PyQt5 QCalendarWidget – 使其成为活动窗口

在本文中，我们将了解如何使 QCalendarWidget 成为活动窗口。活动窗口是具有键盘输入焦点的可见顶级窗口。使其成为活动窗口会将包含此日历的顶级小部件设置为活动窗口。

注意：窗口必须可见，否则 activateWindow() 无效。

In order to do this we will use activateWindow method with the QCalendarWidget object.

Syntax : calendar.activateWindow()

Argument : It takes no argument

Action Performed : It return None

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
        calender = QCalendarWidget(self)
  
        # setting geometry to the calendar
        calender.setGeometry(10, 10, 400, 250)
  
        # setting name
        calender.setAccessibleName("Geek Calendar")
  
        # making it an active window
        calender.activateWindow()
          
  
         
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
