PyQt5 QCalendarWidget – 设置移动事件

在本文中，我们将了解如何实现 QCalendarWidget 的移动事件。此事件处理程序可以在子类中重新实现，以接收在事件参数中传递的日历移动事件。当日历收到这个事件时，它已经在新的位置。

下面是日历类的代码

# QCalendarWidget Class
class Calendar(QCalendarWidget):

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

    # override the move event
    def moveEvent(self, event):
        print("Calendar Moved")

Implementation steps:
1. Create a Calendar class that inherits the QCalendarWidget
2. Inside the Calendar class override the moveEvent and inside the event print the text
3. Create a main window class
4. Create a Calendar object inside the main window
5. Set various properties to the calendar

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)
        self.setMouseTracking(True)
  
    # override the move event
    def moveEvent(self, event):
        print("Calendar Moved")
  
  
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(300, 240)
  
        # move the calendar
        self.calendar.move(10, 10)
  
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：

Calendar Move
