       See also showDockMenu(), isCustomizable(), and customize().

void QMainWindow::setCentralWidget ( QWidget * w ) [virtual]
       Sets the central widget for this main window to w.

       The central widget is surrounded by the left, top, right and bottom
       dock areas. The menu bar is above the top dock area.

       See also centralWidget().

void QMainWindow::setDockEnabled ( Dock dock, bool enable ) [virtual]
       If enable is TRUE then users can dock windows in the dock area. If
       enable is FALSE users cannot dock windows in the dock dock area.

       Users can dock (drag) dock windows into any enabled dock area.

void QMainWindow::setDockEnabled ( QDockWindow * dw, Dock dock, bool enable )
       [virtual]
       This is an overloaded member function, provided for convenience. It
       behaves essentially like the above function.

       If enable is TRUE then users can dock the dw dock window in the dock
       area. If enable is FALSE users cannot dock the dw dock window in the
       dock area.

       In general users can dock (drag) dock windows into any enabled dock
       area. Using this function particular dock areas can be enabled (or
       disabled) as docking points for particular dock windows.

void QMainWindow::setDockMenuEnabled ( bool b ) [virtual slot]
       If b is TRUE, then right clicking on a dock window or dock area will
       pop up the dock window menu. If b is FALSE, right clicking a dock
       window or dock area will not pop up the menu.

       The menu lists the (appropriate()) dock windows (which may be shown or
       hidden), and has a "Line Up Dock Windows" item. It will also have a
       "Customize" menu item if isCustomizable() returns TRUE.

       See also lineUpDockWindows() and isDockMenuEnabled().

void QMainWindow::setDockWindowsMovable ( bool ) [virtual slot]
       Sets whether the dock windows are movable. See the "dockWindowsMovable"
       property for details.

void QMainWindow::setOpaqueMoving ( bool ) [virtual slot]
       Sets whether dock windows are moved opaquely. See the "opaqueMoving"
       property for details.

void QMainWindow::setRightJustification ( bool ) [virtual slot]
       Sets whether the main window right-justifies its dock windows. See the
       "rightJustification" property for details.

void QMainWindow::setToolBarsMovable ( bool ) [slot]
       This function is obsolete. It is provided to keep old source working.
       We strongly advise against using it in new code.

void QMainWindow::setUpLayout () [virtual protected slot]
       Sets up the geometry management of the window. It is called
       automatically when needed, so you shouldn't need to call it.

void QMainWindow::setUsesBigPixmaps ( bool ) [virtual slot]
       Sets whether big pixmaps are enabled. See the "usesBigPixmaps" property
       for details.

void QMainWindow::setUsesTextLabel ( bool ) [virtual slot]
       Sets whether text labels for toolbar buttons are enabled. See the
       "usesTextLabel" property for details.

bool QMainWindow::showDockMenu ( const QPoint & globalPos ) [virtual protected
       slot]
       Shows the dock menu at the position globalPos. The menu lists the dock
       windows so that they can be shown (or hidden), lined up, and possibly
       customized. Returns TRUE if the menu is shown; otherwise returns FALSE.

       If you want a custom menu, reimplement this function. You can create
       the menu from scratch or call createDockWindowMenu() and modify the
       result.

QStatusBar * QMainWindow::statusBar () const
       Returns this main window's status bar. If there isn't one, statusBar()
       creates an empty status bar, and if necessary a tool tip group too.

       See also menuBar() and toolTipGroup().

       Example: qfd/qfd.cpp.

void QMainWindow::toolBarPositionChanged ( QToolBar * ) [signal]
       This function is obsolete. It is provided to keep old source working.
       We strongly advise against using it in new code.

QPtrList<;QToolBar> QMainWindow::toolBars ( Dock dock ) const
       Returns a list of all the toolbars which are in the dock dock area,
       regardless of their state.

       For example, the TornOff dock area may contain closed toolbars but
       these are returned along with the visible toolbars.

       See also dockWindows().

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

QToolTipGroup * QMainWindow::toolTipGroup () const
       Returns this main window's tool tip group. If there isn't one,
       toolTipGroup() creates an empty tool tip group.

       See also menuBar() and statusBar().

QDockArea * QMainWindow::topDock () const
       Returns the Top dock area

       See also bottomDock(), leftDock(), and rightDock().

bool QMainWindow::usesBigPixmaps () const
       Returns TRUE if big pixmaps are enabled; otherwise returns FALSE. See
       the "usesBigPixmaps" property for details.

bool QMainWindow::usesTextLabel () const
       Returns TRUE if text labels for toolbar buttons are enabled; otherwise
       returns FALSE. See the "usesTextLabel" property for details.

void QMainWindow::usesTextLabelChanged ( bool ) [signal]
       This signal is emitted whenever the setUsesTextLabel() is called with a
       value different to the current setting. All widgets that should respond
       to such changes, e.g. toolbar buttons, must connect to this signal.

void QMainWindow::whatsThis () [virtual slot]
       Enters 'What's This?' mode and returns immediately.

