.SH DESCRIPTION
|
|
The QMainWindow class provides a main application window, with a menu bar, dock windows (e.g. for toolbars), and a status bar.
|
|
.PP
|
|
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 TQt Designer. We'll briefly review adding menu items and toolbar buttons then describe the facilities of QMainWindow itself.

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

|

|
|
ApplicationWindow *mw = new ApplicationWindow();
|
|
.br
|
|
mw->setCaption( "TQt Example - Application" );

.br

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 )
|
|
.PP
|
|
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 \fIthis\fR pointer.
|
|
.PP
|
|
.nf
|
|
.br
|
|
QPopupMenu * help = new QPopupMenu( this );
|
|
.br
|
|
menuBar()->insertItem( "&Help", help );
|
|
.br
|
|
.br
|
|
help->insertItem( "&About", this, SLOT(about()), Key_F1 );
|
|
.fi
|
|
.PP
|
|
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.
|
|
.PP
|
|
.nf
|
|
.br
|
|
QToolBar * fileTools = new QToolBar( this, "file operations" );
|
|
.br
|
|
fileTools->setLabel( "File Operations" );
|
|
.fi
|
|
.PP
|
|
.nf
|
|
.br
|
|
QToolButton * fileOpen
|
|
.br
|
|
= new QToolButton( openIcon, "Open File", QString::null,
|
|
.br
|
|
this, SLOT(choose()), fileTools, "open file" );
|
|
.fi
|
|
.PP
|
|
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.
|
|
.PP
|
|
.nf
|
|
.br
|
|
e = new QTextEdit( this, "editor" );
|
|
.br
|
|
e->setFocus();
|
|
.br
|
|
setCentralWidget( e );
|
|
.br
|
|
statusBar()->message( "Ready", 2000 );
|
|
.fi
|
|
.PP
|
|
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.
|
|
.PP
|
|
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...",
|
|
.br
|
|
CTRL+Key_O, this, "open" );
|
|
.br
|
|
connect( fileOpenAction, SIGNAL( activated() ) , this, SLOT( choose() ) );
|
|
.fi
|
|
.PP
|
|
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 \fIor\fR the toolbar button.
|
|

QPopupMenu * file = new QPopupMenu( this );

|
|
.nf
|
|
.br
|
|
fileOpenAction->addTo( file );
|
|
.fi
|
|
.PP
|
|
The extract above shows the creation of a popup menu. We add the menu to the QMainWindow's menu bar and add our action.
|
|
.PP
|
|
.nf
|
|
.br
|
|
QToolBar * fileTools = new QToolBar( this, "file operations" );
|
|
.br

|
fileTools->setLabel( "File Operations" );
|
|
.br
|
|
fileOpenAction->addTo( fileTools );
|
|
.fi
|
|
.PP
|
|
Here we create a new toolbar as a child of the QMainWindow and add our action to the toolbar.
|
|
.PP
|
|
We'll now explore the functionality offered by QMainWindow.
|
|
.PP
|
|
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.
|
|
.PP
|
|
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.
|
|
.PP
|
|
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.
|
|
.PP
|
|
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.)
|
|
.PP
|
|
Some functions change the appearance of a QMainWindow globally:
|
|
.TP
|
|
QDockWindow::setHorizontalStretchable() and QDockWindow::setVerticalStretchable() are used to make specific dock windows or toolbars stretchable.
|
|
.TP
|
|
setUsesBigPixmaps() is used to set whether tool buttons should draw small or large pixmaps (see QIconSet for more information).
|
|
.TP
|
|
setUsesTextLabel() is used to set whether tool buttons should display a textual label in addition to pixmaps (see QToolButton for more information).
|
|
.PP
|
|
The user can drag dock windows into any enabled docking area. Dock windows can also be dragged \fIwithin\fR 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().
|
|
.PP
|
|
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.
|
|
.PP
|
|
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().
|
|
.PP
|
|
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.
|
|
.PP
|
|
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:
|
|
.PP
|
|
.nf
|
|
.br
|
|
QToolBar *tb = new QToolBar( this );
|
|
.br
|
|
addDockWindow( tb, tr( "Menubar" ), Top, FALSE );
|
|
.br
|
|
QMenuBar *mb = new QMenuBar( tb );
|
|
.br
|
|
mb->setFrameStyle( QFrame::NoFrame );
|
|
.br
|
|
tb->setStretchableWidget( mb );
|
|
.br
|
|
setDockEnabled( tb, Left, FALSE );
|
|
.br
|
|
setDockEnabled( tb, Right, FALSE );
|
|
.br
|
|
.fi
|
|

|
|
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:

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.

