PyQt5 QCalendarWidget - 将坐标系映射到父级

在本文中,我们将看到如何将坐标系从 QCalendarWidget 映射到父级。为了做到这一点,我们使用 mapToParent 方法,它将小部件坐标位置转换为父小部件中的坐标。

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
 
# QCalendarWidget Class
class Calendar(QCalendarWidget):
 
    # constructor
    def __init__(self, parent = None):
        super(Calendar, self).__init__(parent)
 
 
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
        # as Calendar class inherits QCalendarWidget
        self.calendar = Calendar(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)
 
        # mapping from calendar co-ordinate system to parent
        value = self.calendar.mapToParent(QPoint(50, 10))
 
        # setting text to the label
        self.label.setText("Mapped Point from calendar to parent : " + 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 :
