PyQt5 – 进度条的 resetFormat() 方法

我们知道我们可以使用setFormat方法设置格式，格式允许我们将格式设置为百分比或文本到进度条。 resetFormat方法用于清除进度条的所有格式并将其恢复为默认值，即'%p%'，即百分比值+百分比符号。

Syntax : bar.resetFormat()

Argument : It takes no argument.

Action performed : It will clear all the previous formatting of that progress bar and set it to default.

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
        bar = QProgressBar(self)
  
        # setting geometry to progress bar
        bar.setGeometry(200, 100, 200, 30)
  
        # setting the value
        bar.setValue(70)
  
        # setting formatting to display text
        bar.setFormat("Geeks")
  
        # setting alignment to center
        bar.setAlignment(Qt.AlignCenter)
  
        # clearing the format
        # setting it back to defaults
        bar.resetFormat()
  
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
