+    \class QToolButton
+    \brief The QToolButton class provides a quick-access button to
+    commands or options, usually used inside a QToolBar.
+
+    \ingroup basicwidgets
+
+
+    A tool button is a special button that provides quick-access to
+    specific commands or options. As opposed to a normal command
+    button, a tool button usually doesn't show a text label, but shows
+    an icon instead.
+
+    Tool buttons are normally created when new QAction instances are
+    created with QToolBar::addAction() or existing actions are added
+    to a toolbar with QToolBar::addAction(). It is also possible to
+    construct tool buttons in the same way as any other widget, and
+    arrange them alongside other widgets in layouts.
+
+    One classic use of a tool button is to select tools; for example,
+    the "pen" tool in a drawing program. This would be implemented
+    by using a QToolButton as a toggle button (see setToggleButton()).
+
+    QToolButton supports auto-raising. In auto-raise mode, the button
+    draws a 3D frame only when the mouse points at it. The feature is
+    automatically turned on when a button is used inside a QToolBar.
+    Change it with setAutoRaise().
+
+    A tool button's icon is set as QIcon. This makes it possible to
+    specify different pixmaps for the disabled and active state. The
+    disabled pixmap is used when the button's functionality is not
+    available. The active pixmap is displayed when the button is
+    auto-raised because the mouse pointer is hovering over it.
+
+    The button's look and dimension is adjustable with
+    setToolButtonStyle() and setIconSize(). When used inside a
+    QToolBar in a QMainWindow, the button automatically adjusts to
+    QMainWindow's settings (see QMainWindow::setToolButtonStyle() and
+    QMainWindow::setIconSize()). Instead of an icon, a tool button can
+    also display an arrow symbol, specified with
+    \l{QToolButton::arrowType} {arrowType}.
+
+    A tool button can offer additional choices in a popup menu. The
+    popup menu can be set using setMenu(). Use setPopupMode() to
+    configure the different modes available for tool buttons with a
+    menu set. The default mode is DelayedPopupMode which is sometimes
+    used with the "Back" button in a web browser.  After pressing and
+    holding the button down for a while, a menu pops up showing a list
+    of possible pages to jump to. The default delay is 600 ms; you can
+    adjust it with setPopupDelay().
