PyQt5 QDateEdit – 使其只读
在本文中,我们将了解如何将日期编辑设为只读。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。
为了做到这一点,我们使用带有setReadOnly
对象的 setReadOnly 方法
Syntax : date.setReadOnly(True)
Argument : It takes bool as argument
Return : It returns 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
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)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
