PyQt5 QCalendarWidget – 检查是否有水平标题

在这篇文章中，我们将看到我们如何检查QCalendarWidget是否有水平头。水平头是QCalendarWidget中显示日子名称的地方，默认显示日子的缩写，例如星期一显示为Mon，下面是水平头的表现。

水平头可以通过覆盖QCalendarWidget的结构或者将头的格式值设置为0来移除，因此为了检查是否有头，我们必须得到头的值并与0值进行比较以知道是否有头。

下面是实现的过程

# 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。
