Qt has QMainWindow and its \l{Main Window and Related Classes}{related classes} for main window management. QMainWindow has its own layout to which you can add \l{QToolBar}s, \l{QDockWidget}s, a QMenuBar, and a QStatusBar. The layout has a center area that can be occupied by any kind of widget. You can see an image of the layout below. \image mainwindowlayout.png \note Creating a main window without a central widget is not supported. You must have a central widget even if it is just a placeholder. \section1 Creating Main Window Components A central widget will typically be a standard Qt widget such as a QTextEdit or a QGraphicsView. Custom widgets can also be used for advanced applications. You set the central widget with \c setCentralWidget(). Main windows have either a single (SDI) or multiple (MDI) document interface. You create MDI applications in Qt by using a QMdiArea as the central widget. We will now examine each of the other widgets that can be added to a main window. We give examples on how to create and add them. \section2 Creating Menus Qt implements menus in QMenu and QMainWindow keeps them in a QMenuBar. \l{QAction}{QAction}s are added to the menus, which display them as menu items. You can add new menus to the main window's menu bar by calling \c menuBar(), which returns the QMenuBar for the window, and then add a menu with QMenuBar::addMenu(). QMainWindow comes with a default menu bar, but you can also set one yourself with \c setMenuBar(). If you wish to implement a custom menu bar (i.e., not use the QMenuBar widget), you can set it with \c setMenuWidget(). An example of how to create menus follows: \code void MainWindow::createMenus() { fileMenu = menuBar()->addMenu(tr("&File")); fileMenu->addAction(newAct); fileMenu->addAction(openAct); fileMenu->addAction(saveAct); \endcode The \c createPopupMenu() function creates popup menus when the main window receives context menu events. The default implementation generates a menu with the checkable actions from the dock widgets and toolbars. You can reimplement \c createPopupMenu() for a custom menu. \section2 Creating Toolbars Toolbars are implemented in the QToolBar class. You add a toolbar to a main window with \c addToolBar(). You control the initial position of toolbars by assigning them to a specific Qt::ToolBarArea. You can split an area by inserting a toolbar break - think of this as a line break in text editing - with \c addToolBarBreak() or \c insertToolBarBreak(). You can also restrict placement by the user with QToolBar::setAllowedAreas() and QToolBar::setMovable(). The size of toolbar icons can be retrieved with \c iconSize(). The sizes are platform dependent; you can set a fixed size with \c setIconSize(). You can alter the appearance of all tool buttons in the toolbars with \c setToolButtonStyle(). An example of toolbar creation follows: \code void MainWindow::createToolBars() { fileToolBar = addToolBar(tr("File")); fileToolBar->addAction(newAct); \endcode \section2 Creating Dock Widgets Dock widgets are implemented in the QDockWidget class. A dock widget is a window that can be docked into the main window. You add dock widgets to a main window with \c addDockWidget(). There are four dock widget areas as given by the Qt::DockWidgetArea enum: left, right, top, and bottom. You can specify which dock widget area that should occupy the corners where the areas overlap with \c setCorner(). By default each area can only contain one row (vertical or horizontal) of dock widgets, but if you enable nesting with \c setDockNestingEnabled(), dock widgets can be added in either direction. Two dock widgets may also be stacked on top of each other. A QTabBar is then used to select which of the widgets should be displayed. We give an example of how to create and add dock widgets to a main window: \snippet mainwindowsnippet.cpp 0 \section2 The Status Bar You can set a status bar with \c setStatusBar(), but one is created the first time \c statusBar() (which returns the main window's status bar) is called. See QStatusBar for information on how to use it. \section1 Storing State QMainWindow can store the state of its layout with \c saveState(); it can later be retrieved with \c restoreState(). It is the position and size (relative to the size of the main window) of the toolbars and dock widgets that are stored. \sa QMenuBar, QToolBar, QStatusBar, QDockWidget, {Application Example}, {Dock Widgets Example}, {MDI Example}, {SDI Example}, {Menus Example} */ /*! \fn void QMainWindow::iconSizeChanged(const QSize &iconSize) This signal is emitted when the size of the icons used in the window is changed.
