Python PyQt5 – 隐藏进度条？

在本文中，我们将了解如何在 PyQt5 应用程序中隐藏进度条。我们可以通过两种方式隐藏进度——

1. 使用hide方法。
2. 将进度条的可见性状态设置为 False。

方法#1：

借助hide方法，我们可以隐藏进度条。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(200, 100, 200, 30)
  
        # setting the value
        bar.setValue(100)
        bar.setFormat("Welcome geeks to geeks portal")
  
        # setting alignment to center
        bar.setAlignment(Qt.AlignCenter)
  
        # hiding the progress bar
        bar.hide()
  
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
方法#2：

借助SetVisible方法，我们可以隐藏进度条。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(200, 100, 200, 30)
  
        # setting the value
        bar.setValue(100)
        bar.setFormat("Welcome geeks to geeks portal")
  
        # setting alignment to center
        bar.setAlignment(Qt.AlignCenter)
  
        # setting visibility status to False
        bar.setVisible(False)
  
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
