PyQt5 QCalendarWidget - 为导航栏设置边框

在本文中，我们将了解如何为 QCalendarWidget 的导航栏设置背景颜色。在日历导航栏是顶部的栏，由一些按钮组成，为 QCalendarWidget 设置背景与为其他小部件设置背景颜色不同，日历是具有许多子组件的小部件，我们也可以将边框设置为独立组件。下面是带有背景颜色的导航栏的外观

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

QCalendarWidget QWidget#qt_calendar_navigationbar
{
background-color : lightgreen;
}

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
  
# 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 background color to the calendar's navigation bar
        # adding another background color when mouse hover over it
        self.calendar.setStyleSheet("QCalendarWidget  QWidget# qt_calendar_navigationbar"
                                    "{"
                                    "background-color : lightgreen;"
                                    "}"
                                    "QCalendarWidget  QWidget# qt_calendar_navigationbar::hover"
                                    "{"
                                    "background-color : cyan;"
                                    "}")
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
