PyQt5 QCalendarWidget - 检查是否有水平标题

在本文中，我们将了解如何检查 QCalendarWidget 是否具有水平标题。水平标题是 QCalendarWidget 中默认显示日期名称的地方，短形式的日期显示例如星期一显示为星期一，下面是水平标题表示。

可以使用覆盖 QCalendarWidget 的结构或通过将标题格式值设置为 0 来删除水平，因此为了检查是否有标题，我们必须获取标题的值并与 0 值进行比较才能知道是否有标题。

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)
 
        # removing horizontal header
        calendar.setHorizontalHeaderFormat(0)
 
        # creating a label
        label = QLabel(self)
 
        # setting geometry to the label
        label.setGeometry(100, 280, 250, 60)
 
        # making label multi line
        label.setWordWrap(True)
 
        # getting the horizontal header value
        value = calender.horizontalHeaderFormat()
 
        # text
        text = "There exist horizontal head"
 
        # comparing value with 0
        if value == 0:
            text = "There is no horizontal head"
 
        # setting text to the label
        label.setText(text)
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())

输出 ：
