DESCRIPTION
The QToolBar class provides a movable panel containing widgets such as
tool buttons.
A toolbar is a panel that contains a set of controls, usually
represented by small icons. It's purpose is to provide quick access to
frequently used commands or options. Within a QMainWindow the user can
drag toolbars within and between the dock areas. Toolbars can also be
dragged out of any dock area to float freely as top-level windows.
QToolBar is a specialization of QDockWindow, and so provides all the
functionality of a QDockWindow.
To use QToolBar you simply create a QToolBar as a child of a
QMainWindow, create a number of QToolButton widgets (or other widgets)
in left to right (or top to bottom) order and call addSeparator() when
you want a separator. When a toolbar is floated the caption used is the
label given in the constructor call. This can be changed with
setLabel().
QToolBar * fileTools = new QToolBar( this, "file operations" );
fileTools->setLabel( "File Operations" );
fileOpenAction->addTo( fileTools );
fileSaveAction->addTo( fileTools );
This extract from the application/application.cpp example shows the
creation of a new toolbar as a child of a QMainWindow and adding two
QActions.
You may use most widgets within a toolbar, with QToolButton and
QComboBox being the most common.
If you create a new widget on an already visible QToolBar, this widget
will automatically become visible without needing a show() call. (This
differs from every other Qt widget container. We recommend calling
show() anyway since we hope to fix this anomaly in a future release.)
QToolBars, like QDockWindows, are located in QDockAreas or float as
top-level windows. QMainWindow provides four QDockAreas (top, left,
right and bottom). When you create a new toolbar (as in the example
above) as a child of a QMainWindow the toolbar will be added to the top
dock area. You can move it to another dock area (or float it) by
calling QMainWindow::moveDockWindow(). QDock areas lay out their
windows in Lines.
If the main window is resized so that the area occupied by the toolbar
is too small to show all its widgets a little arrow button (which looks
like a right-pointing chevron, '»') will appear at the right or
bottom of the toolbar depending on its orientation. Clicking this
button pops up a menu that shows the 'overflowing' items. QToolButtons
are represented in the menu using their textLabel property, other
QButton subclasses are represented using their text property, and
QComboBoxes are represented as submenus, with the caption text being
used in the submenu item.
Usually a toolbar will get precisely the space it needs. However, with
setHorizontalStretchable(), setVerticalStretchable() or
setStretchableWidget() you can tell the main window to expand the
toolbar to fill all available space in the specified orientation.
The toolbar arranges its buttons either horizontally or vertically (see
orientation() for details). Generally, QDockArea will set the
orientation correctly for you, but you can set it yourself with
setOrientation() and track any changes by connecting to the
orientationChanged() signal.
You can use the clear() method to remove all items from a toolbar.

MEMBER FUNCTION DOCUMENTATIONQToolBar::QToolBar ( const QString & label, QMainWindow *, ToolBarDock =
DockTop, bool newLine = FALSE, const char * name = 0 )
This function is obsolete. It is provided to keep old source working.
We strongly advise against using it in new code.
QToolBar::QToolBar ( const QString & label, QMainWindow * mainWindow, QWidget
* parent, bool newLine = FALSE, const char * name = 0, WFlags f = 0 )
Constructs an empty horizontal toolbar.
The toolbar is called name and is a child of parent and is managed by
mainWindow. The label and newLine parameters are passed straight to
QMainWindow::addDockWindow(). name and the widget flags f are passed on
to the QDockWindow constructor.
Use this constructor if you want to create torn-off (undocked,
floating) toolbars or toolbars in the status bar.
QToolBar::QToolBar ( QMainWindow * parent = 0, const char * name = 0 )
This is an overloaded member function, provided for convenience. It
behaves essentially like the above function.
Constructs an empty toolbar called name, with parent parent, in its
parent's top dock area, without any label and without requiring a
newline.
void QToolBar::addSeparator ()
Adds a separator to the right/bottom of the toolbar.
Examples:
void QToolBar::clear () [virtual]
Deletes all the toolbar's child widgets.
QString QToolBar::label () const
Returns the toolbar's label. See the "label" property for details.
QMainWindow * QToolBar::mainWindow () const
Returns a pointer to the QMainWindow which manages this toolbar.
void QToolBar::setLabel ( const QString & ) [virtual]
Sets the toolbar's label. See the "label" property for details.
void QToolBar::setStretchableWidget ( QWidget * w ) [virtual]
Sets the widget w to be expanded if this toolbar is requested to
stretch.
The request to stretch might occur because QMainWindow right-justifies
the dock area the toolbar is in, or because this toolbar's
isVerticalStretchable() or isHorizontalStretchable() is set to TRUE.
If you call this function and the toolbar is not yet stretchable,
setStretchable() is called.
See also QMainWindow::rightJustification, setVerticalStretchable(), and
setHorizontalStretchable().
Examples:
Property Documentation
QString label
This property holds the toolbar's label.
If the toolbar is floated the label becomes the toolbar window's
caption. There is no default label text.
Set this property's value with setLabel() and get this property's value
with label().
