PyQt5 – 进度条的 isTextVisible() 方法

当我们创建进度条时，默认情况下百分比是可见的。虽然我们可以使用setTextVisible方法来改变文本的可见性状态。 isTextVisible方法用于检查进度条中的文本可见性状态。

Syntax : bar.isTextVisible()

Argument : It takes no argument.

Return : It return bool, True if text is visible and False if text is 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)
  
        # getting the visibility status
        visible = bar.isTextVisible()
  
        # creating label to print visibility status
        label = QLabel("Text visibility status = " + str(visible), self)
  
        # adjusting the size of label
        label.adjustSize()
  
        # moving the label
        label.move(160, 200)
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
