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, QLabel
import sys
class 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, QPushButton
import sys
class 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_())
