PyQt5 QDateEdit – 获取只读属性

在本文中,我们将看到如何获得日期编辑的只读属性。默认情况下,当我们创建日期编辑时,它是可编辑的,尽管我们可以将其设为只读。在只读模式下,用户仍然可以将文本复制到剪贴板,或者拖放文本但不能编辑。为了使日期编辑只读,我们使用setReadOnly方法。

为了做到这一点,我们使用带有 QDateEdit 对象的isReadOnly方法

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
  
  
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 QDateEdit widget
        date = QDateEdit(self)
  
        # setting geometry of the date edit
        date.setGeometry(100, 100, 200, 40)
  
        # alignment
        a_flag = Qt.AlignCenter
  
        # setting alignment of date
        date.setAlignment(a_flag)
  
        # making date edit read only
        date.setReadOnly(True)
  
  
        # creating a label
        label = QLabel("GeeksforGeeks", self)
  
        # setting geometry
        label.setGeometry(100, 150, 250, 60)
  
        # making label multiline
        label.setWordWrap(True)
  
        # getting read-only property
        value = date.isReadOnly()
  
  
        # setting text to the label
        label.setText("Read Only ? " + 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 :
