示例1: addWidget
/*!
Inserts the given \a widget in front of the toolbar item
associated with the \a before action.
Note: You should use QAction::setVisible() to change the
visibility of the widget. Using QWidget::setVisible(),
QWidget::show() and QWidget::hide() does not work.
\sa addWidget()
*/

{
QWidgetAction *action = new QWidgetAction(this);
action->setDefaultWidget(widget);
action->d_func()->autoCreated = true;
insertAction(before, action);
return action;
}示例2: insertWidget
/*!
Adds the given \a widget to the toolbar as the toolbar's last
item.
The toolbar takes ownership of \a widget.
If you add a QToolButton with this method, the tools bar's
Qt::ToolButtonStyle will not be respected.
\note You should use QAction::setVisible() to change the
visibility of the widget. Using QWidget::setVisible(),
QWidget::show() and QWidget::hide() does not work.
