  \class QToolButton qtoolbutton.h

  \brief The QToolButton class provides a quick-access button to
  commands or options, usually used inside a QToolBar.

  \ingroup basic
  \mainclass

  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 normally show a text label, but an icon.  Its
  classic usage is to select tools, for example the "pen" tool in a
  drawing program. This would be implemented with a QToolButton as
  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 QIconSet. 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 user is pointing at it.

  The button's look and dimension is adjustable with
  setUsesBigPixmap() and setUsesTextLabel(). When used inside a
  QToolBar, the button automatically adjusts to QMainWindow's settings
  (see QMainWindow::setUsesTextLabel() and
  QMainWindow::setUsesBigPixmaps()).

  A tool button can offer additional choices in a popup menu.  The
  feature is sometimes used with the "Back" button in a web browser.
  After pressing the button down for awhile, a menu pops up showing
  all possible pages to browse back.  With QToolButton you can set a
  popup menu using setPopup(). The default delay is 600ms; you may
  adjust it with setPopupDelay().
