1、代码1：

（1）进度条等显示在主窗口状态栏的右端，代码如下：

from PyQt5.QtWidgets import QMainWindow, QProgressBar, QApplication, QLabelimport sysclass SampleBar(QMainWindow):  """Main Application"""  def __init__(self, parent = None):    print('Starting the main Application')    super(SampleBar, self).__init__(parent)    self.initUI()  def initUI(self):    # Pre Params:    self.setMinimumSize(800, 600)    # File Menus & Status Bar:    self.statusBar().showMessage('准备中...')    self.progressBar = QProgressBar()    self.label = QLabel()    self.label2 = QLabel()    self.label.setText("正在计算： ")    self.label2.setText("正在计算： ")    self.statusBar().addPermanentWidget(self.label)    self.statusBar().addPermanentWidget(self.label2)    self.statusBar().addPermanentWidget(self.progressBar)    # self.statusBar().addWidget(self.progressBar)    # This is simply to show the bar    self.progressBar.setGeometry(0, 0, 100, 5)    self.progressBar.setRange(0, 500) # 设置进度条的范围    self.progressBar.setValue(100)if __name__ == '__main__':  app = QApplication(sys.argv)  main2 = SampleBar()  main2.show()  sys.exit(app.exec_())

2、代码2：

（1）进度条等显示在主窗口状态栏的左端，代码如下：

from PyQt5.QtWidgets import QMainWindow, QProgressBar, QApplication, QLabel, /  QStatusBar, QPushButtonimport sysclass SampleBar(QMainWindow):  """Main Application"""  def __init__(self, parent = None):    # print('Starting the main Application')    super(SampleBar, self).__init__(parent)    self.initUI()  def initUI(self):    # Pre Params:    self.setMinimumSize(800, 600)    # File Menus & Status Bar:    self.statusBar = QStatusBar()    self.statusBar.setStyleSheet('QStatusBar::item {border: none;}')    self.setStatusBar(self.statusBar)    self.statusBar.showMessage('准备')    self.progressBar = QProgressBar()    self.pushbutton = QPushButton("点这里")    self.label = QLabel()    self.label2 = QLabel()    self.label.setText("开始计算 ")    self.label2.setText("正在计算： ")    # self.statusBar.addWidget(self.label, 0)    self.statusBar.addPermanentWidget(self.label, stretch=2)    self.statusBar.addPermanentWidget(self.label2, stretch=0)    self.statusBar.addPermanentWidget(self.progressBar, stretch=4)    # self.statusBar().addWidget(self.progressBar)    # This is simply to show the bar    # self.progressBar.setGeometry(0, 0, 100, 5)    self.progressBar.setRange(0, 500) # 设置进度条的范围    self.progressBar.setValue(20)if __name__ == '__main__':  app = QApplication(sys.argv)  main2 = SampleBar()  main2.show()  sys.exit(app.exec_())