Reimplemented from QObject.
|
|
.SH "QPopupMenu * QMainWindow::createDockWindowMenu ( DockWindows dockWindows = AllDockWindows ) const"
|
|
Creates the dock window menu which contains all toolbars (if \fIdockWindows\fR is OnlyToolBars ), all dock windows (if \fIdockWindows\fR is NoToolBars) or all toolbars and dock windows (if \fIdockWindows\fR is AllDockWindows - the default).
|
|
.PP
|
|
This function is called internally when necessary, e.g. when the user right clicks a dock area (providing isDockMenuEnabled() returns TRUE).
|
|
.PP
|
|
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).
|
|
.PP
|
|
The list and the state are always kept up-to-date.
|
|
.PP
|
|
Toolbars and dock windows which are not appropriate in the current context (see setAppropriate()) are not listed in the menu.
|
|
.PP
|
|
The menu also has a menu item for lining up the dock windows.
|
|
.PP
|
|
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.
|
|
.SH "void QMainWindow::customize ()\fC [virtual slot]\fR"
|
|
This function is called when the user clicks the Customize menu item on the dock window menu.
|
|
.PP
|
|
The customize menu item will only appear if isCustomizable() returns TRUE (it returns FALSE by default).
|
|
.PP
|
|
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.
|
|
.PP
|
|
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.
|
|
.PP
|
|

.SH "bool QMainWindow::getLocation ( QDockWindow * dw, Dock & dock, int & index, bool & nl, int & extraOffset ) const"
|
|
Finds the location of the dock window \fIdw\fR.
|
|
.PP
|
|
If the \fIdw\fR dock window is found in the main window the function returns TRUE and populates the \fIdock\fR variable with the dw's dock area and the \fIindex\fR with the dw's position within the dock area. It also sets \fInl\fR to TRUE if the \fIdw\fR begins a new line (otherwise FALSE), and \fIextraOffset\fR with the dock window's offset.
|
|
.PP
|
|
If the \fIdw\fR dock window is not found then the function returns FALSE and the state of \fIdock\fR, \fIindex\fR, \fInl\fR and \fIextraOffset\fR is undefined.

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:
|
|
.PP
|
|
.nf
|
|
.br
|
|
QPopupMenu * help = new QPopupMenu( this );
|
|
.br
|
|
help->insertItem( "What's &This", this , SLOT(whatsThis()), SHIFT+Key_F1);
|
|
.br
|
|
.fi
|
|
.PP
|
|

.SS "Property Documentation"
|
|
.SH "bool dockWindowsMovable"
|
|
This property holds whether the dock windows are movable.
|
|
.PP
|
|
If TRUE (the default), the user will be able to move movable dock windows from one QMainWindow dock area to another, including the \fCTearOff\fR 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.
|
|
.PP
|
|
If FALSE the user will not be able to move any dock windows.
|
|
.PP
|
|
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().
|
|
.PP
|
|
See also setDockEnabled() and opaqueMoving.
|
|
.PP
|
|
Set this property's value with setDockWindowsMovable() and get this property's value with dockWindowsMovable().
|
|
.SH "bool opaqueMoving"
|
|
This property holds whether dock windows are moved opaquely.
|
|
.PP
|
|
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).
|
|
.PP
|
|
\fBWarning:\fR 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.
|
|
.PP
|
|
Set this property's value with setOpaqueMoving() and get this property's value with opaqueMoving().
|
|
.SH "bool rightJustification"
|
|
\fBThis function is obsolete.\fR It is provided to keep old source working. We strongly advise against using it in new code.
|
|
.PP
|
|
This property holds whether the main window right-justifies its dock windows.
|
|
.PP
|
|
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.
|
|
.PP
|
|
See also QDockWindow::setVerticalStretchable() and QDockWindow::setHorizontalStretchable().
|
|
.PP
|
|
Set this property's value with setRightJustification() and get this property's value with rightJustification().
|
|
.SH "bool usesBigPixmaps"
|
|
This property holds whether big pixmaps are enabled.
|
|
.PP
|
|
If FALSE (the default), the tool buttons will use small pixmaps; otherwise big pixmaps will be used.
|
|
.PP
|
|
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.
|
|
.PP
|
|
Set this property's value with setUsesBigPixmaps() and get this property's value with usesBigPixmaps().
|
|
.SH "bool usesTextLabel"
|
|
This property holds whether text labels for toolbar buttons are enabled.
|
|
.PP
|
|
If disabled (the default), the tool buttons will not use text labels. If enabled, text labels will be used.
|
|
.PP
|
|
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.
|
|
.PP
|
|
See also QToolButton::usesTextLabel.
|
|
.PP
|
|
Set this property's value with setUsesTextLabel() and get this property's value with usesTextLabel().
|
|
.SH RELATED FUNCTION DOCUMENTATION
|
|
.SH "QTextStream & operator<< ( QTextStream & ts, const QMainWindow & mainWindow )"
|
|
Writes the layout (sizes and positions) of the dock windows in the dock areas of the QMainWindow \fImainWindow\fR, including Minimized and TornOff dock windows, to the text stream \fIts\fR.
|
|
.PP
|
|
This can be used, for example, in conjunction with QSettings to save the user's layout when the \\mainWindow receives a closeEvent.
|
|
.PP
|
|
See also operator>>() and closeEvent().
|
|
.SH "QTextStream & operator>> ( QTextStream & ts, QMainWindow & mainWindow )"
|
|
Reads the layout (sizes and positions) of the dock windows in the dock areas of the QMainWindow \fImainWindow\fR from the text stream, \fIts\fR, 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<<().
|
|
.PP
|
|
This can be used, for example, in conjunction with QSettings to restore the user's layout.
|
|
.PP
|
