PyQt5 – 进度条的 setTextVisible() 方法

我们知道当我们创建一个进度条时，它也会显示百分比。 setTextVisible方法用于设置天气进度条内的文本是否可见，如果我们将其设置为 True 它将是可见的，否则它将不可见。

Syntax : bar.setTextVisible(False)

Argument : It takes bool as argument.

Action performed : It will set the text to invisible.

下面是实现。

# 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(150, 150, 200, 30)
  
        # set value to progress bar
        bar.setValue(40)
  
        # setting alignment to center
        bar.setAlignment(Qt.AlignCenter)
  
        # setting text visibility to false
        bar.setTextVisible(False)
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
