\class QMainWindow qmainwindow.h
|
|
|
|
\brief The QMainWindow class provides a main application window,
|
|
|
|
with a menu bar, dock windows (e.g. for toolbars), and a status
|
|
|
|
bar.
|
|
|
|
|
|
|
|
\ingroup application
|
|
|
|
\mainclass
|
|
|
|
|
|
|
|
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 \link designer-manual.book Qt
|
|
|
|
Designer\endlink. We'll briefly review adding menu items and
|
|
|
|
toolbar buttons then describe the facilities of QMainWindow
|
|
|
|
itself.
|
|
|
|
|
|
|
|
\code
|
|
|
|
QMainWindow *mw = new QMainWindow;
|
|
|
|
QTextEdit *edit = new QTextEdit( mw, "editor" );
|
|
|
|
edit->setFocus();
|
|
|
|
mw->setCaption( "Main Window" );
|
|
|
|
mw->setCentralWidget( edit );
|
|
|
|
mw->show();
|
|
|
|
\endcode
|
|
|
|
|
|
|
|
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.
|
|

|
|
\skipto ApplicationWindow
|

\printuntil 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 \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 QMainWindow instance
|
|
|
|
directly we can add menu items and toolbars just as easily by
|
|
|
|
passing the QMainWindow instance as the parent instead of the \e
|
|
|
|
this pointer.

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.

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 \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 QMainWindow
|
|
|
|
as the parent.

|

|
|
\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 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.

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.

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

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 (\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 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.
|
|
|
|
|
|
|
|
\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{QMainWindow::DockWindows}.)
|
|
|
|
|
|
|
|
Some functions change the appearance of a QMainWindow globally:
|
|
|
|
\list
|
|
|
|
\i QDockWindow::setHorizontalStretchable() and
|
|
|
|
QDockWindow::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 QIconSet for more information).
|
|
|
|
\i setUsesTextLabel() is used to set whether tool buttons
|
|
|
|
should display a textual label in addition to pixmaps
|
|
|
|
(see QToolButton 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
|
|
|
|
QDockWindow::caption() or QToolBar::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 QMenuBar 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
|
|
|
|
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 );
|
|
|
|
\endcode
|
|
|
|
|
|
|
|
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:
|
|
|
|
|
|
|
|
\code
|
|
|
|
QFile file( filename );
|
|
|
|
if ( file.open( IO_WriteOnly ) ) {
|
|
|
|
QTextStream 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
|
|
|
|
QFile file( filename );
|
|
|
|
if ( file.open( IO_ReadOnly ) ) {
|
|
|
|
QTextStream stream( &file );
|
|
|
|
stream >> *mainWindow;
|
|
|
|
file.close();
|
|
|
|
}
|
|
|
|
\endcode
|
|
|
|
|
|
|
|
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 \l QDockArea) to the subclass since
|
|
|
|
QMainWindow provides functionality specific to the standard dock
|
|
|
|
areas it provides.