       This is the same as QWhatsThis::enterWhatsThisMode(), but implemented
       as a main window object's slot. This way it can easily be used for
       popup menus, for example:

	   QPopupMenu * help = new QPopupMenu( this );
	   help->insertItem( "What's &This", this , SLOT(whatsThis()), SHIFT+Key_F1);

       See also QWhatsThis::enterWhatsThisMode().

   Property Documentation
bool dockWindowsMovable
       This property holds whether the dock windows are movable.

       If TRUE (the default), the user will be able to move movable dock
       windows from one QMainWindow dock area to another, including the
       TearOff area (i.e. where the dock window floats freely as a window in
       its own right), and the Minimized area (where only the dock window's
       handle is shown below the menu bar). Moveable dock windows can also be
       moved within QMainWindow dock areas, i.e. to rearrange them within a
       dock area.

       If FALSE the user will not be able to move any dock windows.

       By default dock windows are moved transparently (i.e. only an outline
       rectangle is shown during the drag), but this setting can be changed
       with setOpaqueMoving().

       See also setDockEnabled() and opaqueMoving.

       Set this property's value with setDockWindowsMovable() and get this
       property's value with dockWindowsMovable().

bool opaqueMoving
       This property holds whether dock windows are moved opaquely.

       If TRUE the dock windows of the main window are shown opaquely (i.e. it
       shows the toolbar as it looks when docked) whilst it is being moved. If
       FALSE (the default) they are shown transparently, (i.e. as an outline
       rectangle).

       Warning: Opaque moving of toolbars and dockwindows is known to have
       several problems. We recommend avoiding the use of this feature for the
       time being. We intend fixing the problems in a future release.

       Set this property's value with setOpaqueMoving() and get this
       property's value with opaqueMoving().

bool rightJustification
       This function is obsolete. It is provided to keep old source working.
       We strongly advise against using it in new code.

       This property holds whether the main window right-justifies its dock
       windows.

       If disabled (the default), stretchable dock windows are expanded, and
       non-stretchable dock windows are given the minimum space they need.
       Since most dock windows are not stretchable, this usually results in an
       unjustified right edge (or unjustified bottom edge for a vertical dock
       area). If enabled, the main window will right-justify its dock windows.

       See also QDockWindow::setVerticalStretchable() and
       QDockWindow::setHorizontalStretchable().

       Set this property's value with setRightJustification() and get this
       property's value with rightJustification().

bool usesBigPixmaps
       This property holds whether big pixmaps are enabled.

       If FALSE (the default), the tool buttons will use small pixmaps;
       otherwise big pixmaps will be used.

       Tool buttons and other widgets that wish to respond to this setting are
       responsible for reading the correct state on startup, and for
       connecting to the main window's widget's pixmapSizeChanged() signal.

       Set this property's value with setUsesBigPixmaps() and get this
       property's value with usesBigPixmaps().

bool usesTextLabel
       This property holds whether text labels for toolbar buttons are
       enabled.

       If disabled (the default), the tool buttons will not use text labels.
       If enabled, text labels will be used.

       Tool buttons and other widgets that wish to respond to this setting are
       responsible for reading the correct state on startup, and for
       connecting to the main window's widget's usesTextLabelChanged() signal.

       See also QToolButton::usesTextLabel.

       Set this property's value with setUsesTextLabel() and get this
       property's value with usesTextLabel().

RELATED FUNCTION DOCUMENTATION
QTextStream & operator<;< ( QTextStream & ts, const QMainWindow & mainWindow )
       Writes the layout (sizes and positions) of the dock windows in the dock
       areas of the QMainWindow mainWindow, including Minimized and TornOff
       dock windows, to the text stream ts.

       This can be used, for example, in conjunction with QSettings to save
       the user's layout when the \mainWindow receives a closeEvent.

       See also operator>>() and closeEvent().

QTextStream & operator>> ( QTextStream & ts, QMainWindow & mainWindow )
       Reads the layout (sizes and positions) of the dock windows in the dock
       areas of the QMainWindow mainWindow from the text stream, ts, including
       Minimized and TornOff dock windows. Restores the dock windows and dock
       areas to these sizes and positions. The layout information must be in
       the format produced by operator<<().

       This can be used, for example, in conjunction with QSettings to restore
       the user's layout.

       See also operator<<().
