本实例实现了工具栏中插入QComboBox控件和QSpinBox控件，代码如下：

# -*- coding: utf-8 -*-from PyQt4.QtGui import *from PyQt4.QtCore import *import sysQTextCodec.setCodecForTr(QTextCodec.codecForName("utf8"))class MainWindow(QMainWindow):    def __init__(self,parent=None):        super(MainWindow,self).__init__(parent)        self.setWindowTitle(self.tr("工具栏插入控件"))        self.text = QTextEdit()        self.text.setReadOnly(True)        self.setCentralWidget(self.text);                self.ToolBar=self.addToolBar("Contral")        self.label1 = QLabel(self.tr("ctrl1:"))        self.box = QComboBox()        self.box.insertItem(0,self.tr("ComboBox 1"))        self.box.insertItem(1,self.tr("ComboBox 2"))        self.box.insertItem(2,self.tr("ComboBox 3"))        self.ToolBar.addWidget(self.label1)        self.ToolBar.addWidget(self.box)        self.ToolBar.addSeparator()        self.label2 = QLabel(self.tr("ctrl2:"))        self.spin = QSpinBox()        self.spin.setRange(1,10)        self.ToolBar.addWidget(self.label2)        self.ToolBar.addWidget(self.spin)        self.doc = QString()        self.spinStr = QString()                self.box.currentIndexChanged.connect(self.slotComboBox)        self.spin.valueChanged.connect(self.slotSpinBox)        def slotComboBox(self):        self.combo = str(self.box.currentIndex() + 1  )        self.doc = "QComboBox:"  + self.combo + "\n" + "QSpinBox:" + self.spinStr.setNum(self.spin.value())        self.text.setText(self.doc)                def slotSpinBox(self):        doc = "QComboBox:" + str(self.box.currentIndex() + 1) + "\n" + "QSpinBox:" + self.spinStr.setNum(self.spin.value())        self.text.setText(doc)            app=QApplication(sys.argv)main=MainWindow()main.show()app.exec_()
