PyQt5 QCalendarWidget – 检查导航条是否可见
在这篇文章中,我们将看到我们如何检查QCalendarWidget的导航栏是否可见。导航栏是日历的顶部部分,用来改变下个月、上个月、月份选择、年份选择。默认情况下,导航条是可见的,尽管我们可以在任何时候借助setNavigationBarVisible方法来隐藏它,下面是QCalendarWidget的导航条的表示。
为了做到这一点,我们将使用QCalendarWidget对象的isNavigationBarVisible方法。
语法: calendar.isNavigationBarVisible()
参数: 它不需要参数
返回: 它返回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 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。
