PyQt5 – 进度条的maximum()方法

PyQt5中的进度条允许我们设置进度条的数值范围,maximum方法用于获得进度条的最大值,即范围的上限。该方法返回整数值,如果我们不设置范围,默认为100。

语法: bar.maximum()

参数: 它不需要参数

返回: 它返回整数。

代码。

# importing libraries
from PyQt5.QtWidgets import * 
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import * 
from PyQt5.QtCore import * 
import sys
  
  
class Window(QMainWindow):
  
  
    def __init__(self):
        super().__init__()
  
        # setting title
        self.setWindowTitle("Python ")
  
        # setting geometry
        self.setGeometry(100, 100, 600, 400)
  
        # calling method
        self.UiComponents()
  
        # showing all the widgets
        self.show()
  
    # method for widgets
    def UiComponents(self):
  
        # creating progress bar
        bar = QProgressBar(self)
  
        # setting geometry to progress bar
        bar.setGeometry(200, 150, 200, 30)
  
        # setting maximum value of progress bar to 200
        bar.setMaximum(200)
  
        # setting value to progress bar
        bar.setValue(100)
  
        # getting maximum value of progress bar
        value = bar.maximum()
  
        # creating label to print the value
        label = QLabel("maximum value = " + str(value), self)
  
        # adjusting the size of label
        label.adjustSize()
  
        # moving the label
        label.move(200, 200)
  
        # setting alignment to centre
        bar.setAlignment(Qt.AlignCenter)
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
