TQMainWindow 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 Q_SLOTS that are called when the user clicks menu items or toolbar buttons. You can also create main windows using \link designer-manual.book TQt Designer\endlink. We'll briefly review adding menu items and toolbar buttons then describe the facilities of TQMainWindow itself. \code TQMainWindow *mw = new TQMainWindow; TQTextEdit *edit = new TQTextEdit( mw, "editor" ); edit->setFocus(); mw->setCaption( "Main Window" ); mw->setCentralWidget( edit ); mw->show(); \endcode TQMainWindows 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. \quotefile application/main.cpp \skipto ApplicationWindow \printuntil show In the extract above ApplicationWindow is a subclass of TQMainWindow that we must write for ourselves; this is the usual approach to using TQMainWindow. (The source for the extracts in this description are taken from \l application/main.cpp, \l application/application.cpp, \l action/main.cpp, and \l action/application.cpp ) When subclassing we add the menu items and toolbars in the subclass's constructor. If we've created a TQMainWindow instance directly we can add menu items and toolbars just as easily by passing the TQMainWindow instance as the tqparent instead of the \e this pointer. \quotefile application/application.cpp \skipto help = new \printuntil about Here we've added a new menu with one menu item. The menu has been inserted into the menu bar that TQMainWindow provides by default and which is accessible through the menuBar() function. The slot will be called when the menu item is clicked. \quotefile application/application.cpp \skipto fileTools \printuntil setLabel \skipto TQToolButton \printuntil open file This extract shows the creation of a toolbar with one toolbar button. TQMainWindow supplies four dock areas for toolbars. When a toolbar is created as a child of a TQMainWindow (or derived class) instance it will be placed in a dock area (the \c 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 TQMainWindow as the tqparent. \quotefile application/application.cpp \skipto editor \printuntil statusBar 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 TQStatusBar 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. \quotefile action/application.cpp \skipto TQAction * fileOpen \printline \skipto fileOpenAction \printuntil 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 \e or the toolbar button. \quotefile action/application.cpp \skipto TQPopupMenu * file \printuntil menuBar \skipto fileOpen \printline The extract above shows the creation of a popup menu. We add the menu to the TQMainWindow's menu bar and add our action. \quotefile action/application.cpp \skipto TQToolBar * fileTool \printuntil OpenAction Here we create a new toolbar as a child of the TQMainWindow and add our action to the toolbar. We'll now explore the functionality offered by TQMainWindow. The main window will take care of the dock areas, and the tqgeometry of the central widget, but all other aspects of the central widget are left to you. TQMainWindow automatically detects the creation of a menu bar or status bar if you specify the TQMainWindow as tqparent, 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 tqlayout to make space. TQMainWindow provides a TQToolTipGroup connected to the status bar. The function toolTipGroup() provides access to the default TQToolTipGroup. It isn't possible to set a different tool tip group. New dock windows and toolbars can be added to a TQMainWindow using addDockWindow(). Dock windows can be moved using moveDockWindow() and removed with removeDockWindow(). TQMainWindow allows default dock window (toolbar) docking in all its dock areas (\c Top, \c Left, \c Right, \c 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: \c Top, \c Left, \c Right, \c Bottom, \c Minimized (effectively a 'hidden' dock area) and \c TornOff (floating). See \l TQt::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. TQToolbar is a subclass of TQDockWindow so all functions that work with dock windows work on toolbars in the same way. \target dwm 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 \l{TQMainWindow::DockWindows}.) Some functions change the appearance of a TQMainWindow globally: \list \i TQDockWindow::setHorizontalStretchable() and TQDockWindow::setVerticalStretchable() are used to make specific dock windows or toolbars stretchable. \i setUsesBigPixmaps() is used to set whether tool buttons should draw small or large pixmaps (see TQIconSet for more information). \i setUsesTextLabel() is used to set whether tool buttons should display a textual label in addition to pixmaps (see TQToolButton for more information). \endlist The user can drag dock windows into any enabled docking area. Dock windows can also be dragged \e 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 \c 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 TQDockWindow::caption() or TQToolBar::label()), so if you enable the \c 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 \c 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 TQMenuBar as a stretchable widget inside its own movable dock window and restrict this dock window to only live within the \c Top or \c Bottom dock: \code TQToolBar *tb = new TQToolBar( this ); addDockWindow( tb, tr( "Menubar" ), Top, FALSE ); TQMenuBar *mb = new TQMenuBar( tb ); mb->setFrameStyle( TQFrame::NoFrame ); tb->setStretchableWidget( mb ); setDockEnabled( tb, Left, FALSE ); setDockEnabled( tb, Right, FALSE ); \endcode An application with multiple dock windows can choose to save the current dock window tqlayout in order to restore it later, e.g. in the next session. You can do this by using the streaming operators for TQMainWindow. To save the tqlayout and positions of all the dock windows do this: \code TQFile file( filename ); if ( file.open( IO_WriteOnly ) ) { TQTextStream stream( &file ); stream << *mainWindow; file.close(); } \endcode To restore the dock window positions and sizes (normally when the application is next started), do following: \code TQFile file( filename ); if ( file.open( IO_ReadOnly ) ) { TQTextStream stream( &file ); stream >> *mainWindow; file.close(); } \endcode The TQSettings class can be used in conjunction with the streaming operators to store the application's settings. TQMainWindow's management of dock windows and toolbars is done transparently behind-the-scenes by TQDockArea. For multi-document interfaces (MDI), use a TQWorkspace as the central widget. Adding dock windows, e.g. toolbars, to TQMainWindow's dock areas is straightforward. If the supplied dock areas are not sufficient for your application we suggest that you create a TQWidget subclass and add your own dock areas (see \l TQDockArea) to the subclass since TQMainWindow provides functionality specific to the standard dock areas it provides. \sa TQToolBar TQDockWindow TQStatusBar TQAction TQMenuBar TQPopupMenu TQToolTipGroup TQDialog */ /*! \enum TQt::ToolBarDock \internal */ /*! \enum TQt::Dock Each dock window can be in one of the following positions: \value DockTop above the central widget, below the menu bar. \value DockBottom below the central widget, above the status bar. \value DockLeft to the left of the central widget. \value DockRight to the right of the central widget. \value DockMinimized the dock window is not shown (this is effectively a 'hidden' dock area); the handles of all minimized dock windows are drawn in one row below the menu bar. \value DockTornOff the dock window floats as its own top level window which always stays on top of the main window. \value DockUnmanaged not managed by a TQMainWindow. */ /*! \enum TQMainWindow::DockWindows Right-clicking a dock area will pop-up the dock window menu (createDockWindowMenu() is called automatically).
