PyQt5 QCalendarWidget – 获取鼠标跟踪属性

在本文中，我们将了解如何将鼠标跟踪属性添加到 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。我们可以借助setMouseTracking方法设置鼠标跟踪属性。

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

Syntax : calendar.hasMouseTracking()

Argument : It takes no argument

Return : It return bool

编程需要懂一点英语

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)
  
        # creating label to show the properties
        self.label = QLabel(self)
  
        # setting geometry to the label
        self.label.setGeometry(100, 280, 250, 60)
  
        # making label multi line
        self.label.setWordWrap(True)
  
        # getting mouse tracking
        value = self.calendar.hasMouseTracking()
  
        # setting text to the label
        self.label.setText("Mouse Tracking ? : " + str(value))
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出：
