PyQt5 QCalendarWidget – 将坐标系映射到全局

在本文中，我们将了解如何将坐标系从 QCalendarWidget 映射到全局。为此，我们使用mapToGlobal方法，它将小部件坐标位置转换为全局屏幕坐标。例如， mapToGlobal(QPoint(0, 0)) 将给出日历左上角像素的全局坐标。

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

Syntax : calendar.mapToGlobal(point)

Argument : It takes QPoint object as argument

Return : It return QPoint object

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
  
# 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 global
        value = self.calendar.mapToGlobal(QPoint(50, 10))
  
        # setting text to the label
        self.label.setText("Mapped Point from calendar to global : " + 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：
