PyQt5 QCalendarWidget – 检查导航栏是否可见

在本文中，我们将了解如何检查 QCalendarWidget 的导航栏是否可见。导航栏是日历的顶部，用于更改下个月、上个月、月份选择、年份选择。默认情况下，导航栏是可见的，尽管我们可以随时使用 setNavigationBarVisible 方法将其隐藏，下面是 QCalendarWidget 导航栏的表示。

In order to do this we will use isNavigationBarVisible method with the QCalendarWidget object.
Syntax : calendar.isNavigationBarVisible()
Argument : It takes no argument
Return : It returns bool

编程需要懂一点英语

下面是实现

Python3

# 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 components
    def UiComponents(self):
 
        # creating a QCalendarWidget object
        calendar = QCalendarWidget(self)
 
        # setting geometry to the calendar
        calendar.setGeometry(10, 10, 400, 250)
 
        # hiding the navigation bar
        calendar.setNavigationBarVisible(False)
 
        # creating label
        label = QLabel(self)
 
        # setting geometry to the label
        label.setGeometry(100, 270, 250, 60)
 
        # making label multi line
        label.setWordWrap(True)
 
        # checking if the navigation bar is visible
        check = calendar.isNavigationBarVisible()
 
        # setting text to the label
        label.setText("Navigation Bar Visible : " + str(check))
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())

输出：
