我有多个工具栏，彼此相邻。我希望工具栏首先是第三个或在另一个之前。我无法弄清楚如何实现它。有人可以帮忙吗？
这是.cpp
QPixmap pix(16, 16);
pix.fill(Qt::black);
fntColorAct = new QAction(pix, tr("&Color"), this);
connect(fntColorAct, SIGNAL(triggered()), this, SLOT(fontColor()));
fontToolBar = new QToolBar(this);
fontToolBar->setAllowedAreas(Qt::TopToolBarArea | Qt::BottomToolBarArea);
addToolBar(fontToolBar);
fontToolBar->setWindowTitle(tr("&Format Actions"));
addToolBarBreak(Qt::TopToolBarArea);
addToolBar(fontToolBar);
cmbStyle = new QComboBox(fontToolBar);
fontToolBar->addWidget(cmbStyle);
cmbStyle->addItem("Standard");
cmbStyle->addItem("Bullet List (Disc)");
cmbStyle->addItem("Bullet List (Circle)");
cmbStyle->addItem("Bullet List (Square)");
cmbStyle->addItem("Ordered List (Decimal)");
cmbStyle->addItem("Ordered List (Alpha lower)");
cmbStyle->addItem("Ordered List (Alpha upper)");
cmbStyle->addItem("Ordered List (Roman lower)");
cmbStyle->addItem("Ordered List (Roman upper)");
connect(cmbStyle, SIGNAL(activated(int)), this, SLOT(fontStyle(int)));
fntComboBox = new QFontComboBox(fontToolBar);
fontToolBar->addWidget(fntComboBox);
connect(fntComboBox, SIGNAL(activated(QString)), this, SLOT(fontFamily(QString)));
cmbSize = new QComboBox(fontToolBar);
cmbSize->setObjectName("cmbSize");
fontToolBar->addWidget(cmbSize);
cmbSize->setEditable(true);
QFontDatabase database;
foreach(int size, database.standardSizes())
cmbSize->addItem(QString::number(size));
connect(cmbSize, SIGNAL(activated(QString)),
this, SLOT(fontSize(QString)));
cmbSize->setCurrentIndex(cmbSize->findText(
QString::number(QApplication::font().pointSize())));
}

fileMenu = menuBar()->addMenu(tr("&File"));
fileMenu->addAction(newAct);
