PyQt5 QCalendarWidget 为月份菜单设置边框

在这篇文章中，我们将看到如何为QCalendarWidget的月份菜单设置边框。月份菜单是日历的QMenu对象的子对象，当用户按下月份名称时，它就会出现，这样用户就可以选择月份，给QCalendarWidget设置边框不像给其他小部件设置边框，日历是小部件，它有很多子部件，即组件，我们也可以给独立组件设置边框。下面是在月份菜单上设置边框的日历看起来是怎样的

为了做到这一点，我们将使用QCalendarWidget对象的setStyleSheet方法，下面是样式表的代码

QCalendarWidget QMenu
{
border : 4px solid green;
}

以下是实现的过程

# importing libraries
from PyQt5.QtWidgets import * 
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import * 
from PyQt5.QtCore import * 
import sys

# QCalendarWidget Class
class Calendar(QCalendarWidget):

    # constructor
    def __init__(self, parent = None):
        super(Calendar, self).__init__(parent)



class Window(QMainWindow):

    def __init__(self):
        super().__init__()

        # setting title
        self.setWindowTitle("Python ")

        # setting geometry
        self.setGeometry(100, 100, 500, 400)

        # calling method
        self.UiComponents()

        # showing all the widgets
        self.show()


    # method for components
    def UiComponents(self):

        # creating a QCalendarWidget object
        # as Calendar class inherits QCalendarWidget
        self.calendar = Calendar(self)

        # setting cursor
        self.calendar.setCursor(Qt.PointingHandCursor)

        # setting size of the calendar
        self.calendar.resize(350, 240)

        # move the calendar
        self.calendar.move(10, 10)

        # setting stylesheet
        # adding border to the QMenu
        self.calendar.setStyleSheet("QCalendarWidget QMenu"
                                    "{"
                                    "border : 4px solid green;"
                                    "}")


# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())

输出：
