PyQt5 QCalendarWidget – 设置掩码

在本文中，我们将看到如何将掩码设置为 QCalendarWidget。遮罩基本上是用来隐藏日历的，在遮罩的帮助下，用户将无法看到整个日历，虽然日历仍然存在，但上面会有遮罩。

它仅导致位图具有相应 1 位的日历像素可见。如果该区域包括日历矩形之外的像素，则该区域中的窗口系统控件可能可见也可能不可见，具体取决于平台。

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

Syntax : calendar.setMask(region)

Argument : It takes QRegion object or QBitMap object as argument

Return : It return None

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)
  
  
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 geometry to the calendar
        self.calendar.setGeometry(20, 20, 300, 240)
  
        # QRect object
        rect = QRect(10, 10, 200, 100)
  
        # creating a QRegion
        region = QRegion(rect)
  
        # setting mask to the calendar
        self.calendar.setMask(region)
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出：
