PyQt5 QCalendarWidget – 设置鼠标跟踪属性

在本文中，我们将看到如何将鼠标跟踪属性设置为 QCalendarWidget。如果禁用鼠标跟踪（默认设置），则只有在移动鼠标时至少按下一个鼠标按钮时，日历才会接收鼠标移动事件。如果启用了鼠标跟踪，即使没有按下任何按钮，日历也会收到鼠标移动事件。

In order to do this we will use setMouseTracking method with the QCalendarWidget object.
Syntax : calendar.setMouseTracking(True)
Argument : It takes bool as argument
Return : 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, 650, 400)
 
        # calling method
        self.UiComponents()
 
        # showing all the widgets
        self.show()
 
    # method for components
    def UiComponents(self):
 
        # creating a QCalendarWidget object
        self.calendar = QCalendarWidget(self)
 
        # setting geometry to the calendar
        self.calendar.setGeometry(50, 10, 400, 250)
 
        # setting cursor
        self.calendar.setCursor(Qt.PointingHandCursor)
 
        # enabling mouse tracking
        self.calendar.setMouseTracking(True)
 
         
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())

输出 ：
