DESCRIPTION
The QToolBar class provides a tool bar.
A toolbar is a panel that contains a set of controls,
usually represented by small icons. Its purpose is to
provide quick access to frequently used commands or
options. Within a main window, the user can drag toolbars
freely around and hide them with a click on the toolbar
To use QToolBar, you simply create a QToolBar as child of
a QMainWindow, create a number of QToolButton widgets (or
other widgets) in left to right (or top to bottom) order,
call addSeparator() when you want a separator, and that's
all.
The application/application.cpp example does precisely
this.
You may use any kind of widget within a toolbar, with
QToolButton and QComboBox being the two most common ones.
Each QToolBar lives in a dock in a QMainWindow, and can
optionally start a new line in its dock. Tool bars that
start a new line are always positioned at the left end or
top of the tool bar dock; others are placed next to the
previous tool bar and word-wrapped as necessary. The main
window can be resized to a smaller size than a toolbar
would need to show all items. If this happens QToolbar
shows a little arrow button at the right or bottom end.
When clicking on that button, a popup menu is opened which
shows all items of the toolbar which are outside the
visible area of the mainwindow.
Usually, a toolbar gets just the space it needs. However,
with setHorizontalStretchable()/setVerticalStretchable()
or setStretchableWidget() you can advise the main window
to expand the toolbar to fill all available width in the
specified orientation.
The tool bar arranges its buttons either horizontally or
vertically (see setOrientation() for details). Generally,
QMainWindow will set the orientation correctly for you.
The toolbar emits a signal orientationChanged() each time
the orientation changes, in case some child widgets need
adjustments.
To remove all items from a toolbar, you can use the
clear() method.

Design and GUI Design Handbook: Tool Bar.
MEMBER FUNCTION DOCUMENTATION
QToolBar::QToolBar ( QMainWindow * parent = 0, const char * name
= 0 )
Constructs an empty tool bar in the top dock of its
parent, without any label and without requiring a newline.
This is mostly useless.
QToolBar::QToolBar ( const QString & label, QMainWindow *
mainWindow, QWidget * parent, bool newLine = FALSE, const
Constructs an empty horizontal tool bar with a parent of
parent and managed by mainWindow. The label and newLine
are passed straight to QMainWindow::addToolBar(). name is
the object name and f is the widget flags.
This is the constructor to use if you want to create torn-
off toolbars, or toolbars in the status bar.
QToolBar::QToolBar ( const QString & label, QMainWindow * parent,
QMainWindow::ToolBarDock dock = QMainWindow::Top, bool
newLine = FALSE, const char * name = 0 )
Constructs an empty tool bar which is a child of parent
and managed by parent, initially in dock, labelled and
starting a new line in the dock if newLine is TRUE. name
is the object name, as usual.
QToolBar::~QToolBar ()
Destructs the object and frees any allocated resources.
void QToolBar::addSeparator ()
Adds a separator to the end of the toolbar.
void QToolBar::clear ()
Clears the toolbar, deleting all childwidgets.
bool QToolBar::event ( QEvent * e ) [virtual]
Reimplemented for internal reasons; the API is not
affected.
Reimplemented from QObject.
bool QToolBar::eventFilter ( QObject * obj, QEvent * e )
[virtual]
Reimplemented for internal reasons; the API is not
affected.
Reimplemented from QObject.
void QToolBar::hide () [virtual]
Reimplemented for internal reasons; the API is not
affected.
Reimplemented from QWidget.
bool QToolBar::isHorizontalStretchable () const
Returns whether the toolbar is stretchable horizontally.
A stretchable toolbar fills all available width in a
toolbar dock. A non-stretchable toolbar usually gets just
the space it needs.
See also setHorizontalStretchable(),
setVerticalStretchable() and isVerticalStretchable().
Returns whether the toolbar is stretchable vertically.
A stretchable toolbar fills all available height in a
toolbar dock. A non-stretchable toolbar usually gets just
the space it needs.
See also setHorizontalStretchable(),
setVerticalStretchable() and isHorizontalStretchable().
QString QToolBar::label () const
Returns the label of this tool bar.
See also setLabel().
QMainWindow * QToolBar::mainWindow ()
Returns a pointer to the QMainWindow which controls this
tool bar.
QSize QToolBar::minimumSize () const
Reimplemented for internal reasons; the API is not
affected.
QSize QToolBar::minimumSizeHint () const [virtual]
Reimplemented for internal reasons; the API is not
affected.
Reimplemented from QWidget.
Orientation QToolBar::orientation () const
Returns the current orientation of the toolbar.
void QToolBar::orientationChanged ( Orientation newOrientation )
[signal]
This signal is emitted when the toolbar changed its
orientation to newOrientation.
void QToolBar::paintEvent ( QPaintEvent * ) [virtual protected]
Paint the handle. The Motif style is rather close to
Netscape and even closer to KDE.
Reimplemented from QWidget.
void QToolBar::resizeEvent ( QResizeEvent * e ) [virtual
protected]
Reimplemented for internal reasons; the API is not
affected.
Reimplemented from QWidget.
void QToolBar::setHorizontalStretchable ( bool b )
Sets the toolbar to be horizontally stretchable if b is
TRUE, or non-stretchable otherwise.
toolbar dock. A non-stretchable toolbar usually gets just
the space it needs.
The default is FALSE.
See also QMainWindow::setRightJustification(),
isHorizontalStretchable(), setVerticalStretchable() and
isVerticalStretchable().
void QToolBar::setLabel ( const QString & label ) [virtual]
Sets the label of this tool bar to label. The label is not
currently used; it will be used in a forthcoming tool bar
configuration dialog.
See also label().
void QToolBar::setOrientation ( Orientation newOrientation )
[virtual]
Sets this toolbar to organize its content vertically if
newOrientation is Vertical and horizontally if
newOrientation is Horizontal.
Emits the orientationChanged() signal.
See also orientation().
void QToolBar::setStretchableWidget ( QWidget * w ) [virtual]
Sets w to be expanded if this toolbar is requested to
stretch (because QMainWindow right-justifies the dock it's
in or isVerticalStretchable() or isHorizontalStretchable()
of this toolbar is TRUE).
If you call setStretchableWidget() and the toolbar is not
stretchable yet, setStretchable( ) is called.
See also QMainWindow::setRightJustification(),
setVerticalStretchable() and setHorizontalStretchable().
void QToolBar::setVerticalStretchable ( bool b )
Sets the toolbar to be vertically stretchable if b is
TRUE, or non-stretchable otherwise.
A stretchable toolbar fills the available height in a
toolbar dock. A non-stretchable toolbar usually gets just
the space it needs.
The default is FALSE.
See also QMainWindow::setRightJustification(),
isVerticalStretchable(), setHorizontalStretchable() and
isHorizontalStretchable().
Reimplemented for internal reasons; the API is not
affected.
Reimplemented from QWidget.
void QToolBar::styleChange ( QStyle & ) [virtual protected]
Reimplemented for internal reasons; the API is not
affected.
Reimplemented from QWidget.
