PyQt5 QCalendarWidget – 抓取矩形

在本文中，我们将了解如何从 QCalendarWidget 中获取矩形。抓取矩形意味着将日历呈现为受给定矩形限制的像素图。如果日历有任何子元素，那么它们也会被绘制在适当的位置。

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

Syntax : calendar.grab(rectangle)

Argument : It takes QRect object as argument

Return : It return QPixmap object

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)
  
        # 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)
  
        # rectangle
        rec = QRect(50, 10, 100, 100)
  
        # grab
        value = self.calendar.grab(rec)
  
        # setting text to the label
        self.label.setText("Pixmap : " + 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：
