PyQt5 QSpinBox – 使用 isHidden 检查它是否隐藏

在本文中，我们将了解如何借助isHidden方法检查旋转框是否隐藏。我们可以使用hide方法或setHidden方法隐藏旋转框。默认情况下，旋转框是可见的。

为此，我们使用isHidden方法。

Syntax : classs_object.spin_box.isHidden()

Argument : It takes no argument

Return : It returns bool

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 spin box
        self.spin = QSpinBox(self)
  
        # setting geometry to spin box
        self.spin.setGeometry(100, 100, 250, 40)
  
        # setting prefix to spin
        self.spin.setPrefix("Prefix ")
  
        # setting suffix to spin
        self.spin.setSuffix(" Suffix")
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# checking if the spin box was hidden
check = window.spin.isHidden()
  
# printing the status
print(check)
  
# start the app
sys.exit(App.exec())

输出 ：

False
