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_())

 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_())
