PyQt5 – 进度条的 format() 方法

我们可以在 Progress Bar 中使用setFormat方法设置格式和显示文本， format方法用于获取进度条的格式。

注意：进度条的默认格式是'%p%'，即用于打印百分比，所以如果没有设置特定格式， format方法将返回'%p%'。

Syntax : bar.format()

Argument : It takes no argument.

Return : It return string.

下面是这个方法的实现。

# 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
        bar1 = QProgressBar(self)
  
        # setting geometry to progress bar
        bar1.setGeometry(200, 100, 200, 30)
  
        # setting the value
        bar1.setValue(70)
  
        # getting format of bar1
        format1 = bar1.format()
  
        # printing the format1
        print("format of bar 1 : " + format1)
  
        bar2 = QProgressBar(self)
  
        # setting geometry to progress bar
        bar2.setGeometry(200, 200, 200, 30)
  
        # setting the value
        bar2.setValue(50)
  
        # setting text using format
        bar2.setFormat("Geeks")
  
        # getting format of bar2
        format2 = bar2.format()
  
        # printing the format2
        print("format of bar 2 : " + format2)
  
  
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：

format of bar 1 : %p%
format of bar 2 : Geeks
